The fire of the allied batteries soon obtained a mastery, and the Mamelon especially was in ruins. Todleben, speaking of the bombardment, said that more terrific than all else was the fire of the English.[37] It was arranged that the assault of the Russian advanced works should take place shortly before sunset, and during the afternoon of the 7th the French columns, in the highest spirits, marched under cover and unobserved down the ravines in readiness. The signal was given about half-past six, and the French first attacked and occupied the _ouvrages blancs_, near the Careening Bay ravine, taking several hundred prisoners. They then assaulted the Mamelon, took it with great rapidity and comparative ease, and hoisted their flag on the work; but, led away by success, they impetuously, and contrary to the intention, followed the enemy even up to the glacis of the Malakoff. The Russians, however, came out in great force, and not only drove back the French columns, but followed them into the Mamelon and recaptured it, the French retreating down the slopes in disorder and with great loss. It was a critical moment, but Pélissier was equal to the occasion. Having large reserves in the adjoining ravine, he at once sent them forward and for a second time occupied the great outwork; and, darkness coming on, its entrenchments were turned during the night and the position firmly held. At the same time, whilst these serious battles were taking place, the English troops, consisting of part of the Light and Second Divisions, stormed the quarries in front of the Redan in the most brilliant manner; and although they were furiously attacked several times during the night by sorties from the Russian adjacent works, and suffered great loss, they resisted all efforts to dislodge them, and the next morning found them firmly established in comparatively close proximity to the Redan.
