Days to Remember by John Buchan — Read

The Salient of Ypres was to be a second time the scene of a heroic stand against hopeless odds. In April 1915 the front of the Salient was held by the French on the left, the Canadian Division and the British 28th Division in the centre, and the 27th Division on the right. On the 20th the Germans suddenly began the bombardment of the town with heavy shells. It was a warning to the British Command, for all their roads of supply for the lines of the Salient ran through Ypres, and such a bombardment must herald an attack on some part of their front.

The evening of Thursday, the 22nd, was calm and pleasant, with a light, steady wind blowing from the north-east. About 6.30 our artillery observers reported that a strange green vapour was moving over the French trenches. Then, as the April night closed in and the great shells still rained upon Ypres, there were strange and ghastly scenes on the left between the canal and the Pilkem road. Back through the dusk came a stream of French soldiers, blinded and coughing, and wild with terror. Some black horror had come upon them, and they had broken before a more than human fear. Behind them they had left hundreds of their comrades stricken or dead, with horrible blue faces and froth on their lips.
