World War II’s 1944 Battle of Anzio took place from January to June in Italy. It started following an Allied decision to attack this central part of Italy. William Floyd Jr. explains the background to battle and how it evolved over the first half of 1944.

In early November 1943, Adolf Hitler would sign a formal order stating there would be an “end of withdrawals.” In Italy, this would condemn a million German soldiers to the brutal combat that would soon follow. German Field Marshal Erwin Rommel, Hitler’s favorite general at the time, would leave the Mediterranean Theatre to over see the Atlantic Wall defenses in France for the expected Allied invasion.
Rommel, at the time, would state to a comrade that, “the war is as good as lost and hard times lay ahead.”
The Battle of Anzio was incredibly brutal and would cost thousands of Allied and German lives as well as the lives of Italian civilians. Anzio is a small town on the west coast of Italy on the Tyrrhenian Sea about thirty miles south of Rome. In the early morning hours of January 22, 1944, Allied troops of Fifth Army came ashore along a fifteen-mile stretch of Italian beach near the prewar resort towns of Anzio and Nettuno. The Allied landings could not have been carried out any better. German resistance was so light that British and American forces gained their first day’s objectives by noon, moving three to four miles inland by dark.
The local German commanders were surprised by the landings. They had been assured by their superiors that an amphibious assault would not take place during January or February. Within a week, the Allies would consolidate their positions and achieve a minor breakout from the beachhead. The Germans began to gather troops to eliminate what Hitler would call the “Anzio abscess.” The fighting over the next four months, on the Italian peninsula, would be some of the most savage of the war.
Agreeing the operation
The Anzio operation had been shelved on December 18, 1943, due to the fact that Anzio was too far ahead of the front to guarantee a swift overland hookup with the isolated vulnerable beachhead. However, changes of the command structure in the Mediterranean theatre would soon lead to the operation being revived. General Dwight Eisenhower would relinquish command of Allied forces in the Mediterranean to British General Sir Henry M. Wilson in January 1944. Eisenhower would become Supreme Allied Commander for Operation Overlord, the cross-channel invasion of France. Under Wilson the Anzio plan would be resurrected with the influence of British Prime Minister Winston Churchill playing a large roll. Despite their differences on certain aspects of strategy, both the Americans and the British were united in the hope that Italy, the weaker of the Axis partners, could be forced out of the war.
Anzio was not only within striking distance of Rome, the ultimate prize, but was also within range of Allied aircraft operating out of Naples. One week before the landings at Anzio, the Allied Fifth Army made up of U.S., British, and French units would mount an offensive on the German Gustav defensive position in the area of Cassino and plan to link up with the forces at Anzio for the drive on Rome. In the meantime, Allied forces of the Eighth Army were to break through on the Adriatic front or at least tie down German forces to prevent them from being sent to Anzio.
General Mark Clark had chosen Major General John P. Lucas, U.S. Army Commander of Fifth Army’s VI Corps to lead the Anzio invasion. Lucas’s orders were to divert enemy strength from the south in anticipation of a violent enemy reaction requiring defensive positions. Secondly, he was to move toward the Alban Hills for a link-up with the remainder of Fifth Army on D + 7. Clark became increasingly pessimistic about the British plan and the feasibility of the overall Anzio operation. The notion that the troops landing at Anzio could take and hold the Alban Hills so soon after the landing, as part of the British plan, seemed overly optimistic. Under the circumstances, the best that Clark could tell Lucas was to be flexible, leaving the decision about how far and how fast to move VI Corps up to him.
The landings at Anzio would be protected by Allied air and naval forces. There were approximately 2,600 Allied aircraft available to provide close air support for the invading forces and to destroy enemy airfields and hinder communications. The naval flotilla assigned to support the landings was designated Task Force 81, commanded by U.S. Rear Admiral Frank J. Lowry. The task force was made up of over 250 combat-loaded vessels and amphibious craft of all sizes and descriptions.
The German Forces in the Mediterranean were led by air force officer, Field Marshal Albert Kesselring who had arrived in Rome in December 1941. He had been a founding member of the Luftwaffe prior to receiving the rank of Field Marshal. The exact German reaction to the landing at Anzio was, of course, impossible to predict. The only thing that was known for certain was that the German response would be swift and brutal.
Start of the invasion
The Anzio invasion began at 2:00 A.M. on January 22, 1944, and achieved, General Lucas would recall, one of the most complete surprises in military history. The Germans had already sent their reserves south to counter the Allied attacks on the Garigliano River on January 18, leaving a nine- mile- wide stretch of the Anzio beach defended by a single company. The first waves of Allied troops moved rapidly inland. All VI Corps objectives had been taken by noon as Allied air forces flew 1,200 sorties in and around the beachhead. By midnight over 36,000 troops and 3,200 vehicles, over 90% of the invasion force, was ashore.
Allied units would continue to push over the next few days against scattered but increasing German resistance. Allied forces would capture the town of Aprilia on January 25. The Allied drive created a huge bulge in enemy lines but did not completely breakout of the beachhead. The Third Division commander, Major General Lucian Truscott, on orders from the corps commander, ordered a halt to the offensive which turned into a reorganization of the beachhead forces between January 26 and 29. During this time the materiel buildup would continue despite German air and artillery harassment. During this time the number of Allied troops on the beachhead increased to over 60,000.
