Foch was surprised by the German offensive (""Bluecher"") on the Chemin des Dames (27 May). Foch believed it was a diversion to draw Allied reserves away from Flanders. This was partly true, although the planned German Flanders Offensive ("Hagen") never took place. The Allied armies under Foch's command ultimately held the advance of the German forces. The celebrated phrase, "I will fight in front of Paris, I will fight in Paris, I will fight behind Paris", attributed both to Foch and Clemenceau, illustrated the Généralissime's resolve to keep the Allied armies intact, even at the risk of losing the capital. The British General Sir Henry Rawlinson, commanding the British Fourth Army, commented after meeting Foch: "I am overjoyed at his methods and far-sighted strategy. I was in close touch with him in 1916. He is a better man now than he was then, for his fiery enthusiasm has been tempered by adversity." Rawlinson also noted Foch's intense Frenchness: "He knew nothing of Britain. The Rhine was for him a river of life and death."
