'The Civil War, the War Between the States, was a singing war. Among the scores of marching songs, sung by soldiers, blue and grey, was this rebel satire on the rationing of chickpeas to the starving Southern troops.'

It's the footnote on page 52 of 'The Penguin Book of American Folk Songs' compiled and edited with notes by Alan Lomax.
