The powder-bags were laid at the Cashmere gate by Lieutenants Home and Salkeld.  The explosion followed, and the third column rushed in, and pushed toward the Jumna Musjid.  Meanwhile the first column under Nicholson escaladed the breaches near the Cashmere gate, and pushed along the ramparts toward the Kabul gate, carrying the several bastions in the way.  Here it was met by the second column under Brigadier Jones, who had escaladed the breach at the Water bastion.

The advancing columns were met by a ceaseless fire from terraced houses, mosques, and other buildings; and John Nicholson, the hero of the day, while attempting to storm a narrow street near the Kabul gate, was struck down by a shot and mortally wounded.  Then followed six days of desperate warfare.  No quarter was given to men with arms in their hands; but women and children were spared, and only a few of the peaceable inhabitants were sacrificed during the storm.

On September 20th the gates of the old fortified palace of the Moguls were broken open, but the royal inmates had fled.  No one was left but a few wounded sepoys and fugitive fanatics.  The old King, Bahadur Shah, had gone off to the great mausoleum without the city, known as the tomb of Humayun.  It was a vast quadrangle raised on terraces and enclosed with walls.  It contained towers, buildings, and monumental marbles in memory of different members of the once distinguished family, as well as extensive gardens, surrounded with cloistered cells for the accommodation of pilgrims.

On September 21st Captain Hodson rode to the tomb, arrested the King, and brought him back to Delhi with other members of the family, and lodged them in the palace.  The next day he went again, with one hundred horsemen, and arrested two sons of the King in the midst of a crowd of armed retainers, and brought them away in a native carriage.  Near the city the carriage was surrounded by a tumultuous crowd; and Hodson, who was afraid of a rescue, shot both princes with his pistol, and placed their bodies in a public place for all men to see.

Thus fell the imperial city; captured by the army under Brigadier Wilson before the arrival of any of the reenforcements from England.  The losses were heavy.  From the beginning of the siege to the close, the British army at Delhi had nearly four thousand killed and wounded.  The casualties on the side of the rebels were never estimated.  Two bodies of sepoys broke away from the city and fled down the valleys of the Jumna and Ganges, followed by two flying columns under Brigadiers Greathed and Showers.  But the great mutiny and revolt at Delhi had been stamped out, and the flag of England waved triumphantly over the capital of Hindustan.

The capture of Delhi, in September, 1857, was the turning-point in the sepoy mutinies.  The revolt was crushed beyond redemption; the rebels were deprived of their head centre; and the Mogul King was a prisoner at the mercy of the power whom he had defied.  But there were still troubles in India.  Lucknow was still beleaguered by a rebel army, and insurrections still ran riot in Oudh and Rohilkhand.
