dvandva-yuddhaṁ su-tumulamubhayor vijigīṣatoḥāyudhāśma-drumair dorbhiḥkravyārthe śyenayor iva

The two fought furiously in single combat, each determined to win. Contending against each other with various weapons and then with stones, tree trunks and finally their bare arms, they struggled like two hawks battling over a piece of flesh.
