The World War 1 Siege Turned Living Nightmare... (Attack of the Dead Men)

The World War 1 Siege Turned Living Nightmare... (Attack of the Dead Men) In this video, DaleyTactics tells the story of the WW1 siege of Osowiec Fortress and the attack of the dead men after brutal German Army chemical warfare. This is all real history and I guess sort of true crime? idk.
