As soon as the news of his brother's defeat reaches him in Longka, Sahatsadecha remusters his army and, swearing a terrible vengeance on the monkeys, marches it swiftly to the battlefield.

Pipeck, the wise demon, has told Phra Ram that this is exactly what the King of Pangtan will do.  He warns Ram that Sahatsadecha is the possessor of a terrible club that kills whoever it is pointed against and advises the royal leader that Hanuman be sent to see what he can do to counter the threat of this weapon.

To undertake the mission, the Son of the Wind changes himself into a small white monkey, and leaves the camp to intercept Sahatsadecha.  He has little time to wait.  The demon has come up posthaste and after the outriders of his army have passed, Hanuman springs out of the undergrowth where he has been hiding directly into the path of the royal chariot.  At this unexpected occurrence the lions pulling the chariot buck and shy and twist their traces, bringing the chariot, and indeed the whole army, to a halt.  By this time Hanuman has leapt into a nearby tree, and the furious Sahatsadecha orders his soldiers to drag him down and put him to death.

"Don't kill me, great one," Hanuman whines, cringing and pretending to be terrified.  "I've sought you out especially to put myself at your service.  My one thought is the same as yours, to kill Phra Ram."  And the ingenious monkey goes on to explain that he had been a citizen of Keetkin under Palee, but was made a slave when Phra Ram killed Palee and appointed Sukreep king in his place.  From then on, he says, life has been unendurable for him, and he has escaped with the intention of killing Ram.  He pleads with Sahatsadecha to be allowed to take part in the coming battle against the royal brothers.

The demon is rather taken with the idea of having a monkey in his service and permits Hanuman to sit on the shafts of his chariot.  Then he orders his army to march on.

Well satisfied with this turn of affairs, Hanuman waits until the battlefield has been reached before making his next move.  Then, when the two armies are confronting each other, he turns to Sahatsadecha, and trembling realistically, begs to be allowed to sit at the rear of the chariot, with the concubines.

"Pah, you monkeys are all cowards," says Sahatsadecha.  But he is too preoccupied with the ordering of his forces to think of the danger of allowing a potential enemy to sit behind him, and says, "Go, do just as you wish."

Hanuman takes his position at the rear of the chariot.  He casts an expert eye over the pleasure girls there, no situation is too urgent to inhibit thoughts of dalliance, and then, even as the demon army is breaking into the charge, mutters a spell to himself.  He is immediately transformed into a giant monkey with four faces and eight arms, and so great is his weight that the chariot breaks to pieces beneath him, throwing Sahatsadecha and his concubines to the ground.  Quick as a flash Hanuman seizes the demon's magic club.  Even as the enraged Sahatsadecha is bellowing at his soldiers to kill the monkey, Hanuman points its deadly end at them, mowing them down like grass under the sickle.  Having done so he breaks the club in two.
