Allied offensives focused on Cherbourg and Caen.
The 9th, 79th, and 4th Infantry Divisions battled their way through formidable fortifications and fierce resistance to seize Cherbourg.
The port itself fell on the 27th, and residual resistance had been mopped up by the end of the month.
Meanwhile, the 1st, 2nd, 29th, 30th and 90th Infantry Divisions and the 82nd and 101st Airborne Divisions sustained aggressive defenses in their sectors, protecting the rear of the attack on Cherbourg, furthering the attrition of the Germans, and covering the build-up for the breakout offensive.
The 2nd Armored Division continued as a mobile reserve, dispatching reinforcements to divisions in the line as necessary.
The 3rd Armored Division and 83rd Infantry Divisions arrived and deployed, with the 83rd replacing the 101st at Carentan.
Commonwealth attacks near Caen drew off the lion’s share of German armored forces and forced them to deploy piecemeal rather than make concerted counter-attacks.
