I Saw Old General at Bay by Walt Whitman Lyrics

I saw old General at bay,
(Old as he was, his gray eyes yet shone out in battle like stars,)
His small force was now completely hemm'd in, in his works,
He call'd for volunteers to run the enemy's lines, a desperate emergency,
I saw a hundred and more step forth from the ranks, but two or three
         were selected,
I saw them receive their orders aside, they listen'd with care, the
         adjutant was very grave,
I saw them depart with cheerfulness, freely risking their lives.
