The Battle for Caen from June–August 1944 was a battle between Allied (primarily British and Canadian troops) and German forces during the Battle of Normandy. Originally, the Allies aimed to take the French city of Caen, one of the largest cities in Normandy, on D-Day. Caen was a vital objective for several reasons. Firstly, it lay astride the Orne River and Caen Canal; these two water obstacles could strengthen a German defensive position if not crossed. Secondly, Caen was a road hub; in German hands it would enable the enemy to shift forces rapidly. Thirdly, the area around Caen was relatively open, especially compared to the bocage country in the west of Normandy. This area was valued for airfield construction.
