Raja Ambhi
Alexander moved from Taxila of Raja Ambhi, whom he subdued without fight, to Kalar Kahar. From there he moved over the Salt Range, turning left, along the western bank of River Jhelum, which he called Hydaspes. Opposite him on the other bank was a Raja Porus. They fought Alexander's biggest Indian battle which Alexander won, achieving a masterly surprise against the valiant Rajput. Before moving further, along the river Alexander established a village on west bank of the River and ordered construction of 2000 boats. Greek Admiral Nearches was to arrange wood from nearby higher hills which would be floated down the River and hauled up at this point. He called this village as Boucephila (present-day Jhelum City). The Jhelum River passes vying with the residential areas of the city.
The mosque inside the river is a famous landmark most commuters on the Grand Trunk Road even today. Alexander's Naval Chief was assigned the task of boats building on a very large scale. Therefore, the craftsmen on a large scale were gathered, hence the modern colonies in the city were named as Machine Mohallahs (Number 1, 2 and 3), because of saw mills. Jhelum became timber market for whole of Punjab over the millenniums. It was only after construction of Mangla Dam that log wood does not float down the river and the city has lost this privilege. There is a plywood factory also, which is flourishing. Greeks left marks of their chivalry and martial spirit which mixed up well with the races and clans dwelling in the area.
