On February 12, 1916, the Germans launched fresh attacks in the west, near Steenstraat and Het Sas, and attempted to cross the Yser. After being smartly checked, they furiously attacked the British trenches between the Ypres-Comines Canal and the railway, and succeeded in capturing one of them for a length of 600 yards. This trench, on account of its frequently changing hands, came to be known as the "International Trench." A few days later (March 2) the British retook it.

The struggle now became limited to a continuous artillery duel, with occasional surprise infantry attacks. The hamlet of St. Eloi to the south was the scene of constant fighting for the possession of the shell-craters.

On April 19, the fighting assumed a more serious character. An unimportant German attack near St. Eloi and along the Ypres-Langemarck Road was the prelude to operations by considerable enemy forces, having for their objective the great undulating slopes between Hill 60 and Armentières.

BRITISH DEFENCE WORKS IN FRONT OF YPRES

The first of these attacks took place on April 25, 1916, but failed. Two days later a night attack with gas was repulsed with hand grenades.

A third attempt was made in May, 1916, more to the south towards Armentières, on the sides of the road connecting that town with Ypres. The British, entrenched in a wood near Ploegsteert Village, were assailed by three German columns, and were only able to repulse two of them. The third took the position, but Scottish troops counter-attacked and drove the Germans back.

The most important of the enemy attacks during this period took place on June 1. The preparations included a concentration of troops between Tournai and Baisieux, from May 21 to 27, supported by guns of all calibres. The attack was carried out in considerable strength between Hooge and the Ypres-Comines Railway.

The artillery preparation began at 9.15 a.m. on June 1, and at noon the first assaulting wave entered the front-line trenches. The battle died down for a few minutes in the evening, only to break out again during the night. The Germans succeeded in crushing in the front to a depth of some 700 yards in the direction of Zillebeke, but the next day a portion of the lost ground was retaken by the Canadians.
