Which of the following ancient literary sources provides detailed accounts of Alexander's invasion of the Punjab region and his encounter with King Porus?

💡 Solution & Explanation

The Anabasis of Alexander written by the Greek historian Arrian is considered the most reliable and comprehensive account of Alexander the Great's military campaigns including his crossing of the Indus and the Battle of Hydaspes against King Porus in Punjab. While Megasthenes wrote about the Mauryan administration, Arrian specifically chronicled the Macedonian expedition using primary records from Ptolemy and Aristobulus. The Hydaspes campaign marked the easternmost limit of Alexander's conquests.
