Close

Initial attempts to penetrate the defenses before they had been effectively manned had failed and a set piece, prepared assault became necessary. The action was hard-fought and the Germans launched repeated counterattacks over the two days, attempting to retake their former positions. Ultimately, Allied forces of the 1st Canadian Division, 5th Canadian Armoured Division and II Polish Corps penetrated the Hitler line and the German defenders had to retreat, in some disorder.^[5] A corresponding same-day American breakout at the Anzio beachhead further weakened the German situation in Italy.
