Colonel Coote, when the news of the disaster reached him, determined, if possible, to get possession of the fort of Vellenore, which stood on the river Ariangopang, some three miles from Pondicherry, and covered the approaches of the town from that side. The English encampment was at Perimbe, on the main road leading, through an avenue of trees, to Pondicherry. Colonel Coote threw up a redoubt on the hill behind Perimbe, and another on the avenue, to check any French force advancing from Pondicherry. These works were finished on the morning of the 19th of July. The next morning the French army advanced along the river Ariangopang, but Coote marched half his force to meet them, while he moved the rest as if to attack the redoubts, interspersed along the line of hedge. As the fall of these would have placed the attacking force in his rear, Lally at once returned to the town. The same evening the Mysoreans, with three thousand bullocks carrying their artillery and drawing their baggage, and three thousand more laden with rice and other provisions, arrived on the other bank of the Ariangopang river, crossed under the guns of the redoubt of that name, and entered the town. The fort of Vellenore was strong, but the road had been cut straight through the glacis to the gate, and the French had neglected to erect works to cover this passage. Coote took advantage of the oversight, and laid his two eighteen-pounders to play upon the gate, while two others were placed to fire upon the parapet. The English batteries opened at daybreak on the 16th, and at nine o'clock the whole of the French army, with the Mysoreans, advanced along the bank of the river. Coote at once got his troops under arms, and advanced towards the French, sending a small detachment of Europeans to reinforce the Sepoys firing at the fort of Vellenore. By this time the batteries had beaten down the parapet, and silenced the enemy's fire. Two companies of Sepoys set forward, at full run, up to the very crest of the glacis. The French commander of the place had really nothing to fear, as the Sepoys had a ditch to pass, and a very imperfect breach to mount, and the fort might have held out for two days, before the English could have been in a position to storm it. The French army was in sight, and in ten minutes a general engagement would have begun. In spite of all this, the coward at once hoisted a flag of truce, and surrendered. The Europeans and Sepoys ran in through the gate, and the former instantly turned the guns of the fort upon the French army. This halted, struck with amazement and anger, and Lally at once ordered it to retire upon the town. A week afterwards six ships, with six hundred fresh troops from England, arrived.
