22 January-24 May 1944

During the early morning hours of 22 January 1944, troops of the Fifth Army swarmed ashore on a fifteen-mile stretch of Italian beach near the prewar resort towns of Anzio and Nettuno. The landings were carried out so flawlessly and German resistance was so light that British and American units gained their first day's objectives by noon, moving three to four miles inland by nightfall. The ease of the landing and the swift advance were noted by one paratrooper of the 504th Parachute Infantry Regiment, 82d Airborne Division, who recalled that D-day at Anzio was sunny and warm, making it very hard to believe that a war was going on and that he was in the middle of it.

The location of the Allied landings, thirty miles south of Rome and fifty-five miles northwest of the main line of resistance running from Minturno on the Tyrrhenian Sea to Ortona on the Adriatic, surprised local German commanders, who had been assured by their superiors that an amphibious assault would not take place during January or February. Thus when the landing occurred the Germans were unprepared to react offensively. Within a week, however, as Allied troops consolidated their positions and prepared to break out of the beachhead, the Germans gathered troops to eliminate what Adolf Hitler called the 'Anzio abscess.' The next four months would see some of the most savage fighting of World War II.
