France Great Britain Maratha Empire Kingdom of Mysore Rival claimants: Stringer Lawrence Robert Clive Muhammad Ali Khan Wallajah The siege of Trichinopoly (1751–1752) was conducted by Chanda Sahib, who had been recognized as the Nawab of the Carnatic by representatives of the French East India Company, against the fortress town of Tiruchirappalli, held by Muhammed Ali Khan Wallajah.

In an attempt to relieve the siege, the British in Madras sent Captain Robert Clive with a small force to occupy Arcot, which Chanda had left inadequately defended.

Muhammad Ali Khan Wallajah obtained help from Mysorean general Naneraja, Murari Rao of Gooty and Maratha ruler Pratap Singh of Thanjavur.

Two days later he led a sortie against the besiegers, prompting Law to lift the siege and retreat to the isle of Srirangam.
