Like many Allied leaders, Wilson believed after the victory at the Marne that the war was as good as won. He told Joffre's staff officer General Henri Mathias Berthelot (13 September) that the Allies would be in Elsenborn on the German-Belgian frontier in four weeks (Berthelot thought three). Wilson also helped to persuade Joffre (late September) to allow the BEF to redeploy further to the left of the Allied line. When French, Murray and Wilson arrived to confer with Foch (then commanding the French Armies in that sector) in early October 1914, Foch greeted Sir John with a handshake but threw his arms around Wilson's neck and kissed him on both cheeks.
