What happened
The rebellion against East India Company rule broke out at Meerut in May 1857 and spread rapidly across northern and central India, with its main centers at Delhi, Cawnpore, Lucknow, Jhansi, and Gwalior. Delhi, in the National Army Museum's account, became the center of the uprising because it was the seat of Bahadur Shah Zafar, the old and largely powerless Mughal emperor; the mutineers from Meerut went there immediately to seek his backing, which he gave reluctantly. British forces spent from June to September 1857 trying to retake the city, holding a ridge overlooking Delhi against more than 30,000 rebels through the summer heat and cholera outbreaks before reinforcements under Brigadier-General John Nicholson arrived in August with a siege train of 32 guns. The final assault came on 14 September, breaching the walls at the Kashmir Gate, and after a week of street fighting the city fell on 21 September; it was then ransacked in what the museum's account calls an orgy of looting and killing.
Why it matters
By lending his name and his palace to the rebellion, however unwillingly, Bahadur Shah Zafar gave the uprising a legitimizing figurehead that made Delhi's recapture the single most important British military priority of the war, and its fall was the decisive factor in suppressing the rebellion elsewhere. The scale of the reprisals that followed the city's capture, including executions carried out without trial, shows how completely the British treated the old emperor's court as the rebellion's political center rather than a bystander.
How we know
The siege of Delhi is documented in British military dispatches and eyewitness accounts from soldiers present, including officers under Nicholson's command; the National Army Museum's institutional history draws directly on these regimental and campaign records.
