" In the series of great offensive pressures which Joffre delivered during the whole of the spring and autumn of 1915, the French suffered nearly 1,300,000 casualties. They inflicted upon the Germans in the same period and the same operations 506,000 casualties. They gained no territory worth mentioning, and no strategic advantages of any kind. This was the worst year of the Joffre régime. Gross as were the mistakes of the Battle of the Frontiers, glaring as had been the errors of the First Shock, they were eclipsed by the insensate obstinacy and lack of comprehension which, without any large numerical superiority, without adequate artillery or munitions, without any novel mechanical method, without any pretence of surprise or manœuvre, without any reasonable hope of victory, continued to hurl the heroic but limited manhood of France at the strongest entrenchments, at uncut wire and innumerable machine guns served with cold skill. The responsibilities of this lamentable phase must be shared in a subordinate degree by Foch, who under Joffre’s orders, but as an ardent believer, conducted the prolonged Spring offensive in Artois, the most sterile and prodigal of all.
