Realistically, accepting a strategy of attrition was the only option. To simply sit on the defensive behind your works was to play for a draw.
Not true. The French sat behind their trenches not only because the Germans had broken their spirit, but because the Americans were coming. The US Army's numbers won the war, but the French saved countless lives by not attacking. Likewise, after the debacle of Passchendale, Haig rested his men for months before the German spring offensives, waiting for the Americans to enter the fray.
As for casualties being similar, I don't believe it. If they were, Germany would not have been able to carry on the war, considering she was also fighting in Russia [and Italy to some extent]. The figures must be inflated, and I read a book called, "The Myth of the Great War" by John Mosier, which argues for these inflations, saying that the German casualty figures given are often for months of combat rather than actions, so that the German deaths are for all fronts, and all battles. For instance, it is common to say that there were 600,000 German casualties at the Somme. But in reality, it is 600,000 German casualties on all fronts during the Somme combat. To feel better about themselves, British historians have given the Germans ludicrously high casualty figures, so that they are comparable to British/French ones for given actions.
Otherwise, how could Germany fight for 4 years????
Moreover, arguing that Haig was a believer in the attrition strategy is missing the facts. Haig, and many others believed that Germany was always on the edge of disaster, and that one solid push would force the mythical "breakthrough". He kept hammering away in the misguided belief that he could break the German lines and force a victory, not by attrition, but by tactical success.
