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.
Still however, the battle raged around it.

The Zouaves, flushed with success, attempted to carry the Round Tower with a rush, and swept up to the abattis surrounding it.

The Russians brought up fresh supports, and the whole hill-side was alive with the flicker of musketry.
