REASON FOR LOSS:
Taking off at 20:17 hrs on a 'Gardening' operation in the Königsberg (Kaliningrad) area. A return trip of almost 1,790 miles they were flying at the maximum range of the Lancaster. 41 aircraft taking part in the operation.

LM278 was hit by flak and crashed at 01:13 hrs near Pokarben 4 km east of Brandenburg. Six of the crew were KiA and Sgt. Souci became a PoW.
Post war (1949) the Missing Research Enquiry Team were prevented access to identify and relocate the graves as the area as this was then in the Russian zone. It is known that the crew were buried at 20:30 hrs on the 19th August 1944 at the Frisches Haff, Brandenburg Cemetery (now known as Ushakavo). German documents had the details of the burial, including a map shown below:

(1) Flt Lt. Clark was awarded the Distinguished Flying Cross (DFC) whilst with 57 Squadron. Promulgated in the London Gazette on the 12th February 1946.
Citation Reads: ‘Flt Lt. Clark has taken part in may operations sorties which have included attacks against targets located in the most heavily defended areas in Germany and enemy occupied territory. On one occasion in July 1944 he was captain of an aircraft detailed to attack St Leu Desserant. When 25 miles from the target one engine of his aircraft was hit by anti-aircraft fire. Fire broke out but was extinguished and the target successfully attacked. Shortly after leaving the target another engine became unserviceable. The aircraft was illuminated by searchlights and heavily attacked by enemy ground defences. Largely owing to this officer’s skilful handling it escaped further damage and although the hydraulic system shot away a forced landing was safely accomplished at base. Flt Lt. Clark displayed cool courage and fortitude in continuing to his target in such hazardous circumstances. At all times his devotion to duty and determination have been worthy of the highest praise’.
(2) Sgt. Souci was interrogated immediately after being captured in Königsberg.
He was then transferred to the Reserve Lazarett (hospital) at Hohemark, Dulag Luft, Oberursel arriving there on the 4th September 1944, for treatment for unknown injuries.
On the 10th September 1944 he was transferred to the Obermassfeld Hospital #1249 for further treatment and where he remained until the 30th September.
Obermassfeld Hospital #1249 also known as Reserve-Lazarett 9C(a) (Served Stalag 9C) Obermassfeld Thuringia, Germany
He was then transferred to the Reserve Military Hospital 9C(b) at Meiningen where he remained until the 26th October 1944 when he was deemed fit enough to be transferred to Stalag Luft 7 at Bankau, arriving there on the 29th October 1944.
On the 19th January 1945, he was amongst the 1,500 prisoners marched out of the camp in the bitter cold. They crossed a bridge over the river Oderon the 21st January, reached Goldberg on 5th February, and were loaded onto a train.
On the 8th February they reached Stalag 3Alocated about 52 km (32 mls) south of Berlinnear Luckenwalde, which already held 20,000 prisoners, consisting mainly of soldiers from Britain, Canada, the US and Russia.
On the 22nd April 1945 as the Russians approached the camp the guards fled leaving the prisoners to be liberated by the Red Army.
Stalag 3A was turned over to the Americans on the 6th May at which time the Senior American Officers (SAO) took over the running of the camp until all the PoWs were evacuated. He remained there until the 20th May 1945 when he was evacuated. He was Interviewed on the 24th May 1945.
Henry Souci was born on the 16th September 1916 in Mauritius. He was a Civil Servant prior to enlisting in the RAFVR on the 21st May 1942.
