He entered into a compact of friendship with Makhdum ‘Alam, the governor of Hajipur, one of the Amirs of the Wali of Bangala, who despatched an Amir named Qutb Khan to undertake the overthrow of Makhdum ‘Alam. Shir Khan marched to the aid of Makhdum ‘Alam, and after a fierce battle put Qutb Khan to death, taking as spoil elephants and treasure and many followers. Jalal Khan and his tribe, who are Lohanis, in spite of Shir Khan, made over Bihar to the ruler of Bangala and elected to serve under him, and leaving Shir Khan to his fate, took care to secure their own safety. The Bangalis in the first instance sent Ibrahim Khan, the son of the Qutb Khan above mentioned, against Shir Khan to wreak vengeance upon him. Shir Khan used daily to fight with them from within the fort, but since the Bangalis received large reinforcements, and no way of retreat remained open to him, he yielded to necessity and fought a battle with them in the open in which he gained the day. Ibrahim Khan also seeing what had occurred went and joined his father, and Shir Khan seized the whole of the camp of the Bangalis with their elephants and artillery, acquiring thereby great renown, so that he established a lasting and undivided control over the country of Bihar and raised himself to the dignity of a Sultan.
