If, however, prophecies and omens alike appeared to favour the rebels, fortune was not altogether unkind to us, for on the 22nd a reinforcement reached Rhai, twenty-two miles from Delhi, consisting of six Horse Artillery guns, a small party of British Infantry, a squadron of the 2nd Punjab Cavalry, and the Head-Quarters of the 4th Sikhs, numbering in all about 850 men.
A staff officer was sent at once to Rhai to hurry on the force and tell them how urgently their assistance was required in camp; this appeal was responded to with the utmost alacrity, and early the next evening the welcome reinforcement made its appearance.
It had scarcely arrived before the Artillery on the city walls opened fire, while guns, which had been brought into the suburbs, enfiladed our right and concentrated a heavy fire on Hindu Rao's house which the few guns we had in position were quite unable to silence.

The rebel Infantry occupied Kishenganj and Sabzi Mandi in force, and threatened to advance on the Mound battery, while a constant musketry fire was maintained upon the Ridge.

Reid reported that the mutineers made a desperate attack at about twelve o'clock, and that no men could have fought better; they charged the Rifles, the Guides, and the Gurkhas again and again.

The cannonade raged fast and furious, and at one time it seemed as though the day must be lost.

Thousands were brought against a mere handful of men; but Reid knew the importance of his position, and was determined at all hazards to hold it until reinforcements arrived.[18] The mutineers were checked, but not driven off.
