He had already conquered most of the subcontinent. The Maurya Empire under Ashoka stretched from Afghanistan to Bangladesh, from the Himalayas to the Deccan. He was not fighting out of weakness or desperation. He was fighting because Kalinga — the only major kingdom not yet part of his empire — had refused to submit.
He won. Decisively. One hundred thousand killed. One hundred and fifty thousand deported. Many more died in the aftermath from displacement, famine, disease. The numbers are from his own edicts — he was the one who counted and recorded them.
He rode through the field after the battle and looked at what his victory had produced.
What happened in him on that field is recorded in his own words, inscribed on rock faces and polished stone pillars across the empire — the Rock Edicts, the most remarkable self-examination ever conducted by a military conqueror in the ancient world.
He wrote: when an independent country is conquered, the slaughter, death and deportation of the people is extremely grievous and weighs heavily on my mind. This is considered even more deplorable by the Beloved of the Gods. I am filled with remorse.
He converted to Buddhism. He sent his own son and daughter as missionaries to Sri Lanka. He built hospitals for humans and animals. He planted trees along the roads. He dug wells. He declared animal sacrifice at the royal court abolished. He issued edicts about religious tolerance — perhaps the first in human history. He said explicitly that other sects should be honoured, because by honouring others you honour your own.
The most powerful king of his age, after his greatest military victory, chose the path that made him most powerful in a different way — not through force but through the quality of governance and the quality of the self that governed. The Buddhist concept he embraced — Dhamma, the right order of things, the way of living that reduces suffering — became the operating principle of an empire. Not perfectly implemented, not without contradictions, but genuinely attempted. He is considered the model of what a ruler can be when the ruler has looked honestly at what power costs. The edicts do not hide the remorse. They inscribe it in stone. I am filled with remorse — carved into rock, set at crossroads, placed where travellers would read it for generations. The greatest conqueror of his age wanted to be remembered for the battle he did not fight after Kalinga.
Ashoka's pillars are still standing. The Ashoka Chakra — the wheel of Dhamma from one of his pillars — is at the centre of the Indian national flag. The lion capital from his pillar at Sarnath is the national emblem of India. He is not remembered for Kalinga. He is remembered for what Kalinga produced in him.
Some victories teach the winner more than any defeat could. Kalinga was won and won and won again in the years that followed — not by armies but by the hospitals, the trees, the wells, the edicts of tolerance that the man who saw the aftermath of the field insisted on placing everywhere he could reach.
What has your greatest victory cost? And is the cost visible enough to produce what Kalinga produced in Ashoka — the honest remorse that changes the direction of everything that follows?