In response to the landings, Kesselring would send elements of the 4th Parachute and Hermann Goering Divisions south from the Rome area to defend the roads leading north from the Alban Hills. Hitler would send additional forces from Yugoslavia, France, and Germany. By the end of D-Day thousands of German troops were converging on Anzio, despite delays caused by Allied air attacks. The German commanders were astonished that Allied forces had not taken immediate advantage of the unopposed landings.
General Lucas now planned a two-pronged attack for January 30. One to cut Highway 7 at Cisterna and the second was a move northeast up the Albano Road, break through the Campoleone salient, and exploit the gap by moving to the west and southwest. A link-up with Fifth Army in the south was still believed possible.
Driving forward?
The initial Allied attack on Cisterna would be carried out by Ranger Battalions under Colonel William O. Darby. Unknown to the Americans, their assault was aimed at the center of an area occupied by thirty-six enemy battalions massing for the February 1 counterattack.
The Rangers would get within 800 yards of Cisterna, when the Germans discovered the advancing lightly armed Rangers armed with only grenades and bazookas for anti-tank weapons. They attempted a fighting withdrawal but were mercilessly cut down. Of 767 men in the two battalions, only 6 would survive.
In spite of the disaster involving the Rangers, some progress was made by 3rd Division units against a much stronger enemy. But by nightfall on January 31, the Americans were still a mile from the village. It became apparent that the Americans were not going to capture Cisterna, and that new German units were arriving in the Anzio area. On orders from Clark and Lucas, Truscott was ordered to dig in.
The other prong of the Allied attack resulted in the Allies reaching Campoleone and penetrating the German main line. But the exhausted Allied troops were unable to exploit their success causing their drive to come to a halt, as a German counterattack began on February 3-4 at Campoleone salient. British forces held but were then ordered to retreat a distance of about 2.5 miles. Lucas then ordered Allied troops to form a beachhead defense line which was to be held at all costs. The Germans would continue their attack off and on until February 22. The offensive would be halted by Allied air power, naval gunfire, and artillery. The VI Corps would go over to the offensive and re-take some lost ground.
On February 29 the Germans resumed the offensive directed at the U.S. 3d Division in the Cisterna sector. General Truscott who had replaced General Lucas as VI Corps commander would substantially reinforce his defensive position. The Germans would continue to seek a breakthrough without any success. A final German assault would fail on March 4.
Following the collapse of the German drive, a three-month lull would begin. Both armies would limit their operations to defending the positions they held at the beginning of March. The VI Corps would reorganize and regroup bringing its full strength to 90,000 men in six divisions.
Supply problems at Anzio, originally one of the main concerns of the Allies would never reach a crisis point. LSTs would begin bringing loaded trucks to Anzio every day, fifteen smaller vessels arrived each week, and every ten days four massive Liberty Ships delivered heavy equipment. Between January 22 and June 1, over 531,511 long tons of supplies arrived at Anzio.
Operations in the spring
On May 5 General Clark would give General Truscott orders for a new Allied offensive code-named BUFFALO. Units from Anzio were to cut Highway 6, the main German line of retreat and trap the enemy forces retreating north through the Liri Valley. The operational concept had been dictated to Clark from Alexander, but Clark had little faith in the plan succeeding. Clark felt the British had received too much credit for Allied gains thus far. Clark wanted Fifth Army to have the honor of liberating Rome. He told Truscott to be ready at any moment during the breakout to swing north toward Rome.
On the night of May 11-12, Fifth and Eighth Armies launched their long- awaited attack against the Gustav Line but initially achieved little success. However, the Germans would abandon Monte Cassino after a week of fighting against Polish forces and the French along with US II Corps and would finally succeed in breaking the Gustav Line. The II Corps would move toward the Anzio beachhead against weakening German resistance.
At 0545 on May 23 an artillery barrage opened on the Cisterna front, followed by armor and infantry attacks along the entire line from Cassino to the Mussolini Canal. Although enemy resistance was very stiff, but by evening the Allied forces had breached the main line of resistance. The next day VI Corps forces cut Highway 7 above Cisterna. The town would fall on May 25. On the same day the II and VI Corps would complete their juncture causing the beachhead to cease to exist.
Meanwhile, the breakout in the west was proving very costly to the VI Corps, taking over 4,000 casualties in the first five days of the offensive. In the meantime, elements of Fifth Army joined in the pursuit of German forces falling back on Rome. American forces would liberate the Italian capital on June 4, 1944.
In perspective
The Anzio campaign has always been controversial from the time it was conceived. General Lucas had stated before the landing that he had always considered it a gamble. He maintained that under the circumstances the Anzio forces accomplished all that could have been realistically expected. However, some of Lucas’s critics maintain that a more aggressive commander such as Patton or Truscott could have obtained the goals of the landings with a bold offensive. Yet the campaign did achieve a number of goals including the eventual liberation of Rome.
