Young Kimon sought an opportunity to reach the Middle East, and thus, joined Great Britain's 8th Army in North Africa who were fighting the Axis countries. In early June 1942, he got his chance when he assisted a group of SBS commandos carrying out the sabotage of the Kastelli Airfield. After the operation, he followed the British commandos to the Middle East where he fought in battles at El Alamein and Mersa Matruh. He later joined Force 133 and trained as a parachutist and saboteur. After returning to Crete in July 1943, he took part in the second sabotage against the Kastelli Airfield under the orders of Anders Lassen.
