The French met with better success on the British left. Under the command of General Putz they made an attack on Het Sase and Steenstraate. The sharpshooters of the Zouaves and Algerians took a trench in front of the latter place and entered the village. They fought on to the canal by the end of that day, which was May 15, 1915. More than six hundred Teuton dead were counted after that engagement. At the same time the Zouaves captured Het Sase with great ease, because the artillery had rendered its defenders useless for more fighting. The Germans, however, were not inclined to give up the town so easily. They bombarded Het Sase that night, using asphyxiating shells. Nothing daunted, the Zouaves put on their respirators and drove off with hand grenades and rifle fire the Germans who followed in the wake of the poisonous shells. On the following day it was said that the only Germans left alive on the left side of the Yperlee Canal were either wounded or prisoners. The French had destroyed three German regiments, taken three redoubts, and captured four fortified lines and three villages. In this connection it may not be amiss to note that the French reported that, on May 15, 1915, the German Marine Fusiliers who were attempting to hold the Yperlee Canal concluded it was the better part of valor to surrender. Before the Germans could relinquish their places they were shot down by their comrades in the rear. Fighting along the line of the salient continued with more or less vigor for nearly ten days, but, until May 24, 1915, there were no engagements that had much out of the ordinary. On that date, however, the entire front from Bellewaarde Lake to Shelltrap, a line three miles in length, was bombarded with asphyxiating shells. This was followed by a gas cloud that was sent against the same extent of trenches. The wind sent the cloud in a southwesterly direction, so that the deadly fumes got in their work along nearly five miles of the front. It is asserted that the cloud was 40 feet in height, and that the Germans continued to renew the supply of gas for four and a half hours. It had little effect wherever the British used their respirators, for they managed to stay in their positions without undue inconvenience. Those who suffered the most from the gas cloud were the infantry of the Fourth Division on the left. The cloud which had followed the asphyxiating shells was in turn followed by a severe bombardment from three sides--the east, northeast, and north. The principal attacks were made in the neighborhood of Shelltrap, the British front along the Roulers railroad, and along the Menin road in the vicinity of Bellewaarde Lake. In those places the British were pushed back at least temporarily; but counterattacks were delivered before nightfall, and the greater part of the lost ground regained. Thus, to the disappointment of the Germans, their extra effort, with all the means of warfare
