The Jhelum River is not just the city's backdrop — it is the reason the city exists, and the reason this particular stretch of the Punjab has been strategically important for more than two thousand years. The Greeks called it the Hydaspes. In 326 BCE, Alexander the Great crossed it in a night march upstream of the main Macedonian camp, bringing his cavalry and infantry across in a pre-dawn operation to outflank the army of King Porus, who had positioned his war elephants along the opposite bank to prevent exactly such a crossing. The battle that followed was the last and hardest of Alexander's campaign — after it, his troops refused to go further east, and the great march turned back at last. The river changed the shape of the known world.
Today the Jhelum flows wide and unhurried through the plains, slowing considerably after its turbulent descent from the mountains of Kashmir and the Pir Panjal range to the northeast. The riverfront is where locals come in the evenings: families, fishermen, and the usual commerce of a Pakistani river town. Fishing boats are drawn up along the banks, and in the late afternoon light the water has a particular quality — glittering and placid — that makes it easy to understand why armies stopped here and why cities grew up on its banks. Walking the riverfront at dusk, when the city is cooling off and the light is right, is the best way to take the measure of a river that once stopped the world's most ambitious conqueror.
