One of two objectives of the movement, which was the military arm of the Unitary National Liberation Front (JNOF) coalition, led by the Communist Party of Yugoslavia (KPJ) and represented by the AVNOJ (Anti-Fascist Council of National Liberation of Yugoslavia), the Yugoslav wartime deliberative assembly, was fight against the occupying forces. The only source of supply was the enemy; for it was not until 1944 that British supplies began to arrive in appreciable quantities.
