With
World War II interrupting his studies, Fraser joined the
Seaforth Highlanders,
British Army in 1941. He was
commissioned as a
second lieutenant on 16 August 1941, having attended an Officer Cadet Training Unit. He was given the
service number 201494. It was because of his knowledge and interest in Classical Greece, that he was recruited by the
Special Operations Executive. Between 1943 and 1945, he was involved in the British Military Mission to
Axis occupied Greece. On 12 July 1943, he parachuted into Greece near the town of
Kalamata. He gradually moved through the
Peloponnese to the
Argolis and Corinthia Prefecture. There he spent the winter of 1943 and the spring of 1944. His mission was to arm and assist the 'officer bands', the non-communist
guerilla groups. However, the pre-existing structure of the
Greek People's Liberation Army meant that by October 1943 only the communist resistance were strong enough to continue the fight against the occupiers. Fraser described his relationship with the
EAM-ELAS as "the worst, since my original mission in that area was to try to find and, having found, to arm non-ELAS '
andartes' ". In 1944, he led a raid on a Nazi
airfield near
Argos, resulting in its successful destruction. By the end of the war, he was effectively the commander of
Volos. ==Academic career==
