Arthur Brown joined the army in 1943 as a radio operator in the Tank Regiment but soon became fed up with the training and volunteered for the Special Operations Executive (SOE). He joined Operation Jedburgh, which involved three-man teams—an allied commanding officer, a radio operator, and a local officer—being parachuted behind enemy lines around D-Day to work with resistance fighters in France and the Low Countries. There were around 100 ‘Jedburgh’ teams deployed in the European theatre mainly between June and September 1944. On the 9th of June, Brown, now a Sergeant, his team leader, the highly decorated Scottish officer, Major Tommy MacPherson and a French officer, Michel ‘Bourbon’ were dropped into central France to assist the Maquis. The ‘Jedburgh’s were dressed in military uniform to avoid being executed as spies, if captured. Brown’s role was to send coded radio messages back to the UK updating their operations but he became ill and had to be hidden by the Maquis, being moved around to avoid detection. After France was liberated, he and MacPherson continued similar operations in Italy until the German surrender. When faced with a possible posting to Germany, Brown volunteered to go to Burma and served there with other former ‘Jedburghs’ until the war's end. 

Davies joined the Territorial Army as a teenager just before the Second World War and became a regular soon after, obtaining an officer’s commission in 1941 and joining the Commandos, following his older brother. Davies took part in the allied invasion of North Africa in November 1942 and landed by beach behind German lines in Tunisia to assist in a planned allied attack of the town of Bizerte. The Commandos came under intense fire, suffering casualties, including his own troop commander who was fatally shot. Davies eventually lead his own section back to allied lines where they joined the successful allied push against the Germans. Soon after Davies returned to England for training before being sent to the Far East. In January 1945, Davies, now with 5 Commando landed on the Myebon Peninsula in Burma and took part in the taking of Hill 170 at Kangaw, a desperate battle that lasted 36 hours and which led to the withdrawal of the Japanese Army from the Arakan. Whilst planning for the invasion of Malaya, the war ended and Davies then went to Hong Kong and Shanghai, where he assisted in repatriating British men and women interned by the Japanese. Davies was demobbed in May 1946.
