Information obtained both during the progress of the Somme battle and since the suspension of active operations has fully established the effect of our offensive in keeping the enemy's main forces tied to the western front. A movement of German troops eastward, which had commenced in June as a result of the Russian successes, continued for a short time only after the opening of the allied attack. Thereafter the enemy forces that moved east consisted, with one exception, of divisions that had been exhausted in the Somme battle, and these troops were already replaced on the western front by fresh divisions. In November the strength of the enemy in the western theatre of war was greater than in July, notwithstanding the abandonment of his offensive at Verdun. [Sidenote: Somme offensive relieved Verdun.] It is possible that if Verdun had fallen large forces might still have been employed in an endeavor further to exploit that success. It is, however, far more probable, in view of developments in the eastern theatre, that a considerable transfer of troops in that direction would have followed. It is therefore justifiable to conclude that the Somme offensive not only relieved Verdun but held large forces which would otherwise have been employed against our allies in the east. The third great object of the allied operations on the Somme was the wearing down of the enemy's powers of resistance. Any statement of the extent to which this has been attained must depend in some degree on estimates. There is, nevertheless, sufficient evidence to place it beyond doubt that the enemy's losses in men and material have been very considerably higher than those of the Allies, while morally the balance of advantage on our side is still greater. [Sidenote: Enemy resistance feebler.] During the period under review a steady deterioration took place in the morale of large numbers of the enemy's troops. Many of them, it is true, fought with the greatest determination, even in the latest encounters, but the resistance of still larger numbers became latterly decidedly feebler than it had been in the earlier stages of the battle. Aided by the great depth of his defenses and by the frequent reliefs which his resources in men enabled him to effect, discipline and training held the machine together sufficiently to enable the enemy to rally and reorganize his troops after each fresh defeat. As our advance progressed, four-fifths of the total number of divisions engaged on the western front were thrown one after another into the Somme battle, some of them twice, and some three times; and toward the end of the operations, when the weather unfortunately broke, there can be no doubt that his power of resistance had been very seriously diminished.
