The lull was broken, however, by a sharp fight upon July 6, in which Prowse's 11th Brigade of the Fourth Division took, and permanently held, a section of the German line. This considerable action was fought at the extreme northern end of the British line, where it joined on to the French Moroccan troops to the north of Ypres. The sudden and swift advance of the 1st Rifle Brigade, the leading British battalion, seems to have taken the Germans by surprise, and, dashing forwards, they seized two lines of trenches and established themselves firmly within them. The 1st Somerset Light Infantry shared the credit and the losses of the charge. They were in immediate support of the Rifle Brigade, their task being to dig a communication trench. A hundred prisoners and a number of mortars and machine-guns were the immediate trophies. Three times during the day did the Germans counter-attack in force, and three times they were driven back with heavy loss. Their total casualties certainly ran into a thousand. On the other hand, both the Rifle Brigade and the Somersets suffered severely, partly from flanking machine-gun fire in the attack, but chiefly, as usual, from heavy shell-fire afterwards. Indeed, it may be said that a victorious battalion was too often an exhausted battalion, for since the German guns had the precise length of the captured trench, the more heroically it was held the heavier the losses. Until the artillery of the Allies should be able to dominate that of the enemy, it was difficult to see how ground could be gained without this grievous after-price to be paid. On this occasion it was {155} paid to the full, but the ground was permanently occupied, and a heavy blow was struck at the Bavarians and Prussians who held that portion of the line. Part of the 12th Brigade (Anley) took over some of the captured trenches from the 11th, and came in for some of the German anger in consequence. The 2nd Lancashire Fusiliers were very heavily shelled, losing their commanding officer, Colonel Griffin, the machine-gun officer, and the adjutant on the morning of July 7. A sap ran up to the trench, and this was the scene of desperate bomb-fighting, the Fusiliers expending eight thousand bombs in two days. So great was the pressure that part of the 1st Warwicks came up in support. There were several infantry advances of the enemy, which were all crushed by the British fire. No dervishes could have shown more devoted courage than some of the Germans. In one rush of sixty men all were shot down, which did not prevent another forty from emerging later from the same trench. Gradually they learned that their task was impossible, and the position remained with the British. Altogether the Lancashire Fusiliers lost 8 officers and 400 men in this action.
