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.

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.
