Chanakya himself was planing to overthrow the Nanda Dynasty due to some personal insult and was creating a gurilla military. He did not want to deal with Alexander on one side and Nanda Dynasty on the other.

Alexander's men who were about 6,000 finally refuse to go ahead and fight an army that was 200,000. They had already defeated a 20,000 strong army of Porus and it was a tough one. Alexander is said to have lost his horse (Bucephalus) in the battle, now lay burried in Peshawar, Pakistan. Alexander is said to have charged Porus on his horse and Porus knocked him down... possibly unconscious... for he was carried away by his bodyguard.
