[citation needed] After the fall of Srirangapattana and death of Tipu Sultan on 4 May 1799, Shezada Hyder Ali and other family members were sent to the Vellore fort on 19 June 1799 and kept under custody of the East India Company.
[1] However, they failed to close the gates of the fort securely, and a British officer escaped and alerted the garrison in Arcot.
Nine hours later, the British 19th Light Dragoons, led by Colonel Rollo Gillespie, and the Madras Cavalry recaptured the fort.
Some accounts state that 17 Indian officers were hanged in public and many were imprisoned at the Vellore and Tiruchi prisons.
Today, many of Shezada Hyder Ali's descendants live in Calcutta, Karnataka, Andhra Pradesh, and Sydney (Australia).
