From 1943 the city was bombarded by Allied aircraft. While the First World War had not notably damaged the city, Anglo-American bombing caused extensive destruction in raids of which at least one was allegedly carried out by mistake. In August 1944, several buildings in the Old Town were damaged by bombs, particularly the Palais Rohan, the Old Customs House ("Ancienne Douane") and the Cathedral. On 23 November 1944, the city was officially liberated by the 2nd French Armoured Division under General Leclerc. He achieved the oath that he made with his soldiers, after the decisive Capture of Kufra. With the Oath of Kuffra, they swore to keep up the fight until the French flag flew over the Cathedral of Strasbourg.
