Hello, I am trying to find out what the exact work of Graves Registration Units (GRU) was. Aftre the Rhine crossin by XII and XXX Corps two GRU were active in the area just east of the Rhine: 33 GRU and 35 GRU. Those two appear on some of the crosses that were placed on graves. Here's an example of a list made by the German local authorities in the summer of 1945 (see bottom). Nor all graves if British servicemen are marked with the unit number of the GRU, in fact, most are not. My question: What's the procedure? The combat units buried their war dead on the battlefield - correct? They also placed crosses with names on the graves - correct? Then the GRU appears - 35 GRU only starts its work on the battlefield on April 1st, 1945 - that's a week after the Rhine crossing. Here's the page from the war diary: All it says about their work is: "registrations continue" So, this means they go around the battlefield and register the graves that had previously been created by the units who had buried their dead? No further identification of unidentified was undertaken by GRUs - correct? Who reported back to "above" that a man had been killed - his original unit? Or the GRUs? And how long after his death would this have happened? GRUs consisted of 4 officers/NCOs and 17 OR: I am trying to find out the systematics behind this whole process and would appreciate any further information. Thank you!
