Defeating the Greeks

War Against the Yavanas

With the Mauryan dynasty overthrown and Greeks advancing on Pataliputra, Pushyamitra faced his first test as ruler. The Indo-Greek kings commanded battle-hardened armies with superior cavalry and siege technology. Could a Brahmin general succeed where Mauryan emperors had failed? The battles that followed would determine whether India remained Indian, or became a Hellenistic province.

The Test of Fire

Pushyamitra Shunga had seized power claiming that the Mauryas could not defend the realm. Now he had to prove he could do what they could not. The Yavanas (Greeks) were advancing toward the Gangetic heartland, and they had no intention of stopping at the old frontiers.

The Enemy

Indo-Greek phalanx advancing on the Gangetic plain

The Indo-Greek forces represented the finest military tradition of the ancient world, the heritage of Alexander's Macedonians, refined through a century of Central Asian warfare. Their army combined:

Greek Infantry:

Disciplined phalanx formations
Sarissa (long pike) tactics
Shield wall coordination developed over centuries

Bactrian Cavalry:

Heavy cataphracts (armored horsemen)
Central Asian horse-archer traditions
Mobility and shock tactics

Siege Capability:

Greek engineering expertise
Siege towers and battering rams
Experience reducing fortified cities

The commander, Demetrius I of Bactria, styled himself "Aniketos", the Invincible. He had already conquered Gandhara and the Punjab. His generals, including Apollodotus and Menander (who would later become famous in Indian tradition as Milinda), were experienced campaigners.

Pushyamitra's Army

Pushyamitra's forces were the remnants of the once-mighty Mauryan military machine. The army had declined under generations of neglect, but it retained important advantages:

War Elephants:

India's traditional armored fighting platforms
Terrifying to horses unfamiliar with them
Effective against infantry formations

Numerical Strength:

The Gangetic heartland could raise large armies
Motivated by defense of homeland and dharma
Fighting on familiar terrain

Home Advantage:

Knowledge of local geography
Secure supply lines
Fortified cities as strong points

Most importantly, Pushyamitra brought something the later Mauryas had lacked: determined leadership. A commander willing to fight and die with his men.

The Campaign

The Greek invasion followed the traditional route through the northwestern passes, then down through the Punjab toward the Gangetic plain. The sources are fragmentary, but we can reconstruct the general course of events:
