 Under the pressure of horrendously destructive German attacks beginning on March 21, 1918, the Entente eventually settled under Field Marshal Ferdinand Foch.The Germans generally led the Central Powers, though German authority diminished and lines of command became confused at the end of the war.World War I strategy was dominated by the "Spirit of the Offensive", where generals resorted almost to mysticism in terms of a soldier's personal "attitude" in order to break the stalemate; this led to nothing but bloody slaughter as troops in close ranks charged machine guns.
