About Lt Hartmeister;

OSS/SO operatives that had been stationed in various parts of Greece throughout 1944 confirmed assessments repeatedly in their final reports to Cairo….

Lt. Joel Hartmeister, was a former airman shot down over Greece and recruited into the OSS by Woodhouse and Wines, eventually ended up working as
the American liaison in western Thessaly. In his final report he questioned the Allied wartime commitment to EAM/ELAS. "My feelings are that we have
created a more or less Frankenstein monster in Greece which will make demands and be difficult to bargain with in the future. The guns and ammunition
that has [sic] been supplied to the andartes [guerillas] will never be given over to any other force."
