Chapter 26: Rāmacandra Destroys Dūṣaṇa and his Followers

Furious that his army had been partially destroyed, Dūṣaṇa deputed five thousand rākṣasas to deal with Rāma. Rāma destroyed them along with Dūṣaṇa’s three commanders-in-chief. Khara then sent twelve army supervisors to destroy Śrī Rāmacandra. Rāma destroyed them and their followers. Khara then personally approached Rāma.
