In 1862, Abraham Lincoln politely rejected an offer by the King of Siam for a contribution of War Elephants. During the Civil War, Vice President Hannibal Hamlin was an advocate for arming Black Americans. He also starting in 1860 was a member of the Maine State Guard. He proceeded to get called up in the summer of 1864 and opted to serve despite his being allowed not to take part (being Vice-President and all). The only perk he wasn't able to refuse (he wanted to be treated like any citizen-soldier) was being quartered with the officers. He would proceed to rise to the rank of Corporal. So here's a what if: Have Hannibal Hamlin and his African-American Legion cross the Appalachians with their War Elephants.
