Onao (Indian Mutiny).

Fought July 28, 1857, between Havelock's relieving force, 1,500 strong, and the rebels, who occupied a strong position near Onao, so protected on the flanks that a frontal attack was necessary. This was successful, and after the town had been passed, a further attack by the mutineers was repulsed, with a loss of 300 men and 15 guns.
