Adenauer headed Cologne during World War I, working closely with the army to maximize the city's role as a rear base of supply and transportation for the Western Front. He paid special attention to the civilian food supply, enabling the residents to avoid the worst of the severe shortages that beset most German cities during 1918–19. In 1918, he invented a soy-based sausage called the "Cologne sausage" to help feed the city. In the face of the collapse of the old regime and the threat of revolution and widespread disorder in late 1918, Adenauer maintained control in Cologne using his good working relationship with the Social Democrats. In a speech on 1 February 1919 Adenauer called for the dissolution of Prussia, and for the Prussian Rhineland to become a new autonomous "Land" (state) in the "Reich". Adenauer claimed this was the only way to prevent France from annexing the Rhineland. Both the "Reich" and Prussian governments were completely against Adenauer's plans for breaking up Prussia. When the terms of the Treaty of Versailles were presented to Germany in June 1919, Adenauer again suggested to Berlin his plan for an autonomous Rhineland state and again his plans were rejected by the "Reich" government.
