The British Seventh Division at Festubert continued to work south along the German trenches. Its bayonets and bombs cleared the way before it. The plan was for them to continue toward Rue d'Ouvert, Chapelle St. Roch, and Canteleux. In the meantime the Second Division, on the left of the Seventh Division, was to fight its way to Rue du Marais and Violaines. The Indian contingent had received orders to keep in touch with the Third Division. The Fifty-first Division was sent to Estaires to act as a support to the First Army. By the night of May 17, 1915, the British held all of the first line of German trenches from the south of Festubert to Richebourg l'Avoue. For a part of that distance the second and third lines of trenches had been taken and held; and still farther forward the British possessed many important points. Moreover the British soldiers were so inspired with their success that they desired to press on in spite of the fact that the nature of the country was such that they were wet through and covered with mud. It was not all enthusiasm, however. Mingled with the desire for victory was a desire for revenge. The British on this part of the line were enraged by the use of gas at Ypres and the sinking of the _Lusitania_. On the night of May 17, 1915, the Fourth Cameron Highlanders, a Territorial battalion, met with disaster. The men composing this unit were from Inverness-shire, Skye, and the Outer Islands. Many of them had been gamekeepers and hence were accustomed to outdoor life and the handling of guns, all of which aided them in saving the remnant of their command. They had been ordered to take some cottages, occupied by German soldiers as a makeshift fortification. The Cameronians on the way to the attack fell into a ditch which was both deep and wide. It was necessary for them to swim to get across the ditch in some places. In the meantime Highlanders were being slain by German shells and the rifle fire that the men in the cottages rained upon the Scots. One company was annihilated. Another company lost its way. The rear end of a German communicating trench was reached by a third company. Long before midnight this company was almost without ammunition. Two platoons reenforced it at midnight; but the reenforcements had no machine guns, which would have given at least temporary relief. Under the circumstances the only thing for the Territorials to do was to retreat. The Germans made that quite as perilous a venture as the advance had been. Only half of those who started for the cottages returned. Among the slain was the commander, and twelve other officers were also killed.
