Falaise pocket
By the evening of 21 August, tanks of the 4th Canadian Armoured Division had linked with Polish forces at Coudehard, and the 2nd and 3rd Canadian Infantry divisions had secured St. Lambert and the northern passage to Chambois; the Falaise pocket had been sealed. Approximately 20–50,000 German troops, minus heavy equipment, escaped through the gap and were reorganized and rearmed, in time to slow the Allied advance into the Netherlands and Germany.
