It was calculated that about 600,000 Italian soldiers were captured between 1915 and 1918. About half were captured during the Twelfth Battle of the Isonzo, also called the Battle of Caporetto, which took place from 24 October to 17 November 1917. The majority were deported to Mauthausen (Austria), Theresienstadt (Bohemia, now in the Czech Republic), Rastatt (southern Germany) and Celle (near Hanover in northern Germany).
