No. 605 Squadron (RAF): Second World War

Aircraft - Locations - Group and Duty - Books

No.605 (County of Warwick) Squadron went through two incarnations during the Second World War, first as a fighter squadron that took part in the Battle of Britain before being destroyed during the early part of the war in the Pacific in 1942 and second as a home-based intruder squadron.

Like most of the Auxiliary Air Force No.605 was formed as a day bomber squadron, but became a fighter squadron in 1939. It was initially given Gloster Gladiators, but began to convert to the Hurricane just before the start of the Second World War. On the first day of the war the squadron had six Hurricanes and ten Gladiators, but the biplanes were all gone before serious fighting began. The squadron began the war at Tangmere. It moved to Scotland in February 1940, and remained there until September, apart from one week in May 1940, when the squadron moved south to fly patrols over northern France.

15 August saw the heaviest fighting of the entire Battle of Britain, when the Luftwaffe attempted to bring Luftflotte 5 in Norway and Denmark into the battle. No.605 Squadron was one of five fighter squadrons based in the north-east that intercepted this force and prevented it from doing any damage and inflicted such heavy losses on the Germans that they didn't make another daylight attack from Scandinavia during the Battle of Britain.

On 7 September 1940 the squadron moved to Croydon (No.11 Group), and remained there for the rest of the year. It thus took part in the fourth phase of the Battle of Britain (the daylight raids on London) and the final fighter-bomber phase.

From December 1940 the squadron provided fighter escorts for bombers operating over northern France. It moved to the Midlands to provide defensive cover in March, and remained there until it was posted overseas in October 1941.

The squadron was soon caught up in the disastrous first months of the war in the Far East. It arrived at Singapore in January 1942 and was almost immediate evacuated to Sumatra.

The squadron was involved in the Allied evacuation from Sumatra to Java. In February 1942 a party of fifty volunteers from the squadron returned to the port of Oesthaven on H.M.A.S. Ballarat and spent twelve hours retrieving some invaluable equipment that had been left behind when the port was evacuated two days earlier.

More normal duties followed, and from 17-27 February the squadron took part in the air defence of Batavia, alongside No.232 Squadron. By 28 February the two squadrons were at less than half strength and it was decided to keep No.232. Volunteers from No.605 filled the gaps in that squadron and the rest of the squadron was evacuated. No.605 ceased to exist in March.

The squadron appears to have been split in two during its trip to the Far East. A detachment from the squadron is recorded as having operated from Hal Far, Malta, from 10 January-27 February 1942.

No.605 Squadron reformed at Ford on 7 June 1942. This time it was formed as an intruder squadron, initially equipped with the Boston. Operations began on 14 July 1942, and the squadron was used to interrupt German operations in France, lingering over Luftwaffe airfields. In February 1943 the Bostons were replaced with the much more capable Mosquito. Intruder missions continued until the end of the war. The squadron moved to Belgium in March 1945, and to the Netherlands in April.

On 31 August 1945 No.605 was renumbered as No.4 Squadron. A new No.605 Squadron was formed in the Auxiliary Air Force in May 1946.
