The Battle of Chinhat:The Battle of Chinhat was fought on the morning of 30 June 1857, between British forces and Indian rebels, at Ismailganj, near Chinhat, Oude (Awad/Oudh). The British were led by The Chief Commissioner of Oude, Sir Henry Lawrence. On approaching Ismaelganj, Lawrences's force was suddenly fired on by the insurgents. The rebels were in well-prepared positions, behind stone walls, and in the village, and soon inflicted heavy casualties on Lawrence's force. The regiment's acting commanding officer, Lieutenant Colonel William Case, was killed. To the latter fact may be attributed one of the few major victories which rebel forces obtained in open combat with the British, during the whole of the 'Mutiny'. At a crucial moment, many of Lawrence's soldiers, especially Indian artillerymen, betrayed him by going over to the other side, overturning their guns and cutting the traces on the horses. A charge by the 36 volunteer cavalrymen, consisting partly of civilians, threw the rebel cavalry into confusion and a significant part of the force was able to cross the bridge and retreat towards Lucknow. Lawrence ordered a battery of European artillery to occupy the bridgehead, with the intention of dissuading his enemy from following him. The artillery had no ammunition left but achieved their aim of giving the retreating force a breathing space. ?Hence, the correct answer is 30 June 1857.
