in the picture below, A man is about to be shot and killed by a nazi soldier.
This furnace is where many prisoners of the camps were burned to ashes.
Several people were mercilessly burned by nazi soldiers in furnaces, such as the one above.
Thousands of people were forced to dig deep holes in the ground, then, unexpectedly, they were shot and killed. the dead fell in the hole that the person dug and the hole became his/her grave. another prisoner had to bury the dead body... People practically dug their own graves...
