By late 1944, the "Luftwaffe" was suffering from such shortages of pilots, aircraft and fuel that serious air attacks could be discounted. As a result further cuts could be made in AA units to address the British reinforcement crisis. 91st Light Anti-Aircraft Regiment left 4th Division on 6 November, and while the rest of the division sailed for service against the uprising in Greece (the "Dekemvriana") on 12 December, 91st LAA Rgt was disbanded on 18 December 1944.
