Taxiles
Taxiles (in Greek Tαξίλης or Ταξίλας; lived 4th century BC) was the Greek chroniclers' name for the ruler who reigned over the tract between the Indus and the Jhelum (Hydaspes) Rivers in the Punjab region at the time of Alexander the Great's expedition. His real name was Ambhi (Greek: Omphis), and the Greeks appear to have called him Taxiles or Taxilas, after the name of his capital city of Taxila, near the modern city of Attock, Pakistan. Life

Ambhi ascended to throne of Takshasila. He sent an embassy to Alexander along with presents consisting of 200 Talents of silver, 3,000 fat oxen and 10,000 sheep or more ( both are estimated around 600 talents of silver)a force of 700 horsemen and offered for surrender. He appears to have been on hostile terms with his neighbour, Porus, who held the territories east of the Hydaspes. It was probably with a view to strengthening himself against this foe that he sent an embassy to Alexander, while the latter was still in Sogdiana, with offers of assistance and support, perhaps in return for money. Alexander was cautious by the sight of Ambhi's forces on his first descent into India in 327 BC and ordered his own forces to form up. Ambhi hastened to relieve Alexander of his apprehension and met him with valuable presents, placing himself and all his forces at his disposal. Alexander not only returned Ambhi his title and the gifts but he also presented him with a wardrobe of "Persian robes, gold and silver ornaments, 30 horses and 1000 talents in gold". Alexander was emboldened to divide his forces, and Ambhi assisted Hephaestion and Perdiccas in constructing a bridge over the Indus where it bends at Hund (Fox 1973), supplied their troops with provisions, and received Alexander himself, and his whole army, in his capital city of Taxila, with every demonstration of friendship and the most liberal hospitality. On the subsequent advance of the Macedonian king, Taxiles accompanied him with a force of 5000 men and took part in the Battle of the Hydaspes. Later Eudemus took over Taxila briefly, after which Chandragupta Maurya conquered Alexander's satraps in the sub-continent by 317 BC.
