From 1744, the French and English fought a series of Battles for supremacy in the Carnatic region. In the third Carnatic war, the British East India Company defeated the French forces at the battle of Wandiwash ending almost a century of conflict over supremacy in India. This Battle gave the British trading Company a far superior position in India compared to the other Europeans.
The Battle of Wandiwash was a decisive battle in India during the Seven Years' War. The Count de Lally's army, burdened by a lack of naval support and funds, attempted to regain the fort at Vandavasi near Pondicherry. He was attacked by Sir Eyre Coote's forces and decisively defeated. The French general Marquis de Bussy-Castelnau and the French were then restricted to Pondicherry, where they surrendered on 16 January 1761. Wandiwash is the Anglicised pronunciation of Vandavasi.
This was the Third Carnatic War fought between the French and the British. After making substantial gains in Bengal and Hyderabad, the British, after collecting huge amount of revenue, were fully equipped to face the French in Wandiwash. Thus, they defeated the French comprehensively in this Battle.
According to the 19th century book ("Annals of the wars of the eighteenth century") by Author Eduard Cust, the French Army has used 300 European Cavalry, 2250 European Infantries, 1300 Sepoys, 3000 Mahrattas with 16 pieces of Artillery and the English had used about 80 European Horses, 250 Native horses, 1900 European Infantries, 2100 Sepoys and 26 pieces of Artillery.. Battle of Wandiwash involved capture of Chetpattu (Chengalpattu), Tirunomalai(Thiruvannaamalai), Tindivanam and Perumukkal.
