It was only a few days after the marriage that this mutiny broke out. Zuffer, with a body of troops, rushed into Serdhauna, seized the town, and was proclaimed Jaghire Dar. The Begum vainly endeavoured to pacify her soldiers. She was arrested, together with her husband, and thrown into prison; and Le Vaissaux, too proud to sue for mercy, put an end to his own life. In the course of the following year, the Begum, who had been ever since kept in durance vile, besought the assistance of George Thomas, for, said she, the hourly dread of assassination was driving her mad. Thomas was not deaf to her entreaties; he persuaded Bappoo, a Mahratta chief, to aid him with his forces, and together they marched upon Serdhauna. The Mahrattas were won over, partly by the prayers of Shah Aulem, and partly by liberal promises; and Zuffer having been expelled, the Begum was restored to power. Begum Sumroo was a good friend to the English, with whom she was always exceedingly popular on account of the great hospitality with which she entertained those who visited her neighbourhood. However, she fought against them, as an auxiliary of Scindiah, in 1803. She took part in the battle of Assaye; and at the defeat of the Mahrattas, she fled to Northern Hindostan, and hastily made peace with the Marquis Wellesley, on condition that her principality should revert to the British Government of India after her demise, while her personal property remained at her own disposal. When the British became masters of Delhi, the Begum frequently visited their camp, dressed in European costume, with a hat and veil, sometimes in a palanquin, sometimes on horseback, sometimes on an elephant. At this time she appeared to be about fifty-five, was of middle height, with a beautiful complexion. Her ancient friendship for the Mahrattas, and an intercepted letter which she was believed to have written to Jeswunt Rao Holkar, caused her to be suspected by the British when they were at war with that chief in 1805. However, she succeeded in clearing herself of the accusation. The exact year of her death is not known.
