RAF No 312 (Czechoslovak) Squadron

Motto: Non Multi Sed Multa (Not many men but many deeds)

Formed at Duxford on 29 August 1940 as a fighter unit composed of Czechoslovak personnel who had managed to escape from Nazi occupied Europe. Initially sent to Speke, with Hurricanes, as part of Liverpool's defences, it moved to Kenley in May 1941 from where it joined in offensive sweeps over the continent.

The squadron was formed at Duxford on 29 August 1940. It was crewed mostly by escaped Czechoslovak pilots, but its first commander was the British Squadron Leader Frank Tyson. On 12 September a Slovak fighter pilot, Ján Ambruš, was appointed as joint commander of the squadron. The plan was for responsibility to be transferred gradually from Tyson to Ambruš.

Initially the squadron was equipped with Hawker Hurricane Mk I fighters. On 26 September the squadron moved to RAF Speke to join the air defence of Merseyside. Its first victory was on 8 October 1940, when its Yellow Flight (Denys Gillam, Alois Vašátko and Josef Stehlík) shot down a Junkers Ju 88 medium bomber over Liverpool.

On 13 October Ambruš led a flight of three Hurricane Mk I fighters on patrol. Over the Irish Sea Ambruš mistakenly led the flight to attack two Bristol Blenheim Mk IF light bombers of No. 29 Squadron RAF. One Blenheim, L6637, code letters RO-S, crashed into the sea off Point of Ayre on the Isle of Man and not far from the Morecambe Bay light ship. All three of its crew were killed. The other Blenheim, L7135, code letters RO-S, survived with minor damage and returned safely to RAF Ternhill in Shropshire with its crew unharmed. Ambruš was relieved of his command, and on 12 December Sqn Ldr Evžen Čižek was appointed to succeed him. On 17 December Ambruš was transferred to the Inspectorate-General of the Czechoslovak Air Force in London.

On 3 March 1941 the squadron moved to RAF Valley on Anglesey and began flying convoy patrols over the Irish Sea. On 24 April the squadron moved to RAF Jurby, Isle of Man. In May 1941 the squadron was re-equipped with the Hurricane Mk II. On 27 May Sqn Ldr Jan Klán succeeded Čižek as commanding officer, and two days later the squadron moved to RAF Kenley in Surrey. Klán's tenure was brief, as he was replaced on 5 June with Sqn Ldr Alois Vašátko. On 20 July the squadron moved to RAF Martlesham Heath in Suffolk. On 19 August it moved again to RAF Heathfield in Ayrshire, Scotland.

The squadron was re-equipped with the Supermarine Spitfire Mk IIA in October 1941 and again with the Spitfire Mk VB/C in December. The squadron spent the first part of 1942 in Wales. It moved to RAF Fairwood Common in Glamorgan on 1 January, then to RAF Angle in Pembrokeshire on 20 February, and then returned to Fairwood Common on 10 April. The squadron's duties included coastal patrols and shipping reconnaissance flights.

On 23 June 1942 Sqn Ldr Vašátko was killed in action and Sqn Ldr Jan Čermák was appointed to succeed him. On 3 July 1942 the squadron moved to RAF Harrowbeer in Devon. On 19 August the squadron provided air cover for the Operation Jubilee raid on Dieppe. During the raid Miroslav Liškutín [cs] shot down a Dornier Do 217 bomber and 312 Squadron lost one of its own aircraft.

On 10 October 1942 the squadron moved to RAF Church Stanton in Somerset. On 1 January 1943 Sqn Ldr Tomáš Vybíral succeeded Čermák as squadron commander. On 24 June the squadron moved to RAF Skaebrae on Orkney. On 7 September the squadron moved to RAF Ibsley in Hampshire and joined the 2nd Tactical Air Force as a fighter-bomber unit. The squadron operated over France softening up targets in preparation for the invasion and then supporting the landings. On 1 November Sqn Ldr František Vancl succeeded Vybíral as squadron commander.

In January 1944 the squadron was re-equipped with the Spitfire Mk IX. From 20 February it spent a few days at RAF Mendlesham in Suffolk, before moving on 23 February to RAF Rochford in Essex.

On 3 April 1944 the squadron moved to RAF Appledram in West Sussex. From here its operations included intercepting V-1 flying bombs, escorting bombers and attacking rail and road targets in German-occupied Europe. On 15 May Sqn Ldr Jaroslav Hlad'o succeeded Vancl as squadron commander. On 22 June the squadron moved to nearby RAF Tangmere, also in West Sussex.

From 4 July 1944 the squadron spent a week at RAF Lympne in Kent. On 11 July it moved again to RAF Coltishall in Norfolk and operated daytime bomber escort flights over continental Europe. However, on 27 August its duties were switched to the Air Defence of Great Britain (ADGB), for which it was moved on RAF North Weald in Essex. On 3 October it moved again to RAF Bradwell Bay, also in Essex.

On 15 November 1944 Sqn Ldr Václav Šlouf succeeded Hlad'o as squadron commander. From 27 February to 8 June 1945 the squadron was based at RAF Manston in Kent.

Air Marshal Karel Janoušek can be seen behind him.

On 3 August members of all of the RAF's Czechoslovak squadrons held a farewell parade at RAF Manston. Air Marshal John Slessor inspected the parade, accompanied by Air Marshal Karel Janoušek. On 24 August 312 squadron moved to Ruzyně Airport in Prague. It became a squadron of the new Czechoslovak Air Force, and on 15 February 1946 was officially disbanded as an RAF squadron.

Seven Spitfire F Mk IXs survive today that flew with the squadron in 1944–45. This is by far the largest number of surviving aircraft associated with a single squadron.
