The Paraguayan President who Brought his Country to Military Catastrophe – Part 4: How the War Ended

Francisco Solano Lopez was president of Paraguay from 1862 to 1870. He led the country during one of the most devastating defeats in all history – the War of the Triple Alliance. Here, Erick Redington concludes this fascinating series by looking at how a Brazilian leader managed to take Humaita and the capital, Asuncion – and how Marshall Lopez continued to resist even after these captures.

The 1868 Battle of Avay.

Marshal Lopez knew about all the changes in the Allied high command. He was kept informed through an intelligence network of spies and sympathizers. The changes could only have been encouraging. With Mitre gone, and Argentina facing internal dissention and rebellion, their contribution to the war would be diminished at worst, and eliminated at best. Flores' term ending, and then assassination, meant that Uruguay would have another round of internal problems, which could only work to the Marshal's favor. Then the elephant in the room, Brazil. The new commander was probably just some other decadent Brazilian noble with a fancy title, but no match for the Marshal's military genius. 

There were reasons for the Marshal to be confident. Sure his armies were ill equipped, ill fed, and his country was significantly outweighed. But these facts had been true from the start. Yet, despite all this, he had survived. Paraguay had survived. The strategy of making the Allies pay for every step, letting the terrain and disease take their tolls, seemed to be working. The Allies were barely into Paraguay. Tens of thousands had been killed or invalided out. The Argentines and Uruguayans were seemingly withdrawing from the war. There had been no uprising against his rule. The nascent Paraguayan Legion, full of his opponents, was stymied. For the Marshal, all that seemed necessary was just a little more exertion, if the Paraguayan people could give just a little more, then a peace he could live with could finally be achieved.

For Lopez, the seeming successes (or non-failure depending on your perspective) were further convincing him of his own correctness, and the baseness of his opponents. He had done this himself. The American minister to Paraguay once wrote that the Marshal had many flatterers, but no advisors. The Marshal had stymied the Allies, and this led to a further inflated ego. Other issues began to rear their heads. Lopez did not share in the privations of his soldiers. He was a known gourmand, and would eat enormous amounts of food, even specialty cakes that would have been unthinkable for anyone not in the Marshal's immediate family. Worse, Lopez would drink large amounts of alcohol. Prior to modern sanitary methods, drinking alcohol did not carry the risks of disease, such as dysentery, that drinking unclean water did. However, Lopez's consumption of alcohol grew over the years of the war, and when he drank too much, he was known to lash out at those around him angrily. These scenes of anger would not bode well for the future.

When the Marquis de Caxias took command, he trained, organized and equipped his forces. As a veteran of every war of the Empire, he knew the importance of morale and logistics, and was determined to avoid the mistakes of his predecessors. Whereas the Marshal had assumed that Caxias was going to be another dull Brazilian nobleman, it was Caxias who would rebuild the Brazilian forces, and use the newfound unity of command to wield the Allied army and navy as one instrument for the destruction of Marshal Lopez.

Humaitá Falls      

By July 1867, Caxias was ready to move the Allied Army. President Mitre had made some rumblings about wanting to return to the army to reassume command, and Caxias had to move fast to maintain his operational control. The goal was Humaitá. The Marshal had used the months of inactivity to strengthen the Gibraltar of South America. One element that the Marshal had not counted on was the advancements in naval technology of the previous decade. When Humaitá was originally built by Carlos Antonio Lopez, naval vessels were still primarily made of wood, and steam propulsion was new. The bend in the river would slow ships and the guns of the fort would bring their destruction. With ironclad warships becoming more common, even in South America, the position Humaitá was in was not as impregnable as it had been.   

Utilizing terrain and slowing down the Allies, the Marshal wanted to make his enemies bleed for every foot of Paraguayan ground they stepped on. Caxias was willing to accept casualties in order to encircle the Paraguayan fortress. Being outnumbered almost 2-1, however, limited the Marshal's options and he could not afford a pitched battle. For the Marquis, a pitched battle was what he wanted. He was simply unable to achieve it at this stage. Lopez knew his numbers were low, and he had limited prospects of getting more men. Pre-teen boys and old men were being conscripted into the Paraguayan army. These young men would prove some of the Marshal's most devoted followers. The use of child soldiers would be one of the biggest stains on the Marshal's record and is one of the greatest controversies of the war. For the Paraguayans, they felt they had no alternative. According to the Marshal's propaganda, the Allies were going to partition the country and the Brazilians were going to enslave them. These were motivations to get families to freely give up their children for service. And besides, these children would be under the command of the brilliant Marshal Lopez, who would ensure their safety.

