They went to the blue lines gladly, and the blue lines took them in,
And the men who saw their muskets' fire thought not of their dusky skin.
The gray lines rose and melted beneath their scathing showers,
And they said, "'T is true, they have force to do, these old slave boys of ours."
Ah, Wagner saw their glory, and Pillow knew their blood,
That poured on a nation's altar, a sacrificial flood.
Port Hudson heard their war-cry that smote its smoke-filled air,
And the old free fires of their savage sires again were kindled there.
They laid them down where the rivers the greening valleys gem.
And the song of the thund'rous cannon was their sole requiem,
