The goddesses mounting excellent war-elephants for battle after knowing the effort of the Daityas. The confused melee of the elephant-mounted goddesses and Dānavas. Śumbha and Niśumbha coming to the assembly grounds with a fourfold army upon seeing their forces crushed in battle by the goddesses. The battle of Śumbha and Niśumbha with the goddess; the tumultuous clash; the Daitya armies reduced to a small remnant by the goddess. The destruction of the banners, armor, horses, and charioteers of Śumbha and Niśumbha by the goddess. The goddess seizing by their necks and crushing Śumbha and Niśumbha as they flew into the sky; the slaying of Śumbha and Niśumbha.
