The History of Shēr Shāh (Tārīkh-i Shērshāhī) 3.15.2

3.15.2

Khawds Khdn also, who had been sent against Maharta, was summoned to come with all speed. The Emperor, on receiving Sher Khdn's missive, agreed to give him the kingdom of Bengal, but on condition that whereas he had transgressed his boundaries, and had encamped himself in face of the Emperor on the other side the stream, he should show his respect to the Emperor by retreating, and leaving the passage of the river free to the Emperor; and that when the Emperor Humayun had crossed, he would march two or three marches in the track of Sher Khdn, and then turn back. Sher Khdn agreed to these conditions, and leaving the passage of the river free, retraced his march. The Emperor bridging the river, crossed it with his whole camp and army and family, and pitched on the further side. He then sent Shaikh Khalil, a descendant of Shaikh Farld Shakar-ganj (the pole of the world), on an embassy to Sher Khan, to urge him to march by regular stages back to Eohtds, and to delay nowhere, and to promise that the Emperor, after making some marches in his rear, would turn aside, and after that would give, as he had agreed, to Sher Khdn's agent, a farmdn for the kingdom of Bengal. When Shaikh Khalil came to Sher Khan, he told him what the Emperor had said. Sher Khan ostensibly agreed to this arrangement, and received him with all honour and hospitality; nor did he omit the slightest point of customary etiquette.
