Born in 1917 in Fredensborg, Denmark, Sven Hassel joined the merchant navy at the age of 14. He did his compulsory year's military service in the Danish forces in 1936 and then, facing unemployment, joined the German army. He served throughout World War II on all fronts except North Africa. When the war ended in 1945 he was transferred between Russian, American and French prison camps, and upon returning to Denmark, was sentenced to 10 years in prison for treason. He began writing LEGION OF THE DAMNED during his time as a prisoner of war. His fourteen World War II books, which draw on his own encounters and experiences as a soldier, have sold over 53 million copies worldwide and have been published in more than 50 countries. He peacefully passed away in Barcelona in 2012, where he had resided since 1964.
