 When the Control Commission was dissolved, the commissioners in their final report issued a blistering statement, stating that Germany had never sought to abide by Part V and the "Reichswehr" had been engaging in covert rearmament all through the 1920s.Under the Treaty of Versailles France was to occupy the Rhineland region of Germany until 1935, but in fact the last French troops left the Rhineland in June 1930 in exchange for Germany accepting the Young Plan.As long as the Rhineland was occupied by the French, the Rhineland served as a type of collateral under which the French would annex the Rhineland in the event of Germany breaching any of the articles of the treaty, such as rearming in violation of Part V; this threat was powerful enough to deter successive German governments all through the 1920s from attempting any overt violation of Part V. French plans as developed by Marshal Ferdinand Foch in 1919 were based on the assumption that in the event of a war with the "Reich", the French forces in the Rhineland were to embark upon an offensive to seize the Ruhr.
