Rani Velu Nachiyar and her daughter Vellachi Nachiyar lived under the protection of Hyder Ali at Virupakshi near Dindigul. Her husband and his second wife were killed by a few British soldiers and the son of the Nawab of Arcot. She escaped with her daughter, lived under the protection of Hyder Ali at Virupachi near Dindigul for eight years. During this period she formed an army and sought an alliance with Gopala Nayaker and Hyder Ali with the aim of attacking the British. In 1780 Rani Velu Nachiyar fought the British and won the battle. When Velu Nachiyar finds the place where the British stock their ammunition, she builds the first human bomb. A faithful follower, Kuyili douses herself in oil, lights herself and walks into the storehouse. Rani Velu Nachiyar formed a woman's army named "udaiyaal" in honour of her adopted daughter — Udaiyaal, who died detonating a British arsenal. Nachiar was one of the few rulers who regained her kingdom and ruled it for 10 more years.