The Marquis would order a wide flanking maneuver to surround the fortress, then when close positions were attained, begin land and naval bombardments. If the Paraguayans would not evacuate, Humaitá would be besieged and the Paraguayan army trapped inside, hopefully with the Marshal as well. Mostly, this is what happened. However, due to the terrain, it was impossible to completely surround Humaitá as closely as the Marquis would have liked. Despite this the Allied army was able to take up positions facing Humaitá, and the siege was on. The defense of this place had been built up in the minds of both sides that immediate evacuation by the Marshal was impossible. For both sides, it was the focus of the war. As long as it held out, there was still hope for the Paraguayans. If it fell, the Allies hoped they would have an open road to Asunción.  

As has been seen, Marshal Lopez was not one to sit and wait for anything to happen to him. He would make attacks during the siege, and at times put the Allies back on their heels. Active defense seemed to be the tactic Marshal Lopez excelled at. But his army was also starving. A larger proportion of his solders everyday was made up of children and old men. Weapons were outdated. Ammunition and powder were short. It was amazing the Paraguayans held on as long as they did. But the Marshal could feel the squeeze he was being put under. Slowly, steadily, month after month, the Allies strangled the Paraguayans. The Brazilians showed early in the siege that their ironclads were able to run the guns of the fortress and make it up river, virtually defeating the purpose of the fortress at that location. With the fleet now able to go upriver and shell Paraguayan positions, Humaitá slowly became untenable. Small-scale counter attacks would not be enough. The Allies inexorably closed in. But no matter how many counter attacks, ambushes, and disruptions to the Allied supply line the Marshal made, he could not shake the grip that Caxias had on Humaitá. It became a matter of time. 

Marshal Lopez was not a man to sacrifice himself in the last ditch defense of the fortress. Nor would he allow himself to be captured by his enemies while there were still Paraguayan soldiers left to carry on. Leaving a small force to man the fort and maintain a semblance of their presence, the Marshal ordered his troops to retreat further north. The Marquis was prepared to assault the fortress that for so long had frustrated Allied designs. When the Allies were prepared for the final assault, negotiations began for surrender. Over 1,200 Paraguayan troops surrendered. These men were starving and sick. Their commander, Colonel Martinez, was so starved, by one report his skin had begun to turn yellow. Despite this, surrender by the Paraguayans up until this moment had been unthinkable. To the Allies, the Paraguayans were unthinking automatons in the service of a brutal dictator. Seeing the walking corpses come out of the fort that day reinforced their belief.

Things Fall Apart

For the Marshal, surrender had been unthinkable. He had only left orders for the evacuation of the sick and wounded, not understanding this meant the whole garrison. Although he had held out for longer than anyone had the right to expect, with the fortress gone, he now began to worry about the safety of his capital. Retreat north was a necessity. The Marquis, however, was not willing to rest on his laurels and savor the triumph. Further naval probes were ordered. The advance would continue.

Before confronting his enemies in front of him, Lopez confronted his perceived enemies behind him. This would be the start of one of the greatest black marks against the Marshal’s character. Paraguay was an authoritarian state, and the Marshal was used to instant obedience. It seems that when his orders had been disobeyed and Humaitá surrendered, Lopez began to delude himself with the idea that there was a massive conspiracy against him personally. Massive numbers of arrests were made. Everyone from foreign travelers to government officials were arrested and subject to extreme forms of torture to extract confessions. Priests were used as informants and the confessional was no longer sacred. Families would inform on each other. Even the Marshal’s family was not immune. His brother would be arrested, and his mother would be tortured for the sin of telling him that he was born out of wedlock. Plots to overthrow the Marshal or to surrender to the Allies were allegedly everywhere. Historians have debated whether any of this conspiracy mongering was based in fact, but there is very little evidence. One result did come about. If no one was willing to challenge the Marshal before, now there was no one left in government or the inner circle who would even think of telling the Marshal the truth about the situation again.

Lopez looked for a defensible position from which to stymie the Allied advance. He settled on the banks of the Piquissiri River south of Asunción. It was here the Marquis would show himself a superior general to the Marshal. Caxias would cross the river, enter the terrible terrain of the Gran Chaco and flank the Paraguayan army. Then he could take the Marshal from behind and destroy him before he could retreat further north. This is exactly what happened. At the Battle of Avay, much of the remaining Paraguayan army was destroyed. With this, there was nothing stopping the Marquis from taking the Paraguayan capital, which was done on New Year’s Day 1869.

