I got this info frm other forum not sure if it is correct-
Prithvi's friends from gurukul die yet the war rages on... Finally, Bhidev's men are overpowered. Prithvi's warriors make a wall of bodies at the opening of the pass. Bhimdev's men see the pile and run for their lives. As night descends, Prithvi and his friends rest for the night to resume war in the morning but the first rays of the sun get a bigger shock for them as they are surrounded by Bhimdev's men and the one to lead them... None other than the loyalist turned traitor Vibhishan. Vanraaj asks Prithvi to lay down his arms before of the king of Gujarat. Prithvi actally lays down his arms, bows before the king and starts taking off his armour as Bhimdev sneers and suddenly out of the blue... Prithvi, swift as the wind picks up a spear and sends it swishing through the air, right into Bhimdevs heart! He falls dead. Prithvi's forces spring into action and all hell break lose as Prithvi and his men fight like men possessed n vanquish vanraaj n his forces ..the benevolent prithvi satisfied aftr avenging his fathers defeat does not kill bhimdevs son vanaaj instead he puts him on the throne of Gujarat n leaves ..his greatness touches vanraaj too.
