Explanation:

In October 1802, the combined armies of Peshwa Baji Rao II and Scindia were defeated by Yashwantrao Holkar, ruler of Indore, at the Battle of Poona. Baji Rao fled to British protection, and in December the same year concluded the Treaty of Bassein with the British East India Company, ceding territory for the maintenance of a subsidiary force and agreeing to treaty with no other power. The treaty would become the "death knell of the Maratha Empire".
