My grandfather was in British Indian Army, ASC(MT). Was taken to Germany as POW. He joined Azad Hind Fauz in Germany unit no. 950.
Can any one have some information on the training and movement of this unit and related history or where can I get it?
Here’s a brief outline and some references for further investigation: http://www.axishistory.com/index.php?id=2157
You’d need more information about your grandfather for more detail as he could have served in many places.
