On Saturday morning, just about dawn, an airship appeared in the sky to the east of our line at this point, and dropped four red stars, which floated downward slowly for some distance before they died out. When our men, whose eyes had not unnaturally been fixed on this display of pyrotechnics, again turned to their front it was to find the German trenches rendered invisible by a wall of greenish-yellow vapor, similar to that observed on the Thursday afternoon, which was bearing down on them on the breeze. Through this the Germans started shooting. During Saturday they employed stupefying gas on several occasions in this quarter, but did not press on very quickly. One reason for this, given by a German prisoner, is that many of the enemy's infantry were so affected by the fumes that they could not advance. To continue the narrative from the night of Sunday, April 25. At 12:30 A.M., in face of repeated attacks, our infantry fell back from a part of the Grafenstafel Ridge, northwest of Zonnebeke, and the line then ran for some distance along the south bank of the little Haanebeek stream. The situation along the Yperlee Canal remained practically unchanged. When the morning of the 26th dawned the Germans, who had been seen massing in St. Julien, and to the east of the village on the previous evening, made several assaults, which grew more and more fierce as the hours passed, but reinforcements were sent up and the position was secured. Further east, however, our line was pierced near Broodseinde, and a small body of the enemy established themselves in a portion of our trenches. In the afternoon a strong, combined counter-attack was delivered by the French and British along the whole front from Steenstraate to the east of St. Julien, accompanied by a violent bombardment. This moment, so far as can be judged at present, marked the turning point of the battle, for, although it effected no great change in the situation, it caused a definite check to the enemy's offensive, relieved the pressure, and gained a certain amount of ground.
