Before closing this chapter, dealing with the gas {78} attacks to the north of Ypres, and beginning the next one, which details the furious German assault upon the contracted lines of the Fifth Army Corps, it would be well to interpolate some account of the new development at Hill 60. This position was a typical one for the German use of gas, just as the Dardanelles lines would have been for the Allies, had they condescended to such an atrocity upon a foe who did not themselves use such a weapon. Where there is room for flexibility of manoeuvre, and a temporary loss of ground is immaterial, the gas is at a discount; but where there is a fixed and limited position it is without respirators practically impossible to hold it against such an agency. Up to now the fighting at Hill 60 had furnished on both sides a fine epic of manliness, in which man breasted man in honest virile combat. Alas, that such a brave story should have so cowardly an ending! Upon the evening of May 1 the poisoners got to work, and the familiar greenish gas came stealing out from the German trenches, eddied and swirled round the base of the hill, and finally submerged the summit, where the brave men of the Dorsets in the trenches were strangled by the chlorine as they lay motionless and silent, examples of a discipline as stern as that of the Roman sentry at Herculaneum. So dense were the fumes that the Germans could not take possession, and it was a reinforcement of Devons and Bedfords of the 15th Brigade who were the first to reach the trenches, where they found the bodies of their murdered comrades, either fixed already in death or writhing in the agonies of choking. It is said that the instructions of the relieving force were to carry up munitions and to carry down the Dorsets. One officer and {79} 50 men had been killed at once, while 4 officers and 150 men were badly injured, many of them being permanently incapacitated. The 59th Company of Royal Engineers were also overwhelmed by the fumes, three officers and many men being poisoned. The gas attack upon Hill 60 on May 1 may have been a mere experiment upon the part of the Germans to see how far they could submerge it, for it was not followed up by an infantry advance. A more sustained and more successful attack was made by the same foul means upon May 5. Early in the morning the familiar cloud appeared once more, and within a few minutes the British position was covered by it. Not only the hill itself, but a long trench to the north of it was rendered untenable, and so was another trench two thousand yards north of Westhoek.
