I am writing a book on the Azad Hind Legion/Free Indian Legion of the Second World War. The Legion served with the German Army and was recruited with British Indian troops who were captured by the German Army in North Africa in 1942. I am particularly interested in those who were stationed in the Netherlands – Texel and Sandvoort. More specifically, I am interested in photographs of Sikh soldiers of the Legion. Thank you for your assistance.