The Fall                   

Although the Allies hoped that taking the Paraguayan capital would end the war, that would not be signaled until the Marshal was removed from the board. Ever the survivor, Lopez fled north into the wilderness and the mountains. He would take whatever boys and old men were left, form a new army, and fight a guerilla war against the Allies and their newest ally, the Paraguayan Provisional government. This group was set up by the Allies to govern the country. For Lopez, this group of men was even worse than Brazilians, they were traitors. Many Paraguayans would see them the same way. The war would continue.

For over a year, the Marshal would fight his guerilla war. The Marquis de Caxias would leave the war zone, to be replaced by the Emperor’s son-in-law, the Comte d’Eu. There were more battles, but the primary result was more needless suffering by the Paraguayan people. The battles of the last year of the war would see whole villages burned to the ground and brutal reprisals and counter reprisals by both sides. D’Eu was determined to destroy the support system that sustained the Marshal’s armies and would brutally punish any area that gave the Marshal support. The Marshal would launch deadly attacks on anyone who aided the Allies or would not actively support him. Unlike many dictators who can allow passive acceptance, the Marshal required active participation in his activities by his people. The Marshal had no hope of victory, yet he would order the instant death of Paraguayans who even spoke of surrender. The Paraguayan people probably knew they were doomed, but what else could they do? The habituation of obedience had been with them since the days of Dr. Francia. There was nothing left for the Paraguayan people to do but to fight and die. 

The Comte d’Eu would order continuous campaigns to root out the Marshal. Finally, after all these years of war, Marshal Lopez was cornered. The Allies launched an attack on his camp and cut down his aides and camp followers. The Marshal, believing in his own importance to his cause, jumped on his horse and attempted to ride away. Due to the muck, getting away was not possible. Through the entire war, the Marshal had pointedly not exposed himself to danger. His supporters would say that due to his role as commander in chief and president, it would be irresponsible to expose himself. His detractors would call him a coward. At this moment, when all was lost, and escape was impossible, the Marshal found the courage to face his enemies. He was called upon to surrender by the Brazilians. He not only refused but insulted and swore at his attackers. He would curse and damn them for what they had done to Paraguay. The Brazilian commander, General Câmara, would order his men to capture the Marshal alive. No order could save the Marshal. Not only did the Brazilian troops have their blood up and adrenaline pumping, but the Emperor had offered a reward of £110 sterling for the man who would take the Marshal down. The Marshal, covered in wounds was shot in the chest and fell in the swamps of Northern Paraguay on March 1, 1870. His last words, spat with his last breath, were “I die with my country.”

Legacy

The memory of Marshal Francisco Solano Lopez Carrillo is complicated. To the Paraguayan people who he ruled over with an iron fist for most of a decade, he is a hero, a symbol of national resistance against overwhelming odds. He had defied the superpowers of South America, and though he lost, it was through his sacrifice that Paraguay was able to survive the worst war the continent had ever seen. Supporters say that the fact that Paraguay earned the respect of its’ enemies through its heroism and were moved to allow the country to survive is a testament to the Marshal. To detractors, he was a brutal dictator who launched a war that no sane person could have imagined for one moment he had a chance to win. This view is reinforced by the casualty figures. Of a prewar population of approximately 525,000, over 300,000 died. It is estimated that 90% of men in Paraguay died. This casualty figure surpasses the most brutal of wars, even the Eastern Front of World War II. 

Insane brutal dictator, or enlightened leader who was suppressed by his neighbor. These two positions polarize historians to this day. One thing the Marshal achieved, which he would have enjoyed, was eternal fame. The fame of leading one of the most epic campaigns in military history, fighting against impossible odds, and enacting a true Götterdämmerung will make his name live forever.

The Paraguayan President who Brought his Country to Military Catastrophe – Part 3: Devastating Battles for Both Sides

Francisco Solano Lopez was president of Paraguay from 1862 to 1870. He led the country during one of the most devastating defeats in all history – the War of the Triple Alliance. Here, Erick Redington continues this fascinating series by looking at the events in the War of the Triple Alliance, including the Battle of Tuyutí and the Battle of Curupayty.

If you missed it you can read part 1 on the early life of Francisco Solano Lopez here and part 2 on the start of the War of the Triple Alliance here.

A depiction of the Battle of Curupayty.

