Forces of the Communist-controlled Greek People's Liberation Army attack the smaller National and Social Liberation resistance group, which surrenders. Its leader Dimitrios Psarros is murdered.

The Greek People's Liberation Army, known mostly by its acronym ELAS, was the military arm of the left-wing National Liberation Front (EAM) during the period of the Greek resistance until February 1945, when, following the Dekemvriana clashes and the Varkiza Agreement, it was disarmed and disbanded. ELAS was the largest and most significant of the military organizations of the Greek resistance.
