The Nazi doctors would puncture the women with shards of unbroken glass, to deliberately infect them
FOUR brave Nazi death camp prisoners exposed the evil experiments they were subjected to using coded letters filled with urine.
Krystyna Czyz, Wanda Wijtasik, Janina Iwaska, and her sister Krystyna Iwaska were part of 74 "test rabbits" who endured twisted medical tests in the Ravensbruck concentration camp.
Physicians including Karl Gebhardt, the personal doctor to SS leader Heinrich Himmler camp in northern Germany who led the camp, would drag the inmates into their laboratories.
The Nazi doctors would puncture the women with shards of unbroken glass, in a bid to give them an infection.
Ms Czyz was just 15 years old when her hometown of Lublin was invaded by the Nazi's in September 1939.
After her family were ferociously interrogated, she was taken to the lab along with dozens of other women.
'TEST RABBITS'
During their time, they were only allowed to send one letter to their families each month, and officials would monitor what was within them.
But between 1943 and 1944 the women became fed up and sent 27 letters to their families, to highlight the abuse they were enduring.
The notes, revealed in book, , by Dr David Gill, were filled with clues and hints, and also included urine, to stop it being decoded.
