v3.c41.s2.16

Early in the 17th century, the Mughals, after annexing Koch Hajo (1612), had a long war with the Ahoms, who had harboured a prince of the deposed dynasty. At last in 1638 a peace was made, by which the Muhammadans were allowed to retain the country west of the Bar Nadi in the north Brahmaputra valley, and west of the Asurar Ali in the region south of that great river.*
