The army took up a new position on the 5th of April, and in the evening the TWELFTH regiment was ordered to advance, supported by two battalions of Sepoys, and take possession of a nullah, or bed of a river or aqueduct, about a mile and a half in front of the camp. The night was very dark, but the regiment had scarcely cleared the outposts, when the air was illuminated by hundreds of fire-balls thrown up by the enemy, who thus detected the advance of the British troops, and immediately commenced a heavy fire of musketry and rockets, under which the TWELFTH continued to advance in open column of companies. Suddenly, regular platoon firing was heard in front, and showers of bullets assailed the regiment on both flanks and in front, when it formed line. The trampling sound of approaching troops occasioned the regiment to prepare to charge with the bayonet, which was about to be executed, when it was discovered that the approaching troops were one of the battalions of Sepoys which had been ordered to support the TWELFTH. This battalion had lost its road, moved to the front, and become exposed to the attack of very superior numbers of the enemy, whom it had engaged upwards of an hour, which accounted for the platoon firing heard in front; it was retreating, bringing off its killed and wounded, under Major Colin Campbell, and being pursued, formed in the rear of the TWELFTH regiment. When the pursuing Mysoreans discovered, by their fire-balls, the line of Europeans before them, they fell back to a greater distance, but without any relaxation in their fire, and so many spent balls struck the officers and soldiers of the TWELFTH, that they were ordered to sit down to await the approach of day for the completion of the enterprise; the nullah was at some distance, and it could only be approached by a road of difficult access. The regiment did not fire a shot, but large quantities of ammunition were sent from the camp; the incessant firing having given rise to the expectation that the soldiers must have expended their cartridges.
