After the failed Italian attack against Greece, the Greek forces counterattacked and penetrated deep into Italian held Albanian territory, however, with the German intervention in April 1941, Greece capitulated. By April 15,1941, the Royal Hellenic Air Force was virtually eliminated by the numerically and technically superior German Luftwaffe, part of the Greek air force personnel managed to escape to Egypt together with five Avro Anson aircraft. These aircraft formed the 13th Light Bomber Squadron during the summer of 1941, during the following months two additional Greek squadrons were founded, the 335th and 336th Pursuit Squadrons. Its first mission was assigned on July 14,1941, at December 1941 the Squadron was equipped with Bristol Blenheims Mk IV and based at Dekheila Airfield. The following months it was reequipped with Blenheims Mk V, which were used primarily for patrol missions. Convoy escort and anti-submarine patrols were the missions of the Squadron during 1942. In various occasions enemy submarines were spotted in the Eastern Mediterranean, from early 1943 the Squadron operated with Martin Baltimores. Apart from anti-submarine patrols and convoy escorts, the Squadron also executed reconnaissance, at November 12, the fortified German positions at the port of Souda, in Crete, were bombed.
