Nos.20, 21, 22 and 23 Squadrons

No.20 Squadron spent the entire Second World War in India and Burma, flying army co-operation and reconnaissance missions from 1942-February 1943 and ground attack missions for the rest of the war.
For most of the Second World War No.21 Squadron was a light bomber squadron, operating the Blenheim, Ventura and Mosquito, with a break from June 1940-March 1942 when it served as an anti-shipping unit with Coastal Command.
No.22 Squadron began the Second World War as a torpedo bomber of Coastal Command, before moving to the Far East in March-April 1942. After spending the next two years flying anti-submarine patrols and convoy escort missions, it converted to the Beaufighter and spent 1945 as a ground attack squadron in Burma.
No.23 Squadron spent the entire Second World War serving as a night fighter squadron, first in a defensive role, but from December 1940 as an intruder squadron, from bases in Britain and on Malta and Sardinia.
