I found LT Alfred D Sensenbach`s account of being captured near St, Vith, Belgium 21 Sept `44 & his journey to Stalag VI G in Bonn and staying for 5 months before being sent to another camp.
It`s from the book "Front Line Surgeons: A History of the Third Auxiliary Surgical Group", by Clifford L Graves.
its in a large .pdf file, almost 200MG.
Lt Sensenbach`s story starts on page 212 & there are 8 pages in the account.

I`ll just post the 2 pages describing the location of Stalag VI G and the bombing of the hospital, evacuated to Siegborg, then to Limburg. He says the hospital he was at was in Bonn on the west side of the Rhine.
1st Lt. Alfred D. Sensenbach MAC
Sergeant Loren R. Mullison
T/4 Luis C. Hultine
These three men disappeared on a journey for the delivery of pay. They were last seen at 0900 21 September near Bastogne, Belgium. No trace has been found of them or their car. [Editor’s Note: The three were captured by the Germans and were POWs for the remainder of the war.]
