In the spring of 327 B. C., Alexander marched through what is now
Afghanistan, crossed the Indus, and defeated an Indian king, Porus, on
the banks of the Hydaspes (the Jhelum). On his way to the Indus he
stormed the capital of an Indian tribe, now Mooltan, and was himself
severely wounded. In 326 he sailed in a fleet, built on the spot, down
the Indus, into the ocean; despatched a part of the army on board the
ships, under his admiral Nearchus, by sea coastwise into the Persian
Gulf, and marched himself with the rest through what is now Beluchistan,
reaching Susa early in 325 B. C.
