could react. To this end the armoured divisions were located further west and organisation was improved. There was no direct change in strategic thinking and when an improved concept was finished, within a continuous process of amendments, on 30 January, this Aufmarschanweisung N°3, Fall Gelb ("Deployment Directive, Case Yellow"), did not fundamentally differ from earlier versions. In this view only the fact that some of Von Manstein's friends managed to bring his proposals to Hitler's attention really caused a fundamental turn. The main consequence of the incident would have been that it disclosed, not the German plan, but the way the Allies would deploy in case of an invasion, allowing the Germans to adapt their attack accordingly. The adoption of the revised Fall Gelb by the Germans, while the Allies were still expecting Hitler to go ahead with the captured version meant that the Germans could set a trap. There would still be an attack made on central Belgium but this would merely be a diversion to pull as many troops as possible to the north while the main German attack fell on the Ardennes, and would then cross the Meuse between Sedan and the area north of Dinant, to penetrate as far as the Channel coast. In doing so the armies in Belgium would be cut off from their supplies and forced to surrender. This ruse may have been clever, but it would only work if Gamelin stuck to his original strategy; which was asking rather a lot, given that until 14 January 1940 his intuition had been impeccable. Had he not guessed correctly the content of the German's original Aufmarsschanweisung Fall Gelb''? However, Gamelin failed to change his strategy on the presumption the Germans would change theirs, despite misgivings from Gort and the British Government. Perhaps the Allies still believed that the captured documents were a 'plant'. Perhaps the British were embarrassed by the size of their contribution, and therefore hesitated to overly criticize their ally's strategy. Gamelin has been severely criticized for not changing his plan. His stance has been explained as an inability to believe that the very traditional German High Command would resort to innovative strategies, let alone to the even more novel "Blitzkrieg" tactics needed to make them work; any large concentration of forces being supplied through the poor road network in the Ardennes would have had to act very quickly. Also in this
