In short
In May 326 BC, Alexander the Great's Macedonian army crossed the Hydaspes River to face Indian king Porus and his forces in what became one of antiquity's most decisive battles. Alexander's tactical use of cavalry and infantry won the day, but Porus's resistance demonstrated that even the young conqueror could be challenged. The victory opened the Punjab to Macedonian control and marked a turning point in Alexander's eastward campaign.
How it unfolded.
The five-minute version
What actually happened.
The Battle of the Hydaspes also known as Battle of Jhelum, or First Battle of Jhelum, was fought between the Macedonian Empire under Alexander the Great and the Pauravas under Porus in May of 326 BC. It took place on the banks of the Hydaspes River in what is now the Punjab province of Pakistan, as part of Alexander's Indian campaign. In what was possibly their most costly engagement, the Macedonian army secured a decisive victory over the Pauravas and captured Porus. Large areas of Punjab were subsequently absorbed into the Macedonian Empire; Alexander spared Porus and made him a satrap, effectively reinstating him as the region's ruler.

Timeline
How it actually unfolded.
Alexander approaches the Hydaspes
The Macedonian army reaches the eastern bank of the Hydaspes River, where Porus has positioned his forces on the opposite bank to block crossing.
River crossing begins
Alexander executes a flanking maneuver, sending cavalry and infantry units across the river at night to avoid direct confrontation with Porus's main force.
Battle of the Hydaspes
The two armies meet in open field combat. Alexander's cavalry, under Coenus, strikes Porus's war elephants and forces from the flank, breaking the Indian line. Porus's son is killed in fighting.
Macedonian victory confirmed
Porus's remaining forces scatter or surrender. Porus himself is wounded and captured. The Hydaspes becomes a boundary of Macedonian territorial control.
Aftermath and consolidation
Alexander grants Porus favorable terms and reinstalls him as a vassal ruler. The victory opens the route eastward but exhausts the Macedonian troops, who will soon refuse further advance.
