The third offensive, Blücher-Yorck, was a diversionary thrust toward Paris to compel the French to move some of their reserves eastward away from the British. This would be accomplished by attacking the French Sixth Army along the Chemin des Dames ridge between Soissons and Reims. This attack, while succeeding in pushing the French Sixth Army south to Château-Thierry and the northern bank of the Marne River, failed to draw French reserves away from the British.
