Translation: 
Thereafter, Paraśurāma cut off like a mountain peak the head of Kārtavīryārjuna, who had already lost his arms. When Kārtavīryārjuna’s ten thousand sons saw their father killed, they all fled in fear. Then Paraśurāma, having killed the enemy, released the kāmadhenu, which had undergone great suffering, and brought it back with its calf to his residence, where he gave it to his father, Jamadagni.
