The GQG headquarters moved further eastwards to Provins in Seine-et-Marne on 26 March 1918. After the armistice GQG moved to Metz in the newly reacquired Moselle department on 1 December 1918 and returned to Chantilly on 29 January 1919. GQG was dissolved on 20 October 1919 in accordance with a request from the War Ministry on 14 October which also abolished the zone of army control. The powers previously delegated to GQG were returned to the chief-of-staff of the army. During the Second World War the German army took control of the GQG First World War archives and sent many of the most secret documents to Berlin for analysis. These documents were recovered by the USSR at the end of the war and taken back to Moscow for processing. They were not returned to France until after the dissolution of the Soviet Union in the 1990s.
