In the queen's army, she quickly rose in the ranks and began commanding her own army. During the Rebellion of 1857, General Hugh Rose attacked Jhansi with a large army. The queen faced the army with 14,000 of her troops. She waited for relief from Peshwa Nana Sahib's army camping at Kalpi that did not come because Tantia Tope had already been defeated by General Rose. Meanwhile, Dulha Ju, in charge of one of the gates of the fort, had made a pact with the assailants and opened the doors of Jhansi for the British forces. When the British rushed the fort, Laxmibai, on advice of her courtier, escaped through Bhanderi gate with her son and attendants to Kalpi. Upon hearing of Laxmibai's escape, Jhalkaribai set out for General Rose's camp in disguise and declared herself to be the queen. This led to a confusion that continued for a whole day and gave the Rani's army renewed advantage.
