" 
 *"" the German troops moved the POWs westward into Germany in order to be clear of the Soviet advance from the east"" - ""in order to avoid the Soviet advance""? 
 *""Peter and George walked through an opening in the prisoner compound fence and ran towards Frankfurt in the hopes of reaching the American lines."" - to check, I read this as they left the compound, (literally) ran towards Frankfurt, and were then (presumably quite quickly) picked up? 
 *""After surviving the bombardments in Nuremberg, the POWs were resettled in a camp near Munich. "" - You could simplify to ""After surviving the bombardment, the POWs..."" - the Nuremberg context is established in the previous paragraphy. 
 *""However, they were given the opportunity to return to Nuremberg as wounded soldiers to obtain treatment.[20] The POWs agreed to return to Nuremberg because it was closer to the American lines."" > ""They were given the opportunity to return to Nuremberg, however, as wounded soldiers to obtain treatment; the POWs agree, because it was closer to the American lines."" It would avoid repetition and be a little shorter. 
 *""Juskalian was flown to Paris, France where he would present himself at the military post and request financial assistance."" - ""he presented himself"" (active, vice conditional) 
 *""An officer, who was already acquainted with George's older brother Richard (Dikran)"" - ""who knew George's older brother""? 
 *""When asked if he was related to Richard, George responded by saying Richard was his older brother and upon hearing this, he was given all the provisions he needed."" - I thought this seemed overly literal/long. How about ""George confirmed that Richard was his brother, and he was then given all the provisions he needed.""? 
 *""the staff and faculty of The Infantry School"" - I don't think the ""The"" needs a capital here, but happy to be corrected! 
 *""While at the School, he availed himself of the opportunity of taking airborne training and qualifying as a parachutist."" > ""While at the School, he took airborne training and qualified as a parachutist.""? (shorter)"
