Ravensbrück concentration camp
Towards the end of World War II, the camp was so crowded that 1,500 to 2,000 women were packed into barracks meant to hold only 250 people.  Many women had to sleep on the floor, without even a blanket.  In 1945, the barracks were so crowded and sanitation was so bad that an epidemic of typhus spread through the camp.  The disease killed many prisoners.
