General Bernard Montgomery’s “armoured blitzkrieg,” Operation Goodwood, and its Canadian component, Operation Atlantic, ended in rain and confusion on July 20, 1944. The next day, Montgomery and his army commander, Lieutenant-General Sir Miles Dempsey, met to consider their options. News of the failed assassination attempt against Hitler was discussed as was the postponement of Operation Cobra, the major American offensive originally scheduled for July 20. The two British generals agreed they could not wait for the Americans; they would launch their attack south of Caen as soon as possible.
