The Battle of Pollilur was fought on 27 August 1781, between forces of the Kingdom of Mysore under Hyder Ali and British East India Company forces led by General Eyre Coote. The battle was fought on the site of a 1780 encounter in which a Company force was almost completely killed or captured. In the 1781 battle, Coote's troops successfully drove Hyder's force back.
After the battle a shortage of provisions led Coote to move his forces toward Tripasur. Hyder interpreted this as a retreat, and claimed victory.