With Marshal Lopez's advance into Corrientes stunted, he knew that pushing all the way to Uruguay was no longer possible. He had achieved much by aggressively invading the Allied Powers. Their armies had been thrown back on their heels, causing increased dissention between the Brazilians and Argentinians, Lopez's only real hope of victory. A wealth of materiel was captured by the Marshal's army aiding the war effort immensely. The small Paraguayan industrial base would have difficulty throughout the war supplying the army with the materiel it needed to fight. The small Paraguayan nation was proving itself to be very dangerous to its larger neighbors. To some, Lopez looked brilliant. To no one more so than the Marshal himself. 

The Allies knew they would have to control the rivers in order to maintain their supply chain. The first Allied target was Humaitá, called the "Gibraltar of South America." They knew that as long as the fortress held out, they would not be able to advance further into Paraguay and take the capital, Asuncion. The Marshal knew this as well. He was determined to use every effort to defend the fort. But he knew that Humaitá needed further reinforcing. Therefore, the best strategy would be to delay the Allies as long as possible in order to improve the fortifications. In the process, the Allies would further bleed, and potentially, greater dissention would grow between the Brazilians and Argentinians. 

The Marshal also knew that Argentina was fragile at this time. President Mitre had assumed office only a few years before, after yet another civil war. Lopez knew that there were many elements within Argentina who were very sympathetic to him and were perfectly happy to see Marshal Lopez create a strong Paraguay. To these Argentinians, Paraguay was the wrong enemy at the wrong time. The right enemy would always be Brazil. The war would be used throughout as a weapon to attack those in power in Argentina. President Mitre himself was tired of the condescension with which he was treated by the Brazilian officers. They saw him as just another caudillo in a long string of caudillos ruling Argentina. The Marshal hoped that if he could inflict a few further defeats on the Allies, one or both would be willing to come to the peace table and Lopez could get a peace he could live with, rather than the partition and exile that the Treaty of the Triple Alliance called for.

The Marshal Counters

The Brazilian naval commander, Baron Tamandaré would use his fleet to advance further up the river system to allow the Allies to invade Humaitá. When the Allies made a landing at the town of Riachuelo, Lopez sensed an opportunity. The Marshal was not a man to sit back and just take what was coming, so he ordered his fleet to attack the Brazilians. The Paraguayan navy was heavily outnumbered.  The Brazilians had better armored ships with more guns. None of this mattered. What mattered was élan. Lopez would fling his navy in a night attack against the Brazilian fleet and in one brilliant move end the threat of an Allied offensive by having his sailors board the Brazilian ships under the cover of darkness, capture them, and then sail the new prizes back up the river to reinforce the Paraguayan fleet.

Of course, this is not what happened. The ships arrived after sunrise. The Paraguayan commander ordered his ships to pass the Brazilian ships and fire on the ground troops. The Paraguayans would lose more ships and have to retreat upriver. It was a disaster for the Paraguayan navy. Marshal Lopez impetuously ordered his fleet to attack an enemy that heavily outnumbered him with a confusing and frankly ridiculous battle plan to not only defeat the Brazilians but also augment his own fleet. Why did he do this? As we have seen, it was in the nature of the man to take risks and wager everything on bold, Napoleonic, plans. As someone who believed he was a military genius, he believed his plans could work. As a brutal dictator in charge of a police state, no one was brave or foolhardy enough to tell him otherwise. Due to this, a sizable part of the Paraguayan fleet that could have been used in the defense of Humaitá was lost, and future defenses were weakened.

By 1866, the Allies were finally prepared to begin what they saw as the war-winning offensive. The Allies crossed the Paraná River and entered Paraguay. The Marshal was a believer in the offensive-defensive strategy. He did not make a general, theater-wide offensive, but he began launching localized counterattacks to make the Allies keep their guard up and slow their advance. This was in keeping with the Marshal's character, but it was also the sound military move. The Marshal knew this would be a war of attrition. He had to make the Allies bleed. He needed to cause further dissention. Passively waiting to be strangled would only lead to being strangled. He had to fight. 

The local counterattacks, while not leading to battlefield victories, worked their intended purpose. The Paraguayans were able to slow down the Allies, stopping their advance at Estero Bellaco for a time. The Marshal began to grow more confident. He had been mostly successful in his strategy so far. With his increasing confidence grew his willingness to gamble. He now began to envision knocking out the Allied army with one decisive blow. When the Allies began advancing again, Lopez decided to strike the blow. The bloodiest battle in the history of South America began, the Battle of Tuyutí.

