The British soldiers who had been engaged in the fighting about Neuve Chapelle spent all of March 13, 1915, in digging trenches in the wet meadows that border the Des Layes. On the following day the two corps that had fought so valiantly were sent back to the reserve.
The German commanders, in the meantime, had been preparing for a vigorous counterattack. They planned to make their greatest effort fifteen miles north of Neuve Chapelle, at the village of St. Eloi, and trained a large section of their artillery against a part of the British front, which was held by the Twenty-seventh Division. The preparation of the Germans was well concealed on March 14 by the heavy mist that covered the low country. The bombardment started at 5 p. m., the beginning of which was immediately followed by the explosion of two mines which were under a hillock that was a part of the British front at the southeast of St. Eloi. The artillery attack was followed by such an avalanche of German infantry that the British were driven from their trenches. This German success was followed up by the enfilading of the British lines to the right and left, with the result that that entire section of the British front was forced back.
That night a counterattack was prepared. It was made at 2 a. m., on March 15, by the Eighty-second Brigade, which had the Eightieth Brigade as its support. The Eighty-second Brigade drove the Germans from the village and the trenches on the east. The Eightieth Brigade finished the task of regaining all of the ground that had been lost except the crater caused by the explosion of the mines. Among the regiments that made a most enviable record for themselves in this action were Princess Patricia's Canadian Light Infantry, the Fourth Rifle Brigade, the First Leinsters, the Second Cornwalls, and the Second Royal Irish Fusiliers. The "Princess Pat's," as the Canadian troops were known in the home land, were the first colonial soldiers to take part in a battle of such magnitude in this war. Their valor and their ability as fighting men were causes of great pride to the British.
Before leaving the Neuve Chapelle engagement and what immediately followed it, it is well to give a brief survey of the actions along the line that supported it. To prevent the Germans from taking troops from various points and massing them against the main British attack, the British soldiers all along that part of the front found plenty of work to do in their immediate vicinity. Thus, on March 10, 1915, the First Corps attacked the Germans from Givenchy, but there had been but little artillery fire on the part of the British there, and the wire entanglements stopped them from more than keeping the German troops in the position which they had held. The Second Corps, on March 12, was to have advanced at 10 a. m. southwest of Wytschaete. The fog that prevailed on that day, however, prevented a movement until 4 p. m. Then the First Wiltshires and the Third Worcesters of the Seventh Brigade began a movement which had to be abandoned when the weather thickened and night fell.
The attack on L'Epinette, a hamlet southeast of Armentières, was much more successful on the same day. The Seventeenth Brigade of the Fourth Division of the Third Corps advanced at noon, with the Eighteenth Brigade as its support. It advanced 300 yards on a front a half mile in length, carrying the village, which it retained in spite of all the counterattacks.
The work of the artillery was not confined to the main attack, for it was very effective in shelling the Quesnoy railway station east of Armentières, where German reenforcements were boarding a train for the front. The British artillery fire was effective as far as Aubers, where it demolished a tall church spire.
The work of the aviators, from March 10 to 12 inclusive, deserves special mention. Owing to the adverse weather conditions, it was necessary for them to fly as low as from 100 to 150 feet above the object of their attack in order to be sure of their aim. Nevertheless they destroyed one of the piers of the bridge over the Lys at Menin. This bridge carried the railroad over the river. They also wrecked the railway stations at Douai, Don, and Courtrai. The daring of the British aviators even took them over Lille, where they dropped bombs on one of the German headquarters.
To summarize the fighting about Neuve Chapelle, it may be said that the British had advanced something more than a mile on a three-mile front, replacing the sag which had existed in their line by a sag in that of the Germans. The British had not won the ridges which were the key to Lille, but they had advanced their trenches close to those ridges. The entire moral effect was a gain for the British; but even that and the gain in advancing the front had been obtained at a too great sacrifice of the life of their men. The words of the Germans in characterizing the tremendous bombardment of the British were: "That is not war; it is murder."
The belief in the supposed superiority of the German artillery was so shaken in the minds of the General Staff as a result of the fighting on the Neuve Chapelle front that they shortly after issued an order to try a series of experiments on animals with asphyxiating gases.
