EDES
ELAS became the strongest of all resistance armed organizations, controlling by 1944 military three-fifths of the country (mainly the mountains) having in its ranks more than 800 military officers of the former National Army. ELAS engaged in battles against other resistance groups, besides the para-military forces of the collaborationist government. ELAS initially began to attack the National Republican Greek League (EDES) on accusations of collaboration with the Germans. ELAS attacked also the Panhellenic Liberation Organization (PAO), another resistance organization, concentrated in Northern Greece, in the area of Macedonia with accusations of collaboration. The armed power of the two major organizations was not comparable, as EDES had approx. 12,000 guerrillas, while ELAS' power was much stronger. Small battles were taking place in Epirus where EDES had its main force. This situation led to triangular battles among ELAS, EDES and the Germans. Given the support of the British and the Greek Cairo Government for EDES, these conflicts precipitated a civil war.
