The gain of ground by the Germans from north to south in this engagement necessitated a drawing-in of the line from east to west over a front of nearly eight miles in order to avoid a dangerous projecting salient at Zonnebeke. It was hard in cold blood to give up ground which had been successfully held for so many months, and which was soaked with the blood of our bravest and best. On the other hand, if it were not done now, while the Germans were still stunned by the heavy losses which they had sustained and wearied out by their exertions, it might be exposed to an attack by fresh troops, and lead to an indefensible strategic position. [Sidenote: May 2.] Upon Sunday, May 2, they made a fresh attack on the north of Ypres along the front held by the French to the immediate south of Pilken and along the British left to the east of St. Julien, where the newly-arrived 12th Brigade (Anley) and the remains of the 10th and 11th were stationed. The 12th Brigade, which came up on May 1, consisted at that time of the 1st King's Own Lancasters, 2nd Lancashire Fusiliers, 2nd Essex, 5th South Lancashires (T.F.), 2nd Monmouths (T.F.), and 2nd Royal Irish. The attack was in the first instance carried out by means of a huge cloud of gas, which was ejected under high pressure from the compressed cylinders in their trenches, and rapidly traversed the narrow space between the lines. As the troops fell back to avoid asphyxiation they were thickly sprayed by shrapnel from the German guns. The German infantry {76} followed on the fringe of their poison cloud, but they brought themselves into the zone of the British guns, and suffered considerable losses. Many of the troops in the trenches drew to one side to avoid the gas, or even, in some cases, notably that of the 7th Argyll and Sutherland Highlanders, waited for the gas to come, and then charged swiftly through it to reach the stormers upon the other side, falling upon them with all the concentrated fury that such murderous tactics could excite. The result was that neither on the French nor on the British front did the enemy gain any ground. Two battalions of the 12th Brigade--the 2nd Lancashire Fusiliers and the 2nd Essex--suffered heavily, many of the men being poisoned. The Lancashire Fusiliers lost 300 men from this cause, among them the heroic machine-gunner, Private Lynn, who stood without a respirator in the thick of the fumes, and beat off a German attack almost single-handed, at the cost of a death of torture to himself.
