When the Allied Forces moved in to take possession of the field in late April, they found that Prisoners of War and townspeople had looted until they left a deserted installation. Fürstenfeldbruck was occupied by American forces and was at first was the home of an Army engineering battalion. After some reconstruction, Fürstenfeldbruck became the Headquarters, UAAF/ET Replacement Depot (Provisional) in November 1945. Tens of thousands of fresh Army Air Force replacement troops from the Zone of the Interior (ZI), as the USA was referred to, arrived in trains from Le Havre and were housed in stone barracks for a week or so before being assigned to their final airbase or other destination, where they replaced veteran airmen who were redeployed home for discharge, also through the Replacement Depot. The offices and base personnel housing were excellent and included a fully equipped theater, natatorium (indoor swimming pool), mess hall, and 4-man bedrooms, each with its own bathroom, all housed in stone buildings rather than wooden barracks or tents.
