From February onward, attacks and counter-attacks took place almost daily and only came to an end early in April, after the French had captured the crest. On February 17, the explosion of a mine enabled the French to enter the west sector of the enemy’s first line. Attacks and counter-attacks continued for five days, during which Colonel Bacquet was mortally wounded while leading his troops. The French held the whole of the western bastion, and began to make progress towards the eastern bastion. From March 13 to 21 they renewed their attacks and captured the enemy’s first line. [Illustration: EPARGES IN 1915. SENTRY IN TRENCH] On March 27, a battalion of Chasseurs made a fresh advance, and on April 5 began the last great attack which was to continue day and night until the 9th. Two regiments attacked in the rain, but the muddy ground greatly impeded their movements, and it seemed at times as if the attack would fail. In the evening the French occupied some of the trenches, but the use of aerial torpedoes, which pulverized whole rows of men, and a massed counter-attack launched at 4.30 on the morning of the 6th, forced them to give up part of the ground gained in the first advance. On the evening of the 6th, and throughout that night, in spite of the incessant rain, the trenches were retaken and the enemy driven back foot by foot, with a loss of 100 prisoners, including several officers. The French replied to the German counter-attacks with bayonet charges or barrage fire. The communicating trenches were bombarded, levelled, or blocked up. On the 8th, two regiments of infantry and a battalion of Chasseurs made a fresh bayonet charge. At 10 o’clock the summit and the western crest were strongly held, and by midnight, after fifteen hours of strenuous, uninterrupted fighting, almost the whole of the crest was in the hands of the French. During the night of the 8th, the relief of the troops was carried out, but the ground was so muddy that men sank into it, stumbling and slipping at every step. Fourteen hours passed in blinding rainstorms before the fresh troops were established in position. At 3 o’clock in the afternoon of the 9th the attack was resumed. The ground was full of deep holes in which men sometimes disappeared. At the moment when the eastern edge of the plateau was reached a cloud of fog descended over the crest. Firing was out of the question. The Germans counter-attacked and forced the French to retreat momentarily, but half an hour later the French retook the lost ground in a furious charge, and by 10 o’clock at night held the whole of the Eparges Heights. Only Combres Hill, threatened by the machine-guns of Eparges and St. Remy, remained in the hands of the Germans.
