He had defeated so many kings in the middle east the western Asia and reached the North-western India. In the northern India he had to fight with Puru, a great king and a brave soldier. Puru was a noble patriot. He did not like India to be conquered by any foreign ruler. So he decided to fight against Alexander. There was a great battle, between Alexander and Puru on the banks of Jhelum. His soldiers, generals fought bravely. Puru also fought like a tiger. He killed hundreds of Greek soldiers and injured many with his sword. Puru lost the battle though his generals and soldiers fought bravely. Puru lost the battle as he had used the oldest methods of warfare and he used elephants. Puru was gravely injured and chained in the battle. He was brought before Alexander. Alexander liked his bravery and courage. He did not like such a great king to be in captivity., He asked his soldiers to remove his chains. Alexander asked Puru to be his vassal. But Puru refused. Alexander asked him why he rejected his offer.- Puru said that he was the lawful owner of his kingdom. He asked Puru how he should treat him. Puru asked to treat him as his equal. Alexander liked his bravery, gave back his kingdom. Alexander liked Puru’s self-respect, so became his best friend.
