The Battle of Hydaspes, fought in 326 BC, stands as a significant event in the annals of world history. This defining battle was a confrontation between Alexander the Great and King Porus, also known as Paurava. The result was a decisive victory for Alexander and his Macedonian army, which had profound implications for the Indian subcontinent, exposing it to Ancient Greek political and social influences.

In this article, we delve into the details of the Battle of Hydaspes, which was fought on the banks of the modern-day Jhelum river, in the context of the Civil Services Examination.

Alongside the Battle of Hydaspes, there were many other important battles in Indian history. Here are some of them for further reading:

The Prelude to the Battle of Hydaspes

The story of the Battle of Hydaspes begins after Alexander the Great's successful campaign against the last forces of the Achaemenid Empire in 328 BC. With his sights set on further expansion, Alexander turned his attention towards India in 327 BC. Leaving a contingent of 10,000 men to fortify Bactria (modern-day Afghanistan), he embarked on an invasion of India via the Khyber Pass.

Despite having an army that heavily outnumbered the enemy, the battle proved to be one of the most challenging in Alexander's career. His forces sustained significant losses, unlike in previous battles.

The Greek column forged ahead through the Khyber Pass, while a smaller force, under Alexander's command, took a northern route. They conquered the fortress of Aornos (modern-day Pir-Sar), a place of mythological importance to the Greeks, en route. According to legend, even the mighty Herakles had failed to capture it during his campaign in India.

In the early spring of 327 BC, Alexander formed an alliance with Taxiles (also known as Ambhi Kumar), the King of Taxila. Together, they prepared to face King Porus, the ruler of Hydaspes, who had refused to surrender to Alexander and was readying his forces for war.

The Battle of Hydaspes: A Detailed Account

Alexander set up his camp near the town of Jhelum, on the right banks of the river. In the spring of 326 BC, Porus positioned his forces on the south bank of the Jhelum River to resist any attempts at a crossing. The river was both deep and fast, making any crossing attempt a risky proposition.

The battle eventually commenced, with the Indian forces arrayed with cavalry on both flanks, chariots at the front, and a center comprised of infantry. Stationed every fifty feet in front of them were heavily armored war elephants, intended to deter the Macedonian cavalry. The Indian soldiers, clad in brightly colored garments and steel helmets, armed with axes, lances, and maces, presented a formidable opposition.

Alexander, recognizing the strength of Porus's center, decided to first attack the flanks with his cavalry, holding back his phalanx until the Indian cavalry had been neutralized. This strategy proved effective, despite the Macedonian infantry being outnumbered five to one by the Indian infantry.

The war elephants advanced against the Macedonian cavalry, causing heavy losses among the Macedonian foot soldiers. Despite this, the Macedonian infantry resisted bravely, with the light infantry targeting the elephants' mahouts and eyes with javelins, while the heavy infantry attempted to hamstring the elephants with their two-sided axes.

Eventually, the Macedonian infantry advanced upon the confused enemy forces, while the Macedonian cavalry charged from the rear in a classic “hammer and anvil” maneuver. This strategy resulted in the rout of the entire Paurava army.

The Aftermath of the Battle of Hydaspes

After the battle, King Porus was brought before Alexander. When asked how he wished to be treated, Porus responded, "Treat me as a king would treat another king." Impressed by his courage and dignity, Alexander allowed him to retain his lands.

However, in 326 BC, as Alexander's army neared the borders of the Nanda Empire, they grew weary from the continuous campaigning. The prospect of facing another massive Indian army further dampened their spirits. As a result, at the Hyphasis (modern Beas), the troops demanded a return to the west.

Rather than immediately turning back, Alexander ordered the army to march south along the Indus, securing its banks as the borders of his empire. This decision marked the end of Alexander's campaign in India.

During the later reign of the Maurya Empire , Chanakya, the royal advisor, used the Battle of the Hydaspes as a lesson, emphasizing the need for military training before battle. The first Mauryan emperor, Chandragupta, maintained a standing army where chariots played a lesser role in battle.

Thus, when the soldiers heard of Alexander’s plan to march further east, they refused and almost mutinied. Thus Alexander was forced to halt his Indian expedition for good.

What was the significance of the battle of Hydaspes?

The battle is historically significant because it resulted in the exposure of ancient Greek political and cultural influences to the Indian subcontinent, yielding works such as Greco-Buddhist art, which continued to have an impact for many centuries.
