हरिराक्षसदेहेभ्यः from the body of Rakshasas and Vanaras, प्रभूताः come out, केशशाद्वलाः in the form of hair, शरीरसङ्घाटवहाः the dead bodies like logs of wood, शोणितापगाः streams of blood, प्रसुस्रुः flown.

M N Dutt

Elephants and cars were like the banks of that river of blood, the arrows were like the fishes, and the flags were the trees on their banks and the corpses were like planks afloat there.

Summary

In that war, the streams of blood that flowed from the bodies of Vanaras and Rakshasas were strewn like weeds in the form of hair, bearing logs of wood in the form of dead bodies.
