and a period of military skirmishes and political intrigues began and continued even in rare periods when France and Great Britain were officially at peace. Under the command of the Marquis de Bussy-Castelnau, Dupleix's army successfully controlled the area between Hyderabad and Cape Comorin. But then Robert Clive arrived in India in 1744, a British officer who dashed the hopes of Dupleix to create a French empire in India. After a defeat and failed peace talks, Dupleix was summarily dismissed and recalled to France in 1754. French vs British intrigues (1754-1871) In spite of a treaty between the British and French agreeing not to interfere in regional Indian affairs, their colonial intrigues continued. The French expanded their influence at the court of the Nawab of Bengal and increased their trading activity in Bengal. In 1756, the French encouraged the Nawab (Siraj ud-Daulah) to attack and take the British Fort William in Calcutta. This led to the Battle of Plassey in 1757, where the British decisively defeated the Nawab and his French allies, resulting in the extension of British power over the entire province of Bengal. Subsequently, France sent Lally-Tollendal to recover the lost French possessions and drive the British out of India. Lally arrived in Pondichéry in 1758, had some initial success and razed Fort St. David in Cuddalore District to the ground in 1758, but strategic mistakes by Lally led to the loss of the Hyderabad region, the Battle of Wandiwash and the siege of Pondicherry in 1760. In 1761, the British razed Pondichéry to the ground in revenge for the French depredations; it lay in ruins for four years. The French had lost their hold now in South India too. In 1765, Pondichéry was returned to France in accordance with a 1763 peace treaty with Britain. Governor Jean Law de Lauriston set to rebuild the town on its former layout and after five months 200 European and 2000 Tamil houses had been erected. In 1769, the French East India Company, unable to support itself financially, was abolished by the French Crown, which assumed administration of the French possessions in India. During the next 50 years, Pondichéry changed hands between France and Britain with the regularity of their wars and peace treaties. In 1816, after the conclusion of the Napoleonic Wars, the five establishments of Pondichéry, Chandernagore, Karaikal, Mahe and Yanam and the lodges at Machilipatnam, Kozhikode and Surat
