One may also see now, very clearly, the paramount importance of the human factor in this arithmetic of war, the morale of men being of greater influence than generalship, though dependent on it, the spirit of peoples being as vital to success as the mechanical efficiency of the war-machine; and above all, one is now able to observe how each side blundered on in a blind, desperate way, sacrificing masses of human life without a clear vision of the consequences, until at last one side blundered more than another and was lost. It will be impossible to pretend in history that our High Command, or any other, foresaw the thread of plot as it was unraveled to the end, and so arranged its plan that events happened according to design. The events of March, 1918, were not foreseen nor prevented by French or British. The ability of our generals was not imaginative nor inventive, but limited to the piling up of men and munitions, always more men and more munitions, against positions of enormous strength and overcoming obstacles by sheer weight of flesh and blood and high explosives.
