On the morning after his arrival all was expectation, for it was known that the bombardment was about to recommence. At half-past two o'clock the roar of 157 guns and mortars in the British batteries, and over 800 in those of the French, broke the silence, answered a minute or two later by that of the Russian guns along their whole line of batteries. The day was hot and almost without a breeze, and the smoke from so vast a number of guns hung heavily on the hill-side, and nothing could be seen as to the effect which the cannonade was producing. It was not until next morning that the effect of the fire was visible. The faces of the Russian batteries were pitted and scarred, but no injury of importance had been inflicted upon them. All day the fire continued with unabated fury on the side of the allies, the Russians replying intermittently. Presently the news circulated through the camp that an assault would be made at six o'clock, and all officers and men of duty thronged the brow of the plateau, looking down upon the town.
At half-past six a body of French troops were observed to leave their trenches, and, in skirmishing order, to make their way towards the Mamelon. The guns of the Russian fort roared out, but already the assailants were too close for these to have much effect. Soon a great shout from the spectators on the hill proclaimed that the Zouaves, who always led the French attacks, had gained the parapet. Then, from within, a host of figures surged up against the sky, and a curious conflict raged on the very summit of the work. Soon, however, the increasing mass of the French, as they streamed up, enabled them to maintain the footing they had gained, and pouring down into the fort, they drove the Russians from it, the French pouring out in their rear. Twice fresh bodies of Russian reserves, coming up, attempted to roll back the French attack; but these, exultant with success, pressed forward, and, in spite of the fire which the guns of the Round Tower fort poured upon them, drove their enemies down the hill. It was growing dark now, and it could with difficulty be seen how the fight was going. Fresh masses of French troops poured from their advance trenches into the Mamelon, and there was no question that that point was decidedly gained.
