Non-PRO English to French Art/Literary Poetry & Literature expression

This is from "Might is Right" of Ragnar Redbeard.

... She(Majestic Nature) loves the writhing of sword-blades, the rending of tradition, the crunching of bones, and the flap of shredded shot-torn banners, streaming out savagely(in the night, in the day), over the battle-weary, the mangled dying and the swollen dead.

Thanks in advance.
