The first serious operation of the spring of 1916 upon the British line was a determined German attack upon that section which lies between the Ypres-Comines Canal and the Ypres-Comines railway on the extreme south of the Ypres salient; Hill 60 lies to the north of it. In the line of trenches there was one small artificial elevation, not more than thirty feet above the plain. This was called the Bluff, and was the centre of the attack. It was of very great importance as a point of artillery observation. During the whole of February 13 the bombardment was very severe, and losses were heavy along a front of several miles, the right of which was held by the Seventeenth Division, the centre by the Fiftieth, and the left by the Twenty-fourth. Finally, after many of the trenches had been reduced to dirt heaps five mines were simultaneously sprung under the British front line, each of them of great power. The explosions were instantly followed by a rush of the German infantry. In the neighbourhood of the Bluff, the garrison, consisting at that point of the 10th Lancashire Fusiliers, were nearly all buried or killed. To the north lay the 10th Sherwood Foresters and north of them the 8th South Staffords, whose Colonel, though four times wounded, continued {8} to direct the defence. It was impossible, however, to hold the whole line, as the Germans had seized the Bluff and were able to enfilade all the trenches of the Sherwoods, who lost twelve officers and several hundred men before they would admit that their position was untenable. The South Staffords being farther off were able to hold on, but the whole front from their right to the canal south of the Bluff was in the hands of the Germans, who had very rapidly and skilfully consolidated it. A strong counter-attack by the 7th Lincolns and 7th Borders, in which the survivors of the Lancashire Fusiliers took part, had some success, but was unable to permanently regain the lost sector, six hundred yards of which remained with the enemy. A lieutenant, with 40 bombers of the Lincolns, 38 of whom fell, did heroic work.
