Babur's success did not end here. The fortress of Raberi on the Yamuna was soon after abandoned by its garrison and occupied by his troops, and he sent detachments to besiege Etawah and Dholpur, two places of the greatest importance from their vicinity to Agra.[citation needed] But these initial victories brought him in direct conflict with the Western and Eastern Afghan confederates at once.[citation needed] Babur then sent an army under his son Humayun who would put to flight the army of the Eastern confederates and take Jaunpur, Oudh, and Kalpi.[citation needed]
