Operation Windsor (4–5 July 1944), was a Canadian attack, which was part of the Battle of Normandy during the Second World War. The attack was undertaken by the 3rd Canadian Infantry Division to take Carpiquet and the adjacent airfield, from troops of the 12th SS-Panzer Division Hitler Jugend of Panzergruppe West. The attack was originally intended to take place during the later stages of Operation Epsom, to protect the eastern flank of the main assault but was postponed for a week.
