Their residence in the brisk air of the hills completely restored their health, and they returned to Madras perfectly ready to take part in the great operations which were impending. Charlie, on his return, was appointed to serve as chief of the staff to Colonel Coote; Captain Peters being given the command of a small body of European horse, who were, with a large body of irregulars, to aid in bringing in supplies to the British army, and to prevent the enemy from receiving food from the surrounding country.
Early in June, the British squadron off the coast was joined by two ships of the line, the Norfolk and Panther, from England; and a hundred Europeans, and a detachment of European and native artillery came down from Bombay.
Around Pondicherry ran a strong cactus hedge, strengthened with palisades, and the French retired into this at the beginning of July. They were too strongly posted there to be attacked by the force with which the English at first approached them, and they were expecting the arrival of a large body of troops from Mysore, with a great convoy of provisions.
On the 17th these approached. Major Moore, who was guarding the English rear, had a hundred and eighty European infantry; fifty English horse, under Peters; sixteen hundred irregular horse; and eleven hundred Sepoys. The Mysoreans had four thousand good horse, a thousand Sepoys, and two hundred Europeans, with eight pieces of cannon.
The fight lasted but a few minutes. The British native horse and Sepoys at once gave way; and the English infantry retreated, in great disorder, to the fort of Trivadi, which they gained with a loss of fifteen killed and forty wounded. Peters' horse alone behaved well. Several times they charged right through the masses of Mysorean horse; but when five-and-twenty were killed, and most of the rest, including their commander, severely wounded, they also fell back into the fort.
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.
