Impressed by the success of German airborne operations, during the Battle of France, the British Prime Minister, Winston Churchill, directed the War Office to investigate the possibility of creating a corps of 5,000 parachute troops. On 22 June 1940, No. 2 Commando was turned over to parachute duties and on 21 November, re-designated the 11th Special Air Service Battalion, with a parachute and glider wing. It was these men who took part in the first British airborne operation, Operation Colossus, on 10 February 1941. In September, the battalion was re-designated the 1st Parachute Battalion and assigned to the 1st Parachute Brigade. To fill out the brigade, the 2nd, 3rd and 4th Parachute Battalions were raised by calling for volunteers from all units in the British Army.
