The fact that during WW2 several units of foreign soldiers and combatants fighted against the Allies alongside the Italian Army - both before and after the fall of Mussolini on July 25th and the later constitution of the Italian Social Republic allied to the Germans - shouldn’t be a surprise for anyone. Some historian has even written about a Mussolini’s “foreign legion”. In fact there was the (failed) attempt to give life to an Indian legion, made up of hindu nationalists, mainly enlisted within the ranks of the British troops taken prisoner in North Africa and to do the same with Arab nationalists.
