Between February 1782 and June 1783, Suffren fought with the British admiral Sir Edward Hughes, and collaborated with the rulers of Mysore. Suffren fought in the Battle of Sadras on February 17, 1782, the Battle of Providien on April 12 near Trincomalee, the Battle of Negapatam on July 6 off Cuddalore, after which Suffren seized upon the anchorage of Trincomalee compelling the small British garrison to surrender. An army of 3,000 French soldiers collaborated with Hyder Ali to capture Cuddalore. Finally, the Battle of Trincomalee took place near that port on September 3. These battles can be seen as the last battles of the Franco-British conflict that encompassed the American War of Independence, and would cease with the signature of the Treaty of Versailles of 1783 establishing peace and recognizing American independence.