Tuyutí

With the Brazilians on the left, the Uruguayans in the center and the Argentines on the right, the Allies were drawn up in a flat, swampy area. The Marshal decided to focus his attacks on the Brazilians and the Uruguayans. Lopez had a very low opinion of Brazilians, and the Uruguayans were the smallest contingent. Initially, the Paraguayans made gains, however the Brazilian artillery would seal the fate of the Paraguayan army, and the Allies came away with the victory. The importance of the victory was not that the Allies won the battle, but that it had been so deadly.

Statistics from the Paraguayan army at this time are problematic at best. Due to the dictatorial nature of the country, and the importance that Lopez placed on propaganda, reported casualty figures from the Paraguayans can be taken sometimes with a grain of salt. The best estimates for battlefield losses were 6,000 dead and 7,000 wounded out of an army of about 25,000 men. The Allies lost over 5,000 men out of about 35,000. For the Allies, the losses were terrible, though replaceable. For the Paraguayans, this was a national catastrophe. Based upon prewar population, the losses in this battle represented over 3% of the people in the entire country. These men represented the cream of the large pre-war army the Marshal had accumulated and led into Argentina and Brazil. His army would never recover. Never again would the Marshal order a mass attack on the Allies. 

With victory comes overconfidence. The Allies, having achieved a major victory now began to advance more rapidly against the Marshal. Where other men would draw back in the aftermath of such a catastrophic defeat, Lopez was as defiant as ever. The Paraguayan army would go on to defend itself well against Allied advances. However, at the Battle of Curuzu, the Paraguayans were defeated again and finally Marshal Lopez was growing concerned. He decided to try a different tack, one which he had not utilized so far: diplomacy.

The Marshal Tries Diplomacy     

With the Allies on the move, and getting closer to Humaitá, the Marshal hoped to capitalize on the war-weariness of his opponents. He unexpectedly invited the Allied leaders to a conference to try to end the war. The Brazilians wanted nothing to do with this conference and refused to negotiate with the Marshal. President Mitre, however, decided to meet his enemy. For Mitre, beset by political opposition at home, facing rebellion in outlying provinces, and weary over his own conduct of the campaign (he was supreme Allied army commander, after all), Mitre wanted to find a way to end the war. For Lopez, this represented a wonderful opportunity. Despite his reputation as an insane warmonger, it was said that in person the Marshal could be very charming and a great conversationalist. He was very well read and quick-minded. For Lopez, this was finally his chance to divide the Allies, get Argentina to leave the war, and then take on the enemy he hated, the Brazilians. And he failed miserably. 

Accounts of the meeting vary, with some saying that the conversation was amicable, and others saying the two men got into an argument. Either way the conference was a failure. President Mitre told President Lopez of his determination to abide by all clauses of the Treaty of the Triple Alliance. This included the article demanding the removal of the Marshal from power before any peace could be had. Lopez could have agreed and lived a comfortable life in exile in Europe or North America. Instead, he refused. He would fight on to the bitter end. And that is exactly what would happen. No peace, but war, war to the knife.

After the failure of the conference, Mitre decided to restart the offensive and attempt to deal the killer blow, reach Humaitá, and from there to Asunción. The invasion of Paraguay was on. The Allied army approached the Paraguayan army entrenched at Curupayty. The Paraguayans had used the truce to improve their fortifications and build further defenses. They had brought in artillery and reinforced the trenches. The Paraguayans only numbered about 5,000 men, a quarter of the advancing Allied force. In their confidence after Tuyutí, many in the Allied camp believed the Paraguayans were on their last legs and ready to fall apart. This overconfidence led to Mitre preparing a battle plan whereby the Brazilian navy would shell the Paraguayans from the river, and once softened up, the Allies would launch a grand assault to rout the enemy. Once the fleet had finished the bombardment, Mitre ordered the men in. 

The Battle of Curupayty can be likened to other thoughtless slaughters like Cold Harbor or the Somme. Allied troops went in and were massacred. The Paraguayans only lost about 50 men in the battle. The Allies, however, lost about 9,000, according to the best estimates. It was a shocking and devastating loss, but it could have been worse for the Allies. The commander of the Paraguayan army was not Marshal Lopez. He would never expose himself to battlefield danger. That was not his way. The field commander was General José Diaz, a good commander in his own right, but he operated within the Paraguayan system of nothing is done without the dictator's permission. Even considering the casualties, the Paraguayans were still outnumbered and outgunned, but they had morale on their side. If they had counterattacked and pursued the Allies, a decisive, perhaps war turning victory could have been achieved. Diaz was not stupid. He was not going to take the initiative and incur the wrath of the Marshal. The Allies were allowed to withdraw back to their entrenchments. Here the war would sit for longer than any of the participants had anticipated. For the Allies Humaitá would have to wait. Recovery from the embarrassment of Curupayty would take far longer than anyone expected. They had much bigger problems at hand.

