Geoffrey Charles Castellain was born at Windlesham, Surrey on the 19th of February 1920 the only son of Ernest Frederick Castellain, a cotton broker, and Annie Ethel (nee James) Castellain of The Gale House, Fritham, near Lyndhurst in Hampshire. He was educated at Temple Grove School, Eastbourne and at Westminster School where he was admitted as a King’s Scholar and was up College from September 1933 to July 1938. He played the part of Crito in the school production of “Epilogus in Andriam in 1935. He was a member of the 2nd Rowing VIII in 1937 and 1938 where he rowed at No. 4 and was a member of the Officer Training Corps where he achieved Certificate A in March 1937 and was promoted to Lance Corporal in September 1936.
He matriculated for Christ Church, Oxford on a Classical Scholarship in 1938 and graduated with a 2nd Class in Classical Moderations in 1940. He attended the Royal Military College, Sandhurst from where he was commissioned as a 2nd Lieutenant in the 16/5th Lancers, Royal Armoured Corps on the 8th of March 1941. He transferred to the 2nd Special Air Service in April 1944 and was attached to A Squadron.
In September 1944, fifty one men of the 2nd Special Air Service were briefed for Operation Pistol. This was to involve the parachuting of four small teams into the Vosges Highlands, in the north of the Alsace-Lorraine area of France, where they were to disrupt road and rail communications between Metz and Nancy and on the approach to the Rhine Plain in support of the American advance in the area. They were to operate in an area roughly bounded by Saverne, Metz, Saarbrucken and Dieuze Due to the unsuitability of the terrain for forming a base of operations the men were to carry out their missions and then to find somewhere to lay up before making a next one. They were split into four groups, A, B, C and D and were to be dropped by parachute at four different drop zones. After landing, they were to split into smaller sub teams with each one being given a set of specific missions to achieve after which they were to head back towards the American lines in the west. Geoffrey Castellain would operate with B Group in the area of Sarreguemines.
The men took off from RAF Keevil in Stirling aircraft on the night of the 15th/16th of September 1944. One group was unable to jump due to thick fog but and, although B Group was able to jump from a height of 800 feet, they passed through low cloud and landed some seven miles from their drop zone.
When on the ground they split into their sub groups with Geoffrey Castellain leading sub group B2, which was made up of Corporal J. Laybourne, Private F. Wrobel, Private H.W.C. Arnold, Private J. Stainton and Private Christopher Ashe. Sub group B1 headed for the area of Ingwiller
B2 is known to have blown up a railway line near Sarreguemines
On the 2nd of October the men of B2 joined another SAS team who were part of an earlier operation code named Operation Loyton. Ten days later Geoffrey Castellain died of wounds. The rest of the group made their way to the American lines some time later.
Christopher Ashe had been captured by the Germans on the 23rd of September and was executed by them at Gaggenau on the 25th of November 1944.
Casualties for the operation had been four officers, five NCOs and five other ranks. When the Americans advanced through their area of operation they found one officer, one NCO and three other ranks from Operation Pistol still operating.
He is commemorated on the war memorial at Christ Church, Oxford and on the Special Air Service, SOE, GHQ Liaison Regiment war memorial at the National Arboretum.
He is buried at Moussey Churchyard, Grave 7.
