Acesines: one of the main rivers in the Punjab, modern Chenab.
In the early summer of 326, the army of Alexander the Great crossed the river somewhere between Chenab and Guhrat. This was not the main road (which was, then and now, the Grand Trunk Road): Alexander had decided to take a more northern route.The monsoon had started early that year, and besides, the snows of the Himalaya were melting. The historian Arrian of Nicomedia mentions that crossing was difficult because the waters were swift and violent (Anabasis, 5.20.8). It may have been about three kilometers wide, which is certainly not impossible. Dangerous rocks and torrents are also mentioned. Pliny the Elder says that the Indian cane (bamboo) on the boards of the Acesines was something special - we do not know why.note[Pliny the Elder, Natural History 16.61.] In Antiquity, the Chenab passed along Lahore, which may have been the capital of the dynasty of Alexander's opponent Porus; however that may be, the river was the eastern frontier of his kingdom, the Jhelum (ancient Hydaspes) being the western border.
The Acesines expanded its size with the waters of the rivers Jhelum and Ravi (Hydraotes). It was already a very wide river when it passed Multan. Near modern Uch, ancient Alexandria, it accepted the waters of the Sutlej (Hyphasis), and finally, the big river emptied itself in the mighty Indus. The confluence is called "Head of the Punjab", and the stream can be six kilometers wide.
