Operation Goodwood was an offensive operation by the British Army against the German Wehrmacht, which took place between 18 and 20 July 1944 as part of the larger battle for Caen in Normandy, France during the Second World War. While Goodwood failed in its primary aim, it forced the Germans to keep powerful formations opposite the British and Canadians on the eastern flank of the Normandy beachhead and Operation Cobra, the First US Army attack which began on 25 July, caused the weaker German defences opposite to collapse.
