Add more votes to Bogle's pair (No Man's Land and The Band Played Waltzing Matilda). And the Prines that have been mentioned as well. I never saw Draft Dodger Rag as an anti-war song. It's from Ochs's superpatriot stage and I've never been convinced he had his tongue in his cheek. I think he really was poking at draft dodgers (love to be wrong of course). Fixin' To Die Rag is pretty good too.
