A site south of the fourth cataract of the Nile in NUBIA, modern Sudan, where TUTHMOSIS I (r. 1504–1492 B.C.E.) campaigned against several groups of Nubians. The Nile altered its course just north of Abu Hamed, complicating troop movements and defenses. Tuthmosis I used veteran soldiers and local advisers to establish key positions and defensive works in order to gain dominance in the region.
