Despite not being in command, Nicholson immediately began inspecting the British positions and formulating his plan to capture the city. It did not take long for Nicholson to come to the conclusion that Wilson "was not at all equal to the crisis" and would not be able to command the assault on the city. Wilson's strategy was based upon waiting for the arrival of a siege train from Calcutta before he would launch the assault. However, the rebels dispatched a 6,000 strong force from Delhi to intercept the British train before it could reach the city.
