Meanwhile, Devpal, the Rajput king of Chittor's neighbour Kumbhalner, had also become infatuated with Padmavati. While Ratan Sen was imprisoned in Delhi, he proposed marriage to Padmavati through an emissary. When Ratan Sen returned to Chittor, he decided to punish Devpal for this insult. In the ensuing single combat, Devpal and Ratan Sen killed each other. Meanwhile, Alauddin invaded Chittor once again, to obtain Padmavati. Facing a certain defeat against Alauddin, Nagmati and Padmavati along with other women of Chittor committed suicide by mass self-immolation ("jauhar") in order to avoid being captured and to protect their honor. The men of Chittor fought to death against Alauddin, who acquired nothing but an empty fortress after his victory. Khalji's imperial ambitions are defeated by Ratansen and Padmavati because they refused to submit and instead annihilated themselves.
