After her soldier husband's accidental death, she enlisted in the Confederate States Army in 1861.  She then fought at Bull Run, Ball's Bluff, and Fort Donelson, but was discharged when her gender was discovered while in New Orleans.  Undeterred, she reenlisted and fought at Shiloh, until unmasked once more.

The poem refers to the confinement between 1945 and 1958 of Ezra Pound in St Elizabeths Hospital, Washington, D.C.  The nursery rhyme style gives an unusual effect to the strange or unsettling descriptions of a psychiatric hospital in the poem.  Likewise the poem treats Pound ambivalently describing him by turns as "honored", "brave", "cruel", and "wretched" among other things.
