Between February 1782 until June 1783, Suffren fought the English 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 (1782) 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 in 1783 with the signature of the 1783 peace treaty.
