A poem by Walt Whitman, from his Leaves of Grass, from the "drum taps" section, which were written during the American civil war.

World take good notice, silver stars fading,
Milky hue ript, weft of white detaching,
Coals thirty-eight, baleful and burning,
Scarlet, significant, hands off warning,
Now and henceforth flaunt from these shores.
