General Thomas Arthur, comte de Lally‘s French army, including his regiment of the Irish Brigade, is defeated on January 22, 1760 in the Battle of Wandiwash, a decisive battle in India during the Seven Years’ War, by Irish-born Sir Eyre Coote‘s British army. Wandiwash is the Anglicised pronunciation of Vandavasi.
When Lally is selected as commander-in-chief of the French expedition to India in 1756, he is one of the greatest living soldiers of France. Lally’s force is delayed and does not leave France until May 1757. Further delays occur en route and he finally lands at Pondicherry, India, on April 28, 1758. In less than two months, Lally clears the English forces from a huge area around Pondicherry and captures almost 300 pieces of artillery. Lally next lays siege to Madras, but his naval support abandons him and, in January 1759, the English are reinforced, forcing Lally to retire toward Pondicherry. Forces away from India are conspiring against Lally now, as the merchant fleets of the French have been rendered useless by the English navy.
Lally’s army, burdened by a lack of naval support and funds resulting in his troops having not been paid in six months, attempts to regain the fort at Wandiwash, now in Tamil Nadu. He is attacked by Sir Eyre Coote’s forces and decisively defeated. The French general Marquis de Bussy-Castelnau and the French are then restricted to Pondicherry where, facing starvation, they surrender on January 16, 1761.
This is the Third Carnatic War fought between the French and the British. Having made substantial gains in Bengal and Hyderabad, the British, after collecting huge amount of revenue, are fully equipped to face the French in Wandiwash, whom they defeat.
According to the 19th century book Annals of the Wars of the Eighteenth Century by Author Eduard Cust, the French Army consists of 300 European Cavalry, 2,250 European infantry, 1,300 soldiers, 3,000 Marathas and 16 pieces of artillery while the English deploy about 80 European Horses, 250 Native horses, 1,900 European Infantry, 2,100 soldiers and 26 pieces of artillery. The Battle of Wandiwash involves the capture of Chettupattu, Thiruvannamalai, Tindivanam and Perumukkal.
