Ulysses S. Grant (born Hiram Ulysses Grant; April 27, 1822 – July 23, 1885) was the 18th President of the United States (1869–1877) as well as military commander during the Civil War and post-war Reconstruction periods. Under Grant's command, the Union Army defeated the Confederate military and ended the Confederate States of America.
He was seen in "Peter, Peter, Caviar Eater" as a patron of the Cherrywood whorehouse.
In "E. Peterbus Unum", Peter tells of his ancestor Ulysses S. Griffin, as being a great leader of the Union Army. Ulysses Griffin is then seen winning against the Confederate General Robert E. Lee in a drinking contest.
Peter declares victory over hijackers in "Passenger Fatty-Seven" as quicker than the treaty signing at Appomattox, leading to Lee agreeing to surrender but allowing the South to continue to be dicks forever.
