Upon seeing Paraśurāma, Kārtaviryārjuna immediately feared him and sent many elephants, chariots, horses and infantry soldiers equipped with clubs, swords, arrows,  ṛṣṭis ,  śataghnis ,  śaktis , and many similar weapons to fight against him. Kārtaviryārjuna sent seventeen full  akṣauhiṇis  of soldiers to check Paraśurāma. But Lord Paraśurāma alone killed all of them.
