The British army’s siege and recapture of Delhi from rebel Indian forces between June 8 and September 21, 1857, was a decisive moment in its efforts to suppress the uprising against British control that broke out in northern India in early 1857. The British victory extinguished the rebels’ dreams of re-creating the rule of the Mughal Empire, and it enabled British forces to defeat remaining resistance. The battle would prove to be one of the important early events in the Indian Independence Movement.

In April 1857, Indian soldiers under British officers at Meerut were jailed for refusing to use new rifles that, they believed, forced them to violate their religious beliefs. This punishment provoked other soldiers at Meerut, about 35 miles from Delhi, to kill their officers and then march on Delhi and capture it in May, recruiting the garrison there and massacring dozens of British men, women, and children living in the city. The British were unable to launch a counterattack because their army was dispersed over vast distances. It took quite some time for the British to assemble a force sufficient to recapture the city, but, in June, two columns were combined with a force of Gurkhas.

The makeshift force managed to occupy a ridge overlooking Delhi but was not large enough to launch an assault, marking the beginning of the siege on June 8. Inside the city was Bahādur Shah II, holding court as the Mughal emperor. He had been reluctant to wage war against the British until the Indian soldiers in the city who were loyal to him forced his hand. Facing as many as 40,000 rebel fighters, the British force felt as though they were the ones under siege, and, as the weeks wore on, the British began to suffer from outbreaks of cholera and dysentery. However, reinforcements slowly arrived from the Punjab, including a siege train of 32 guns and 2,000 more men under the command of Brigadier General John Nicholson.

By early September, the British had assembled a force of some 9,000 men, which consisted of 3,000 regular troops and 6,000 Sikhs, Punjabis, and Gurkhas. The siege guns begun firing on September 8 and, by September 14, had made sufficiently large breaches in the walls to launch an attack. The assault, led by Nicholson, met with stiff resistance; in a clash at the Cashmere (Kashmiri) Gate leading into the city, Nicholson was mortally wounded, but his troops were able to break through their opponents’ defenses. By September 21, after a week of savage street-to-street fighting and numerous atrocities committed in the name of avenging the massacre carried out by rebel forces some five months earlier, Delhi was back under British control. Bahādur Shah was arrested and died in exile in what is today Yangon, Myanmar, in 1862. He was the last of the Mughal emperors.

Losses: British, 1,200 dead, 4,600 wounded of 9,000; Indian, 5,000 dead or wounded of 40,000.
