The Germans started a heavy bombardment of the cavalry on May 13, 1915, when the rain was pouring in torrents and a north wind was adding to the discomforts of the British. The fiercest part of this attack was on the Third Division. Some idea of the fierceness of the bombardment can be gained when it is known that in a comparatively short space of time more than eight hundred shells were hurled on a part of the British line which was not more than a mile in length. In places the British were buried alive. In spite of the destructive fire, the North Somerset Yeomanry, commanded by Lieutenant Colonel Glyn, charged the Germans who were advancing on their trenches under cover of the bombardment. The charge was effective, and the Teutons were driven headlong toward their own trenches. But the German artillery had the range of the Seventh Brigade on the right, and poured upon it such a fire that it retreated several hundred yards, leaving the right of the Sixth Brigade exposed. As soon as possible the British made an attempt to remedy the defect in their line, and found it necessary to make a counterattack. In this counterattack very satisfactory results were obtained by the use of the Duke of Westminster's armored motor cars. The British regained the lost ground, but they found it impossible to retain it, for the Teuton's heavy artillery had the range of the position so accurately that no man could live there. The result of the day's fighting was a farther pushing back of the line of the British so that it bent backward from Verlorenhoek and Bellewaarde Lake. In addition to being forced back, the British suffered a large loss of men, especially officers. The infantry on the left had been fiercely attacked on this same day; but it managed to keep from being driven from its position. One of the defenders of this part of the line was a territorial battalion, the London Rifle Brigade. There were only 278 men in the battalion at the beginning of the day, it having suffered severe losses previously. By night ninety-one more had been lost. Four survivors, under command of Sergeant Douglas Belcher, and two hussars whom the sergeant had added to his squad, held that part of the line in the face of repeated attacks. These plucky men not only made the Germans think the front was strongly defended there by using quick-firing methods, but they undoubtedly saved the right of the Fourth Division. Another especially gallant piece of work on the part of the British was done by the Second Essex, the reserve battalion of the Twelfth Brigade. With a bayonet charge they drove the Germans from Shelltrap Farm, which was between the Langemarck and Poelcappelle highways, and, though it was held by first one side and then the other, the British had it at the close of the day in spite of the bombardment it received.
