As usual, they had scattered themselves over the country and entirely disappeared, and many of the rebels who still remained in the city seized the opportunity of the Cavalry being absent to get away.
Outram's command on the left bank of the Gumti was now broken up, with the view to his completing the occupation of the city.

Accordingly, on the 16th, he advanced from the Kaisarbagh with Douglas's brigade[14] and Middleton's battery, supported by the 20th Foot and Brasyer's Sikhs, and occupied in quick succession, and with but slight resistance, the Residency, the Machi Bhawan, and the great Imambara, thus taking in reverse the defences which had been thrown up by the enemy for the protection of the two bridges.

As Outram pushed on, the rebels retreated, some across the stone bridge towards Fyzabad, and some through the city towards the Musabagh.

They made two attacks to cover their retirement, one on Walpole's piquets, which enabled a large number (20,000 it was said) to get away in the Fyzabad direction, and another on the Alambagh, which was much more serious, for the garrison had been reduced to less than a thousand men, and the rebels' force was considerable, consisting of Infantry, Cavalry and Artillery.

They attacked with great determination, and fought for four hours and a half before they were driven off.
It was not a judicious move on Sir Colin's part to send the Cavalry miles away from Lucknow just when they could have been so usefully employed on the outskirts of the city.