On the Pale Horse

Part of the original defense plan of Marshal Lopez was utilizing the geography of Paraguay to slow the Allies. Much of the country is located in tropical, low-lying swamps. These swamps bred interminable swarms of mosquitos and other insects. The mosquito was, and still is, a primary vector to transport infectious disease from person to person. For the Paraguayan troops, malnourished and under equipped, disease was a fact of life. For the Marshal, there was no ability to import medical supplies. The traditional Paraguayan cure-all for everything was yerba mate, which was obviously ineffective against infectious disease. Every man lost to disease was a man out of the gun line for the Marshal. There was very little he could do to stop the epidemics though. 

With the defeat at Curupayty, the Allies needed to rest and regroup before another advance. Camp life at this time was dull and unsanitary. Given the geography of the area the Allies found themselves, and the filth of the camps, it is no surprise that epidemics began amongst the Allied troops. Dysentery, cholera, and yellow fever were some of the worst. The conditions in the camps, coupled with the terrible defeat the Allies had taken, would lead to much needed changes within the Allied army, but this was small comfort to those who had been stricken.

Out With the Old…

After Curupayty, the squabbling between the Brazilians and Argentinians only grew worse. The Allied field commander, President Mitre, was called a bungler for directing one of the most lopsided losses in modern military history. Mitre was not happy either. He was growing tired of field service. Rebellions were breaking out against his rule in the outer provinces of Argentina. Many within his own government wanted peace. He believed in the necessity of the war still, but he did not believe that he would be the man to lead it. In January 1868, Mitre would leave his army and return to Buenos Aires.

Also out at this time was the President of Uruguay, Venancio Flores. He was also worn down with campaigning and would leave the army. His term as president was ending anyway, and he was to turn over his powers to a new leader from his Colorado Party. He would be assassinated four days after leaving office. The crime was never solved. 

For Marshal Lopez, these changes symbolized a weakening of his enemies' resolve to make war on him. What he did not know was that with Argentina mostly out of the war, and Uruguay effectively out of the war, the Allies would finally have solved the one major disadvantage they suffered through compared to the Paraguayans: unity of command. And that unity would come in the form of Luís Alves de Lima e Silva, the Marquis de Caxias.

The Paraguayan President who Brought his Country to Military Catastrophe – Part 2: The Start of the War of the Triple Alliance

Francisco Solano Lopez was president of Paraguay from 1862 to 1870. He led the country during one of the most devastating defeats in all history – the War of the Triple Alliance. Here, Erick Redington continues this fascinating series by looking at the outbreak of the War of the Triple Alliance and how Paraguay ended up facing Brazil, Argentina, and Uruguay in the war.

If you missed it you can read part 1 on the early life of Francisco Solano Lopez here.

The 1865 Battle of Riachuelo during the war.

While the immediate casus belli was caused by the seizure of a Brazilian steamer, the real beginning of the war was the Paraguayan invasion of the Brazilian territory of Mato Grasso. While a Paraguayan offensive against Brazil might look insane by referencing a map, the true balance of forces held more than a cursory glance would tell.

When Brazil entered the Uruguayan War, the Marshal grew worried about the balance of power. He understood that in a conventional military sense, Brazil would heavily outweigh tiny Paraguay. Brazil had a significantly larger population, and a much larger navy. What Paraguay had was a people used to hardship and deprivation. The habituation of following orders came naturally to people who grew up in a police state. This discipline and iron will would be what allowed a small nation to take on almost all of its neighbors and fight a long war of attrition against all odds. 

To mitigate the significant Brazilian advantages in population, resources, and space Marshal Lopez introduced universal conscription. Paraguay had a prewar population of about 450,000 so every available man had to be called to service. Raising this force was easier than arming and equipping it. Although Marshal Lopez's father had attempted to modernize the economy, and had made some impressive strides, no industrial base existed to meet the immediate needs of the army, let alone expand it to levels never before seen in the country. Little prospect existed for importing arms as well. Brazil's large navy had no problem declaring a blockade of the La Plata and on all Paraguayan river traffic. Throughout the war, Paraguay would be short ammunition, uniforms, artillery, food, and other war material. These shortages would only grow worse as all available men in the country were absorbed into the army. Arms would be inadequate as well. As the world's armies were transitioning to breech loading rifles and artillery, the Paraguayans would have smoothbore muskets little changed from before the Napoleonic Wars (except the Marshal’s personal bodyguard, which was always armed with the latest breechloading rifles). Despite the lack of modern equipment and supplies, the Paraguayan soldiers would show themselves capable of superhuman efforts. 

