Attack on Gwalior Contingent by Windham’s force In November 1857, when Sir Colin Campbell was busy in the relief of Lucknow Residency, Tatya Tope advanced on Kanpur at the head of the Gwalior Contingent of which he had assumed command at Kalpi. General Windham who had been left at Kanpur for the defence of the city attacked Tatya Tope’s force on 26 November. Next day the Maratha leader routed Windham’s force and on 28 November the English commander was obliged to take shelter in the entrenchment. Pursuit of the Gwalior Contingent by Sir Colin Campbell Tatya Tope’s success at Kanpur was short-lived as Sir Colin Campbell soon returned to the city. On 6 December the English Commander-in-Chief attacked and defeated Tatya's troops and they fled towards Kalpi pursued by Sir Colin's force.
