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 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.

National and Social Liberation was a Greek Resistance movement during the Axis occupation of Greece. It was founded in autumn 1942 by Colonel Dimitrios Psarros and politician Georgios Kartalis.

Dimitrios Psarros was a Greek army officer, founder and leader of the resistance group National and Social Liberation (EKKA), the third-most significant organization of the Greek Resistance movement after the National Liberation Front (EAM) and the National Republican Greek League (EDES). In 1944, he was executed by Greek communist forces.
