Falaise pocket
The Falaise pocket was considered closed by the evening of 21 August. Tanks of the Canadian 4th Armoured Division had linked up with the Polish forces in Coudehard, and the Canadian 3rd and 4th Infantry Divisions had fully secured St. Lambert and the northern passage to Chambois. Both Reynolds and McGilvray place the Polish losses on the "Maczuga" (Polish:bludgeon club cudgel) at 351 killed and wounded and 11 tanks lost, although Jarymowycz gives higher figures of 325 killed, 1,002 wounded, and 114 missing—approximately 20% of the division's combat strength. For the entire operation to close the Falaise pocket, Copp quotes from the 1st Polish Armoured Division's operational report, citing 1,441 casualties including 466 killed in action. McGilvray estimates the German losses in their assaults on the ridge as around 500 dead with a further 1,000 taken prisoner, most of these from the 12th SS Panzer Division. He also records "scores" of Tiger, Panther and Panzer IV tanks destroyed, as well as a significant quantity of artillery pieces.
