Maybe you're thinking of "Drummossie Muir" -- that being the original name of the place it was fought. That's the title of a poem by James Hogg, beginning "Were ye at Drummossie Muir", tune (and burden) "Bonny Laddie, Highland Laddie". Please supply all the details, as much as you can, otherwise finding the thing may be difficult. Any words? Where did you hear it?
