The Battle fought between the Soul — Nightmare

The Battle fought between the Soul 1
And No Man-is the One
Of all the Battles prevalent-
By far the Greater One-

No News of it is had abroad-5
Its Bodiless Campaign
Establishes, and terminates-
Invisible-Unknown-

Nor History-record it-9
As Legions of a Night
The Sunrise scatters-These endure-
Enact-and terminate-
(F.629/J.594)
