During the next fortnight the volume of the enemy’s fire increased daily; fresh batteries were unmasked in various directions, and everything tended to confirm the reports of spies and deserters that the French, now about 40,000 strong, were preparing for an attack in force. The preliminary bombardment began at 2 A.M. on the 16th of December, when Napoleon concentrated the fire of five batteries upon Fort Mulgrave, one of the most important of the western series of redoubts. It was held by a mixed force: a body of Spaniards occupied the northern half of the work; the southern was in charge of a detachment of British, under Captain W. Conolly, Royal Irish Regiment. By the end of the day the redoubt was in ruins, with half its garrison of seven hundred men disabled; at two o’clock in the morning of the 17th the French advanced against it, but though in overpowering force, for half an hour they made no progress till the Spaniards were seized with panic and left the British in the lurch. The enemy had begun to occupy the northern end of the work, when Conolly, though himself hard pressed, sent a subaltern and thirty-six men to retake it. With splendid courage this handful of soldiers drove back the Republicans, and for a time kept them at bay; but soon the weight of numbers began to tell, the survivors of the detachment were forced backwards, and at four o’clock the “remnants of the XVIIIth” were ousted from Fort Mulgrave. An hour or two later the French, breaking through the line of fortifications at a second point, carried Mont Faron, a hill 1800 feet high, which from the north partly commands the harbour and the town. On the enemy’s side of this mountain the slopes are steep and rocky; and as much labour had been expended in increasing their natural difficulties, Faron was considered so impregnable that only four hundred and fifty men were employed to guard its two miles of frontage. At daylight every work upon this hill was attacked and, though none of the British posts were driven in, the French poured through the gaps left by the Spaniards and Neapolitans, and established themselves upon the shoulder of Mont Faron from which Toulon is overlooked.
