Jasenovac concentration camp
Inmates were given rags and blankets, but they were very thin.  The barracks were also not enough to keep inmates warm from the cold.  Prisoners' clothes and blankets were rarely cleaned.  Inmates were allowed to wash them quickly in the lake once a month, except during the winter, when the lake froze.  Then, inmates were sometimes allowed to boil a few clothes, but not well enough to get them clean.
