So intense had been the preliminary fire that every wire connecting with the rear had been severed, and it was only the actual explosion upon the mound--an explosion which buried many of the defenders, including two machine-guns with their detachments--which made the situation clear to the artillery in support. The 19th and 20th Brigades concentrated their thirty-six 18-pounders upon the mound and its vicinity. The German infantry were already in possession, having overwhelmed the few survivors of the 2nd Cornwalls and driven back a company of the 2nd Irish Fusiliers, who were either behind the mound or in the adjacent trenches to the east of the village. The stormers had rushed forward, preceded by a swarm of men carrying bombs and without rifles. Behind them came a detachment of sappers with planks, fascines, and sand-bags, together with machine-gun detachments, who dug themselves instantly into the shattered mound. The whole German organisation and execution of the attack were admirable. Lieutenants Fry and Aston of the Cornwall Light Infantry put up a brave fight with their handful of shaken men. As the survivors of the British front line fell back, two companies of the 1st Cambridge Territorials took up {31} a rallying position. The situation was exceedingly obscure from the rear, for, as already stated, all wires had been cut, but daring personal reconnaissance by individual officers, notably Captain Follett and Lieutenant Elton, cleared it up to some extent. By nine o'clock preparations had been made for a counter-attack, the 1st Leinsters and 1st Royal Irish, of the 82nd Brigade, being brought up, while Fortescue's 80th Brigade was warned to support the movement.
