A death march is when a group of people, which were typically Jewish prisoners from concentration camps, were forced to walk for long periods of time. If the prisoners could not keep up, they would get shot. Also to mention, they were forced to walk in the middle of the winter, with no food or water, and hardly any breaks, or none at all
This is what most people looked like during the marches
A lot of the prisoners who died were buried on the way
On the way to the death camps, often times prisoners were responsible for holding all materials the nazis needed.
