A detailed picture of the German losses under our bombardment was given in the diary of an officer captured in a trench near Flers, and dated September 22d.
“The four days ending September 4th, spent in the trenches, were characterized by a continual enemy bombardment that did not abate for a single instant. The enemy had registered on our trenches with light, as well as medium and heavy, batteries, notwithstanding that he had no direct observation from his trenches, which lie on the other side of the summit. His registering was done by his excellent air service, which renders perfect reports of everything observed.
“During the first day, for instance, whenever the slightest movement was visible in our trenches during the presence, as is usually the case, of enemy aircraft flying as low as three and four hundred yards, a heavy bombardment of the particular section took place. The very heavy losses during the first day brought about the resolution to evacuate the trenches during the daytime. Only a small garrison was left, the remainder withdrawing to a part of the line on the left of the Martinpuich-Pozieres road.
“The signal for a bombardment by 'heavies' was given by the English airplanes. On the first day we tried to fire by platoons on the airplanes, but a second airplane retaliated by dropping bombs and firing his machine-gun at our troops. Our own airmen appeared only once for a short time behind our lines.
“While many airplanes are observing from early morning till late at night, our own hardly ever venture near. The opinion is that our trenches cannot protect troops during a barrage of the shortest duration, owing to lack of dugouts.
“The enemy understands how to prevent, with his terrible barrage, the bringing up of building material, and even how to hinder the work itself. The consequence is that our trenches are always ready for an assault on his part. Our artillery, which does occasionally put a heavy barrage on the enemy trenches at a great expense of ammunition, cannot cause similar destruction to him. He can bring his building material up, can repair his trenches as well as build new ones, can bring up rations and ammunition, and remove the wounded.
“The continual barrage on our lines of communication makes it very difficult for us to ration and relieve our troops, to supply water, ammunition, and building material, to evacuate wounded, and causes heavy losses. This and the lack of protection from artillery fire and the weather, the lack of hot meals, the continual necessity of lying still in the same place, the danger of being buried, the long time the wounded have to remain in the trenches, and chiefly the terrible effect of the machine—and heavy-artillery fire, controlled by an excellent air service, has a most demoralizing effect on the troops.
“Only with the greatest difficulty could the men be persuaded to stay in the trenches under those conditions.”
There were some who could not be persuaded to stay if they could see any chance of deserting or malingering. For the first time on our front the German officers could not trust the courage of their men, nor their loyalty, nor their sense of discipline. All this horror of men blown to bits over living men, of trenches heaped with dead and dying, was stronger than courage, stronger than loyalty, stronger than discipline. A moral rot was threatening to bring the German troops on the Somme front to disaster.
Large numbers of men reported sick and tried by every kind of trick to be sent back to base hospitals.
