Operation Charnwood was a Second World War Anglo-Canadian offensive that took place from 8 to 9 July 1944, during the Battle of Normandy. The operation was intended to at least partially capture the German-occupied French city of Caen (French pronunciation: [kɑ̃]), which was an important Allied objective during the opening stages of Operation Overlord. It was also hoped that the attack would forestall the transfer of German armoured units from the Anglo-Canadian sector to the lightly screened American sector, where a major US offensive was being planned. The British and Canadians advanced on a broad front and by the evening of the second day had taken Caen up to the Orne and Odon rivers.
