Resumed bombardment of strategic targets in Germany and, except for support of the infantry during the Saint-Lô breakthrough on 25 July 1944. The squadron suffered very high losses of personnel and equipment while engaged in combat; combat losses leading to withdrawal of unit from operations in August 1944 after only 89 days of combat.