A major issue facing the Paraguayan army was the officer corps. Marshal Lopez had been Minister of War since 1855 and had handpicked the officer corps. Although some officers were foreign specialists in artillery and engineering, the line officers had been chosen based upon personal loyalty to the Marshal. Many of these officers were barely literate and did not have the type of training in military affairs that he had received. Lack of training and incompetence would be exhibited throughout the war with poor logistics and tactical handling of the troops in battle. Bravery and obedience were the two primary weapons in the Paraguayan arsenal. 

The lack of arms led the Marshal to order as his first offensive action of the war to invade the Brazilian province of Mato Grosso. While there, the Paraguayans burned a few villages and planted the Republic’s flag on Imperial territory. More important was the large quantity of Brazilian arms captured. These supplies would help alleviate the Paraguayan shortages throughout the first year of the war. Although the Marshal's armies would very quickly return to their territory, the invasion would nevertheless be an embarrassment to the Brazilians while providing a morale boost to the Paraguayan forces. 

Creation of the Triple Alliance

In another opening move, Marshal Lopez wanted to send reinforcements to his Blanco allies in Uruguay. While this may have been sound strategy, it would be a costly mistake and show the Marshal's impetuousness. In looking at a map, it is easy to see that Paraguay does not border Uruguay, making it difficult to directly send men to the Blancos. Due to this fact, Marshal Lopez requested of the Argentinian government permission to cross their territory to reach Uruguay. The President of Argentina, Bartolome Mitre, was in no mood to accommodate Paraguay. In the recent civil war in Argentina, Paraguay had sent troops to support Blanco-aligned rebel groups. Mitre was suspicious of Paraguayan motives, and the Marshal's large army. With control of his own country uncertain Mitre knew his country could not afford to become a base for the Paraguayan army to operate against Brazil. When the request reached him to allow the Paraguayan army to cross Corrientes province, it was refused. Since the Paraguayans did not have control of the river, there was no other way to reach Uruguay, so the Marshal ordered his troops to enter Argentina anyway. Lopez, already at war with Brazil and Uruguay, then declared war on Argentina, occupied the city of Corrientes, and declared the annexation of several Argentinian provinces.

With the declaration of war against Argentina, Brazil, Uruguay, and Argentina would sign a formal alliance for the conduct of the war. This treaty covered many of the things a normal treaty would cover, but there were several important parts. First, the Allies agreed to fight the war until the Government of Paraguay was overthrown. This meant the removal of Marshal Lopez as President and the dismantling of his government was a definite war aim. It further stated that the Allies agreed to respect the territorial integrity and independence of Paraguay while also delineating the future boundaries of the nations after the war, dismembering Paraguay in the process. The treaty was supposed to be secret, but very quickly made its way to the British, who then published it to the world, eventually making its way to the Paraguayans. Of course, a treaty which promised his deposition would enrage Marshal Lopez, and only furthered his resolve to fight the Allies to the finish. The Allied plans to carve up the country would go on to be very helpful for the Marshal’s propagandists to rally support for the war.

What was he thinking?

What could have led to such rashness? In the Marshal's mind, he had a window of opportunity to strike at the Brazilians occupying Uruguay before they had the chance to completely destroy the Blancos. Also, Paraguay had mobilized a large army. If it could use that army to strike the Argentinians first and knock them out of the war with one bold strike, his position would be significantly strengthened. Argentina had been weakened from near constant internecine strife and was not as strong as it first appeared. President Mitre was a successful general but knew his country's weaknesses, especially how divided it was. While many historians have viewed the Marshal's decision to take on the two biggest powers in the region as borderline insane, it was not quite as reckless as it appears with hindsight. 

But it was still reckless. This goes to another of the Marshal's character traits. He believed himself to be a brilliant military commander. He had studied the military all his life, after all. He had observed the Crimean War firsthand. He did believe in his own brilliance, and expected others to believe it as well. Raised on tales of great Napoleonic battles such as Austerlitz and Marengo, the Marshal's lesson from his historical studies was that fortune favored the bold, decisive stroke. So, he struck, and furthered the odds against himself long-term.

