Ajatashatru. The chariot moved about in the battlefield crushing lakhs of soldiers. This war-chariot was named Ratha-Musala. In this battle, Chetaka was defeated. But, Chetaka and others immediately took shelter inside the city walls of Vaishali and closed the main gate. The walls around Vaishali were so strong that Ajatashatru was unable to break through them. Many days passed, Ajatashatru became furious and again prayed to Indra, but this time Indra refused to help him. But Ajatashatru was informed by an oracle of a demi-goddess "Vaishali can be conquered if Sramana (monk) Kulvalaka gets married to a courtesan." Ajatashatru inquired about the monk Kulvalaka and sent for the prostitute Magadhika disguised as a devout follower. The fallen woman attracted the monk towards herself and finally, the monk gave up his monkhood and married her.

Kulvalaka gave a signal and Ajatashatru proceeded as per prior arrangement. This was the last attack. Vaishali was conquered by Ajatashatru.

However, because of sheer lethargy, Ajatashatru failed to collect his own share, and most of diamonds were carried away by the Lichhavis. Over time, finally, Ajatashatru became annoyed and decided to do something about it. Since he thought that it might be almost impossible to fight against the whole confederacy of Vaishali, he decided instead to uproot the powerful Vajjis and exterminate them. He sent his chief minister Vassakara to the Buddha to ask him why the Vaishali should be so invincible; to which Buddha gave seven reasons, including: That the Vajjis are always punctual to meetings,
