Four days after was commenced No. 8 battery of the same attack for eight guns. The strength of the sappers employed at it varied each relief, but at one time there were 40 of the corps engaged in its construction. It was traced by Major Bent and Lieutenant Graham on a shoulder of the right of the third parallel. Lance-corporal George H. Collins, a very apt sapper, was very ready in measuring the distances, and afterwards in distributing and superintending the working party. When finished, the battery was an excellent field structure, and seemed furbished up like a model for the inspection of the curious. Its slopes, levels, and angles were true, its magazines well built and strong, and the genouillères were revetted in a way to admit the guns being run well up the embrasures, the cheeks of which were protected by hide bags. This, as well as No. 7 battery, were completed by the mutual co-operation of the line and sappers, the latter taking those portions which demanded art and dexterity. The rolling of heavy ordnance into these batteries on ponderous carriages, down narrow trenches deep in mud and mended with fascines and stones, was a very difficult operation. Now and then the ropes broke, and the strong iron hooks which connected them to the wheels of the carriage, yielding their tension to the strain, became straightened like bars, and jerked from the eyes in which they were locked. To make sure of the cut through which to pass the gun and its carriage in the dark was a masterpiece of dexterity; and in one instance a 68-pounder was pulled so wide of the mark that the sappers were obliged to enlarge the gap in the parapet. This was a far easier expedient than backing the gun to make another run for the opening. It took about eighty artillerymen, and no end of assistants, to man the drag-ropes and pass the great siege gun in question to its platform in No. 7 battery. Meanwhile the brigades on the right attack were no less zealously occupied in furthering the general works. Among a wearying number of incidental services, they made magazines, platforms, and sand-bag traverses. They also formed rifle-pits on a knoll 130 yards in advance of the right mortar-battery, where, the ground being rocky, protection for the light troops was procured by stones and sand-bags built on the crest of the pit. On the night of the tenth the sappers toiled for ten hours unrelieved, and quitted the works with the commendation of their officers for having worked “remarkably well.”
