Ramayana has part(s) Yuddhakanda
Yuddha Kanda
Also known as Lanka Kanda, this book describes the war between the army of Rama and the army of Ravana. Having received Hanuman's report on Sita, Rama and Lakshmana proceed with their allies towards the shore of the southern sea. There they are joined by Ravana's renegade brother Vibhishana. The apes named Nala and Nila construct a floating bridge (known as Rama Setu) across the sea, using stones that floated on water because they had Rama's name written on them. An alternate story also tells that they had been cursed by a sage that whatever they will throw in a water body will not sink, rather it will float.
The princes and their army cross over to Lanka. A lengthy war ensues. During a battle, Ravana's son Indrajit hurls a powerful weapon at Lakshmana, who is badly wounded. So Hanuman assumes a gigantic form and flies from Lanka to the Himalayas. Upon reaching Mount Sanjeevani, Hanuman was unable to identify the herb that could cure Lakshmana and so decided to bring the entire mountain back to Lanka. Eventually, the war ends when Rama kills Ravana. Rama then installs Vibhishana on the throne of Lanka.
On meeting Sita, Rama said, "the dishonour meted out to him and the wrong done to her by Ravana have been wiped off, by his victory over the enemy with the assistance of Hanuman, Sugreeva and Vibhishana". However, upon criticism from people in his kingdom, Rama disowns her and asks her to seek shelter elsewhere. Sita requests Lakshmana to prepare a pile of fire for her to enter. When Lakshmana prepares a pyre, Sita prays to the god Agni and enters into it, in order to prove her conjugal fidelity. Agni appears in person from the burning pyre, carrying Sita in his arms and restores her to Rama, testifying to her purity. Rama later joyfully accepts her. The episode of Agni Pariksha varies in the versions of Ramayana by Valmiki and Tulsidas. In Tulsidas's Ramacharitamanas, Sita was under the protection of Agni (see Maya Sita) so it was necessary to bring her out before reuniting with Rama.
