German occupation forces and Greek collaborator units surrounded the Athens neighborhood of Kokkinia at dawn on August 17, 1944, executing dozens of resistance members and arresting thousands of residents.
Nazi troops and Security Battalions ordered male residents between the ages of 15 and 60 to assemble at Osia Xeni Square early in the morning. Masked informants walked through the crowd, pointing out individuals suspected of supporting the anti-fascist resistance movement.
Those identified by the informers were immediately marched to a nearby disused carpet factory known as the Mantra of Kokkinia. Resistance fighter Dimitris Mavrakis recalled in a testimony recorded in Nasos Bratsos' book Labor Stories that anyone singled out by the masked men was taken straight to the wall to be shot. Firing squads executed approximately 75 people at the factory grounds, including several women.
Casualties and Hostages in Kokkinia
Additional summary executions occurred across the district as occupation forces searched homes and set residential buildings on fire. The exact total death toll for the day varies among historical sources. The Municipality of Nikaia-Agios Ioannis Rentis records approximately 300 victims killed across different locations in the city during the operation.
German forces arrested thousands of men during the raid and marched them to the Haidari concentration camp in western Athens. From Haidari, authorities later deported numerous prisoners to Nazi concentration camps and forced labor facilities inside Germany.
Kokkinia, which is known today as Nikaia, was a major working-class and refugee settlement established largely after the 1922 population exchange between Greece and Turkey. During the Axis occupation, the district became a key stronghold for the National Liberation Front, known as EAM. Five months prior to the blockade, in March 1944, heavy fighting broke out in the area between the Greek People's Liberation Army, known as ELAS, and German occupation troops alongside collaborating Greek units.
The Kokkinia Blockade remains documented as one of the bloodiest civilian roundups carried out in the Greek capital during World War II. The site of the Mantra carpet factory is preserved today as a permanent historical monument honoring the victims of the August 17, 1944 massacre.
