As the numbers of POWs joining the legion swelled, the legion was moved to Königsbrück for further training. It was at Königsbrück that uniforms were first issued, in German "feldgrau" with the badge of the leaping tiger of "Azad Hind". The formation of the Indian National Army was announced by the German Propaganda Ministry in January 1942. It did not, however, take oath until 26 August 1942, as the "Legion Freies Indien" of the German Army. By May 1943, the numbers had swelled, aided by the enlistment as volunteers of Indian expatriates.
