'High Germany', with that 'Cursed be those cruel wars' line would be good if you're not confining yourself to Child. It's in the DT here but NB the first line should be corrected to "Oh Polly love..." - "Colleen" is plain wrong. For a good-soaked naval ballad try 'Polly on the Shore', but treat the version in the DT with caution as again it's inaccurate and credited to Randy Newman (!!??).
