Meanwhile, Campbell was withdrawing from Lucknow with 3,000 troops and a convoy containing 2,000 sick, wounded and non-combatants who had been evacuated from Lucknow. Hearing that Cawnpore was in danger, he left his infantry to protect the convoy and moved ahead with his cavalry and horse artillery. To his relief, when he arrived on the north bank of the Ganges late on 27 November, the bridge was still intact. Windham held the entrenchment, but the Tantya Tope's army had occupied the city of Cawnpore and the ground between the city and the Ganges.
