No.501 ‘County of Gloucester’ Squadron was a fighter squadron that was originally formed as part of the Special Reserve in 1929, and that took part in the Battle of Britain, the period of offensive sweeps over occupied Europe and the anti V-1 campaign.

The squadron was formed on 14 June 1929 as No.501 ‘City of Bristol’ Squadron, and was equipped with D.H.9A day bombers. The squadron remained a day bomber unit for most of the 1930s, converted to the Wapiti, Wallace, Hart and Hind in turn. In May 1936 the squadron became part of the Auxiliary Air Force, and its name was changed to ‘County of Gloucester’ Squadron to more accurately reflect the origins of its part time personnel.

At the end of 1938 the squadron was converted into a single seat fighter squadron, receiving its Hawker Hurricanes in March 1939. After the outbreak of the Second World War the squadron remained in Britain, flying defensive patrols. After the start of the German offensive in the west in May 1940 the squadron joined the AASF in France, and took part in the retreat across France to Brittany, ending up at Dinard from 11-18 June, before retreating to Jersey and then back to the south of England.

No.501 Squadron was based in the south of England throughout the Battle of Britain. It was at Middle Wallop (No.10 Group) for most of the initial period of convoy battles, but moved to Gravesend, a satellite station of Biggin Hill on 25 July. The squadron remained at Gravesend throughout the hardest fighting of the battle. On 15 August, one of the hardest days of the battle, the squadron was one of four that disrupted the first German attack of the battle. It remained at Gravesend during the assault on Fighter Command. On 10 September, just after the start of the daylight attack on London, the squadron finally moved, but only to the Sector Station at Kenley, where it remained until mid-December. 

The squadron began flying offensive sweeps over France early in 1941, still using its Hurricanes. Spitfires arrived in April 1941, and were used for offensive sweeps for the rest of 1941 and most of 1942. The squadron moved to Northern Ireland for a rest from October 1942 until April 1943, before returning to the south of England, where it spent the rest of the war.

In July 1944 the squadron converted to the Hawker Tempest. In August 1944 pilots from the Fighter Interception Unit joined the squadron. This unit had been involved in developing methods for catching V-1 flying bombs at night, and the squadron took part in the anti V-1 campaign until September, when the Allied armies captured the last V-1 launching areas.

The Germans responded by launching V-1s from bombers operating over the North Sea. No.501 Squadron moved to East Anglia, where it flew a mix of defensive patrols aimed at these bombers and escort missions for Bomber Command’s daylight bombers. By March 1945 the squadron had shot down at least 88 V-1s.

The squadron was disbanded on 20 April 1945, but was reformed as part of the post-war Auxiliary Air Force in May 1946, still as a fighter squadron.
