As Soviet armies advanced in 1944 and early 1945, Nazi soldiers gradually evacuated Auschwitz. On January 18th, officers sent some 60,000 prisoners in “good” health, on what became known as “death marches“, to other concentration camps away from the front. Some 15,000 prisoners died on that journey.

Some few thousand prisoners too sick to walk remained at the camp and were found by arriving Soviet troops on this day in 1945.

Other notable events on January 27th:
