With the morning relief of the 3rd, 60 sappers were sent to the trenches, who in addition to the duty of overseers laid platforms in No. 14 and the 21-gun batteries. Sergeant Philip Morant, while superintending on the right, was slightly wounded in the shoulder by a rifle bullet, which, being almost spent, bounded back after delivering the blow. This was his first day in the trenches. No. 1 battery on the left attack, which was much cut up, was completely renovated by thirteen sappers; and four miners performed good service in blasting a communication to the ammunition caves. In the ensuing night the advance boyau to rifle-pit on the right attack was prolonged and strengthened, and a strong party of the corps worked with acknowledged energy in constructing No. 12 mortar battery on the left. Some also were with a line party adding solidity to the broad parapet of No. 8 battery, who, however, were subsequently removed, as the clear moon, shining in a cerulean sky, exposed the men to an annoying fire of grape from the Redan. Two nights later, there were forty-three of the corps in the trenches; twenty being scattered in the right works, and twenty-three in the left. A sortie on the left sap of the Gordon attack interrupted the operations, but the enemy was driven back without effecting any serious detriment to the works. A heavy fire of shells was also directed against the 21-gun battery, and though the casualties for the night amounted to 4 killed, 18 wounded, and 2 missing, none of the sappers were touched. At the time of the attack eight rank and file of the corps were in No. 14 battery repairing embrasures, 1 in the second parallel making loop-holes and patching up the parapet, 2 in No. 8 battery replacing dislodged sand-bags, and 2 in the 21-gun battery filling up the chasms in the fourteenth embrasure and altering the features of the twentieth.
