London Protocol
After the US Army had invaded the Province of Saxony in April 1945 the "U.S. Group Control Council, Germany" (precursor of the OMGUS) reappointed him land-captain of the Province of Saxony. By early July the US Army retired in order to allow the Red Army taking Prussian Saxony as part of its Soviet occupation zone, as agreed by the London Protocol in 1944.
