Wilfred Greville Clouston DFC (15 January 1916 – 24 May 1980) was a New Zealand flying ace of the Royal Air Force (RAF) during the Second World War.

At the time, the squadron was based at Duxford and operated the Gloster Gauntlet but in August the following year, it began to re-equip with the Supermarine Spitfire.

Its operational role was to protect shipping in the North Sea by flying covering missions for convoys but generally it saw little offensive action by the Germans.

[4][7] The intensity of operations increased towards the end of the month as the bulk of the British Expeditionary Force (BEF) withdrew to the area around Dunkirk and the RAF fighter squadrons provided aerial cover for the trapped troops.

[11] Later in the month, he was awarded the Distinguished Flying Cross (DFC) for his efforts; the citation published in The London Gazette read: During recent operations over France and Belgium, Flight Lieutenant Clouston shot down four enemy aircraft.

[13][14] In June the squadron took delivery of some Spitfires that were experimentally fitted with Hispano cannons but these proved problematic and were prone to jamming.

[15] As the Battle of Britain escalated, the squadron was one of those that formed the Duxford Wing and were scrambled on several occasions in August to protect the airfields of No.

On 9 August, while flying a cannon-equipped Spitfire, Clouston was credited with half shares in two Bf 109s shot down over the Thames Estuary.

When the British fighters attacked, the bombers scattered and Clouston, leading a section of his flight, spotted a group of Do 17s and managed to destroy one.

It began its operational service flying cover for convoys along the north-east coast but soon shifted to Jurby, in the Isle of Man.

From Jurby it flew patrols to target German bombers attacking the ports along the English north east coast.

[20] On one of these operations, accompanying Bristol Blenheims raiding a petroleum plant in Gosnay, Clouston was wounded when his Hurricane was attacked by a Bf 109.

His flight commanders were in Singapore ten days later and together they greeted the rest of the squadron when it arrived from New Zealand on board the SS Tasman on 10 October.

[27] Despite this, he set about bringing the squadron up to operational readiness as soon as possible but his time was largely taken up with administrative matters and his flight commanders did much of the flying training.

By the end of the year it was flying regular patrols aimed at detecting and destroying Japanese reconnaissance aircraft but the Buffaloes were inadequate for the task, having a low operational ceiling.

[30] On 23 January 1942, Clouston was posted to RAF headquarters at Singapore, working in the operations room, with John MacKenzie, one of the squadron's flight commanders, taking over responsibility for No.

[30][31] During the final days of the Battle of Singapore, with the squadron's pilots having already been evacuated, its ground crew worked to prepare a Hawker Hurricane for Clouston's use in the event he wanted to escape.

[34] Before his capture, he was able to facilitate the evacuation of the remaining ground crew of the squadron from Singapore, obtaining spaces for them aboard the Empire Star when it sailed on 12 February.

[33][35] Clouston was interned for most of the war at a POW camp at Palembang in Sumatra but by the time of the Japanese surrender in September 1945, he was held at Changi Prison back on Singapore.

The effects of his internment as a prisoner of war saw his health decline rapidly in his later years and his son took over the running of his farm, named Tangmere after the RAF station, while Clouston moved to town.
