Yuddhakānda - Canto 42

Approaching Rāvana, the ogres break to him the news about Lankā having been laid siege to by the monkeys led by Śrī Rāma. Ascending the roof of his palace and taxing his brain about the means of putting an end to the monkeys, he casts a look at Śrī Rāma and the monkeys. Pained at the thought that Sītā was being bullied by Rāvana on his account, and commanding the monkeys to besiege all the four gates of Lankā and to destroy the ogres, Śrī Rāma, on the other side, takes up his position alongwith Laksmana near the northern gate. Apprised of these developments, Rāvana mobilizes his army and, encouraged by him, the ogres beat their drums and emit a terrible roar.
