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. On D-Day, Caen was an objective for the British 3rd Infantry Division and remained the focal point for a series of battles throughout June, July and into August.
The battle did not go as planned for the Allies, instead dragging on for two months, because German forces devoted most of their reserves to holding Caen, particularly their badly needed armor reserves. As a result German forces facing the American invasion thrust further west were spread thin, relying on the rough terrain of the back country to slow down the American advance.
With so many German divisions held up defending Caen, the American forces were eventually able to break through to the south and east, threatening to encircle the German forces in Normandy from behind.
