Army Group B
The Battle of Chambois was an August 1944 battle during the Battle of Normandy in World War II. Prior to the battle, a pocket had formed around Falaise, Calvados, where the German Army Group B, with the 7th Army and the Fifth Panzer Army (formerly ) were encircled by the Western Allies. The seizure of Chambois by American, Canadian and Polish forces saw the final closure of the Falaise Pocket on August 21, 1944 and the destruction of most of Army Group B.
