Indian Rebellion of 1857

The Meerut garrison mutinies and frees the imprisoned cavalrymen

The evening after 85 cavalrymen were degraded, shackled and marched to jail in front of the garrison, their comrades broke them out.

Sunday evening, 10 May 1857, at Meerut

On the evening of Sunday, 10 May 1857, Company troops of the 3rd Bengal Light Cavalry and the 11th and 20th Bengal Native Infantry mutinied at Meerut.

Men of the 3rd Light Cavalry broke 85 imprisoned comrades out of jail. Those men had been convicted after refusing cartridges they believed violated their religions — 80 sentenced to ten years, five to five.

The provocation was the punishment

The disputed cartridge drill, ordered by Lieutenant-Colonel George Carmichael-Smyth, had taken place on 24 April. What detonated on the 10th was the spectacle of the previous day, when the 85 were publicly degraded, shackled and marched to jail.

The mutineers attacked the military station, killed British officers and civilians, burned buildings and opened the jails. Colonel John Finnis of the 11th Native Infantry was killed while trying to address and restrain them.

Forty miles to Delhi

The British command at Meerut failed to stop or promptly pursue the departing rebels, who set out on the roughly 40 miles to Delhi.

They arrived on 11 May, and the city fell to them, moving the revolt onto a far larger political footing at the Mughal capital. Bahadur Shah Zafar was drawn into its leadership only after they reached him there.

Calling Meerut the beginning is conventional but imprecise: the 19th Native Infantry had already resisted at Berhampore, and Mangal Pandey attacked officers at Barrackpore on 29 March.

What the sources leave uncertain

May 10 is securely documented and uses the Gregorian calendar employed by British authorities.
Calling Meerut the absolute 'beginning' is conventional but imprecise. The 19th Native Infantry had resisted at Berhampore, and Mangal Pandey attacked officers at Barrackpore on March 29. Meerut was the outbreak that began the rebellion 'in earnest' or its first sustained large-scale action.
Accounts differ on the exact sequence of violence among the 3rd Cavalry, the two infantry regiments, local crowds, and released prisoners; the three Company regiments all participated.
