In 327 BC, Greece goes head-to-head with India in Alexander the Great’s final campaign. As Alexander leads his armies into India, he faces one of the most difficult tactical challenges any ground commander can confront–a forced river-crossing, a raging thunder storm and a vicious enemy. Alexander is able to deceive the Indian General Porus into believing that they would not attempt a crossing, instead he maneuvers his infantry across the river at night–catching the Indian Legions unaware. Victory is at hand thanks to this strategic brilliance.
