Yuddha Kanda is the second last chapter of the epic itihasa, Ramayana. It begins with Sugriva commanding Nala and Nila to commence building a bridge popularly known as Ram-Setu between Bharata and Lanka. Before the rama army starts their travel to Lanka, shri rama decides to pray to his chosen deity, Lord Shiva and honors him by constructing a Shivalinga which is one of the 12 Jyotirlingas, Rameshwaram. Shri Rama's army reaches Lanka and takes camp at Mount Suvela where they prepare for the upcoming war.

Ravana is informed of Shri Rama's arrival and decides to play a few tricks with Maa Sita. Queen Mandodari, the wife of Ravana and his son, Prahasta tries to convince Ravana to return Maa Sita to lord rama but Ravana denies it. Vibhishana also requests Ravana to return Maa Sita to Lord Rama and tell Ravana about Shri Rama being a Vishnu Incarnation, Ravana again denies it and throws Vibhishana out of his Kingdom. Vibhishana then seeks refuge under Shri Rama and he accepts him as a valuable aid to him.

Thereafter, the war begins with Ravana sending his commanders one by one with them being killed by Hanuman, Sugreva, and Angad. On the third day, Ravana commands his servants to wake Kumbakarna from his sleep to aid him in the War. Upon disturbing his sleep, Kumbakarna gets angry at Ravana for doing such an unholy deed and again requests him to return Maa Sita. Ravana again ignores it and commands him to go to war. Kumbakarna participates in the war, and kills many but inevitably gets killed by Lord Rama's arrows.

On the fourth day of the War, Laxmana is injured badly by an arrow shot by Indrajit, Ravana's eldest Son. Thereafter, Lord Rama consults Vaidhya, Sushena who informs them of Mrit-Sanjeevani in the Himalayas and asks them to bring them before Sunrise. Shri Rama gives this responsibility to Lord Hanuman who travels almost 8000 Km in one night to bring these herbs. Lord Laxmana is saved by those herbs and vows to kill Indrajit. Vibhishana then informs them of a Yagnya which is being performed by Indrajit, to his deity Nikumbhila. If this yagnya is successful, Indrajit could never be defeated by anyone, so, Visbhishana asks Laxmana to destroy it. He takes them to the place and a war between Laxmana and Indrajit takes place with Indrajit getting killed in the End. Ravana is petrified at the sight of all his commanders and sons being dead and decides to participate in the war. Ravana enters the battlefield on the 5th and final day with all glory and might.

Shri Rama and Ravana fight mercilessly on the battlefield when Lord Rama chops Ravana's head off. Being a demon having no control over his senses, a new head emerges and Ravana fights again. Lord Rama is shocked at this sight and learns about a boon that was given to Ravana by Lord Brahma from Vibhishana. Then Vibhishana guides Lord Rama and requests him to shoot an arrow in Ravana Navel where an Amrit Kalash [Pot of Nectar] is housed and asks to destroy it. Lord Rama acts on the advice given by Vibhishana and shoots an arrow straight at Ravana Navel, ultimately killing him.

With this, the epic war comes to an end and then Lord Rama requests Vibhishana to perform ceremonial rites for Ravana. He then makes Vibhishana king of Lanka and as king, his first command is to Free Maa Sita. Maa Sita is reunited with Lord Rama after giving Agni Pareksha and Vibhishana gifts them Ravana's Pushpak Vimana to go back to Ayodhya.
