Previously unpublished documents from the Imperial War Museum have prompted new research into the story of a Hungarian Jewish refugee - who was living in Guernsey at the start of the Occupation.
Historian and archaeologist, Dr Gilly Carr has spent more than a decade studying the Channel Islands.

Julia Brichta came to Guernsey in 1939, one year before the arrival of German forces.
After being taken to Ravensbrück, a concentration camp for women in Germany, she became a camp police officer.
There was doubt surrounding the story, with some historians claiming she could not be believed.
