Forward strode the grenadiers, at great speed but in perfect order, with the best of the Sepoys after them, forward to the base of the Rock, heedless of the spattering fire from above them, forward to the ascent of it, forward without dwelling or firing a shot to the summit; while the enemy, not daring to await the shock of their onset, scrambled headlong down in terror to the plain. Meanwhile Lawrence, with his men in beautiful order, was moving in column round the western side of the Rock, with the design of falling on the left flank of the French battalion. Astruc thereupon changed front to the left to meet him, resting his right flank upon the Rock; but the movement was hardly completed when the British column with admirable precision wheeled into line to its left and halted squarely before him, not more than twenty yards away. Astruc called to his men to reserve their fire till the rest of his troops should deploy and encompass Lawrence's handful of infantry; when to his amazement, for he had not seen the advance of the British grenadiers, a heavy fire from the Rock struck full and true against his right flank and flung it staggering back. The French line wavered. Lawrence's men poured in one crushing volley, and before the French ranks could be closed the British bayonets came gleaming through the smoke, and Astruc's battalion was broken up in hopeless confusion. A few rounds of grape from a British field-gun completed the disorder, and the whole of the French infantry fled for refuge to the rear of the Mysoreans, leaving their guns in the hands of their victors. The Mahratta cavalry dashed forward to cover their retreat, and cut down a few of the British grenadiers who had run forward to secure the captured guns; but they strove in vain to pierce the phalanx of bayonets about the main body and were repulsed with heavy loss. Lawrence halted at the foot of the Rock for three hours, anxious only to renew the fight, and then prepared to retire to his camp, leaving the French to occupy the Golden Rock again if they dared.
