Bernard Montgomery helped reshape the Overlord assault plan and commanded the 21st Army Group during the Normandy campaign. British and Canadian armies operated under his ground command during the initial campaign.
Montgomery's strategy emphasized securing and expanding the lodgement while drawing German armour toward the eastern sector. His conduct of the campaign remains central to debates over Allied operational planning in Normandy.