Marshal Lopez had a view of the Allies facing him that did not necessarily match reality and contributed to his overconfidence. For many years, Paraguayan propaganda had portrayed a very racist view of Brazilians to demonize them. Brazil was one of the last slave societies in the western hemisphere. Many of Brazil's wealthiest elites owned slaves. Although the Emperor was personally against slavery, he had found himself unable to abolish the institution. Due to the large numbers of Brazilians of African or mixed African decent, many Paraguayans held racist beliefs and stereotypes of Brazilian soldiers. Marshal Lopez would call Brazilians "monkeys" throughout the war.

His view of the Argentinians and Uruguayans was more charitable. He believed, and made many public statements, that Argentinians and Uruguayans were being used as "tools of the Empire" and, if they could only see the light, their opposition to him and his policy of the balance of power would disappear. Marshal Lopez seemed to genuinely believe in his own purity of motives for this war. Of course, any dissent from anyone under his power would be punished severely and no opposing views to this belief were heard in the Paraguayan capitol. 

This is one of the great downfalls of all-powerful dictators. They are caught in a self-confirmation bubble from which no unpleasant or dissenting information can reach. When he believed that the Argentinian and Uruguayan people would support him, no one was there to warn him of the insanity of that belief. Marshal Lopez, convinced of his own righteousness and brilliance, had no way of gaining an accurate picture of the situation his country was facing early in the war. 

Allied Squabbling

While the early attacks prevented the Allies from fully coordinating their war effort, the Paraguayans did not have the reserves of manpower and resources to sustain a war winning offensive. The Paraguayans could not even reach Uruguay. There was very little chance they could reach Buenos Aires. They had as much chance of capturing Rio de Janeiro as they did Paris or London. Once the Allies were able to coordinate themselves, the Paraguayans would have to stop the attacks and husband their strength. 

The Allies did begin to bicker amongst themselves. The Allied land commanders were counting on the Brazilian naval commander, the Baron of Tamandaré to clear the riverbanks for an advance against the Paraguayans. The humiliation of the successful raids by the Paraguayans led to Allied commanders on land to blame Tamandaré for their failure to advance. Alliance land forces were to be under the overall command of President Mitre, himself a general. As the initial encounters were under the command of Argentinian and Uruguayan generals, this scapegoating of the Brazilian admiral who commanded the naval forces created further strains in the Alliance. Unity of command would be one major advantage the Marshal would have over his opponents throughout the war. The allies were unsure of each other, jealous and unsparing of criticism. Marshal Lopez had total control of the troops under his command, while loyalty and fear inspired unquestioning obedience to his orders. 

Preparations for Defense

During the time Paraguayan forces were on Allied territory, the Marshal would take the opportunity to fortify the homeland in preparation for Allied invasion. After all, he had studied artillery and engineering since his teenage years and had observed early trench warfare on the Crimea. Terrain was the vital factor in the defense of Paraguay. Swampy and crisscrossed by multiple unfordable rivers, there were few natural avenues of invasion. The road network, despite the modernization efforts of President Carlos Lopez, was poor and no roads were all weather. The climate was tropical which led to infestations of insects, especially mosquitos. Where there are mosquitos, there are camp diseases such as malaria and yellow fever. The longer an army sits in one place the more unsanitary the area becomes, leading to more mosquitos and more disease including that great killer of 19th century armies, dysentery, which comes from polluted water. All these factors went into the building of one of the most formidable fortresses in the Western Hemisphere, Humaitá. 

To maintain their supply and have secure communications, the Allied armies would have to advance up the river system to invade Paraguay. The Marshal would turn all his talents to defending a bend in the Paraguay River at Humaitá. A fortified post had existed here since independence, but large-scale fortification had started under the elder Lopez stemming from fears of Argentinian invasion. By creating a large fort capable of heavy artillery emplacement and a strong garrison, the Allies would be unable to pass farther up the Paraguay River, and any ship attempting to run past the guns of the fort would have to slow down at the river bend and be blown to pieces. The landward side was covered by swamps and the approach was difficult. The defense of this fortress, and the Allied frustrations in attempting to take it, would define the next stage of the war.

For the Marshal and the Paraguayan people, the defense of Humaitá and what would follow would become the national epoch, a symbol of the national will and the determination of the Paraguayan people to defend their independence. This fortress would be the primary reason for the war lasting as long as it did. For Marshal Lopez, it would be the one thing that kept the Allies from defeating him and overthrowing his government. The survival of the army and the defenses of the Republic would determine if Paraguay itself survived. Everything would come down to Humaitá.
