Squadron Leader LH Buck Casson DFC, AFC:

Coming from Sheffield Lionel H Casson was one of the original volunteer pilots to join 616 (South Yorkshire) Auxiliary Air Force Squadron on its formation at Doncaster in 1938. After pilot training, he served briefly with 79 Squadron flying Hurricanes from Biggin Hill before rejoining Spitfire equipped 616 at Leconfield in July 1940. With the squadron he flew south to Kenley in mid-August and over the next three weeks was involved in fierce fighting during the Battle of Britain. On 30th August he was credited with a probable and a damaged HE111. Two days later he claimed a Bf109 followed by the destruction of a Do17. After suffering severe losses, the squadron was withdrawn to Kirton-in-Lindsay on 4th September and after a rest period, 616 moved to Tangmere in February to join the 'Bader Wing'. On 5th May 1941, Casson shared in the destruction of a Ju88 but was hit by return fire and was forced to bale out. Flying on daily sweeps and bomber escorts over Northern France, he destroyed a Bf109 on 22nd June and he claimed a damaged two days later. He was made Flight Commander in July and claimed two Bf109s as probables. On 9th August as he was leading his flight over St Omer, his aircraft was hit and he was forced to crash land. He was soon captured and spent the rest of the war in the infamous Stalag Luft 3. Shortly after his capture he was awarded the DFC. After his release four years later, he rejoined the peacetime 616 Squadron, equipped at first with Mosquito night fighters and then Meteor jet fighters. He was appointed as Commanding Officer in December 1950 during which time the Squadron won the coveted Esher Trophy awarded to the top Auxiliary Air Force squadron. After three years in command, he retired having been awarded the AFC for his outstanding leadership.

616 squadron was formed at Doncaster on 1st November 1938 as the last of the Auxiliary Squadrons. Formed initially as a bomber squadron equipped with Hawker Hinds, it was re-equipped with Gloster Gauntlets in June 1939 and transferred to Fighter Command. The squadron's first Spitfires arrived in late October. 616 first saw action and claimed its first victories whilst covering the evacuation from Dunkirk in May 1940. Returning to Yorkshire, the squadron claimed further enemy victims with 15th August standing out as a memorable day. 616 intercepted a large force of unescorted German bombers off the Yorkshire coast and claimed eight enemy aircraft destroyed. They moved to Kenley to join 11 Group at the height of the Battle of Britain, and destroyed 15 aircraft and claimed a further 15 as probables or damaged. During February 1941, 616 joined the Tangmere Wing led by Wg Cdr Douglas Bader. Flying Spitfire II fighters, they flew 'circus' and 'ramrod' sweeps over Northern France, and re-equipped with Spitfires Vb during July 1941. For the next two years 616 continued as a front line fighter squadron and was heavily engaged during the Dieppe expedition and later flying beach-head patrols on D-Day. In July 1944, 616 re-equipped with Gloster Meteor jet fighter thus becoming the first and only Allied squadron to operate jet aircraft in World War II. The squadron destroyed a number of V1 flying bombs whilst operating from Manston before joining the 2nd Tactical Air Force. In January 1945, 616 moved to the continent and operated in the ground attack role before being disbanded at Lubeck on 29th August. The squadron was re-formed at Finningley on 31st July 1946 equipped with Mosquito NF XXX night fighters which were replaced with Meteor F 3 day fighters a few months later. 616 Squadron Royal Auxiliary Air Force was finally disbanded at RAF Worksop on 10th March 1957 whilst equipped with Meteor F8 aircraft.
