I saw the vision of armies;
And I saw, as in           dreams, hundreds of battle-flags;
Borne through the smoke of the battles, and pierced with missiles, I saw
them,
And carried hither and yon through the smoke, and torn and bloody;
And at last but a few shreds of the flags left on the staffs, (and all in
silence,)
And the staffs all splintered and broken.
