Claim: Ulysses S. Grant fought against Robert E. Lee.
Evidence: As Commanding General -LRB- 1864 -- 69 -RRB- , Grant worked closely with President Abraham Lincoln to lead the Union Army to victory over the Confederacy in the American Civil War.
The Union finally won the war when General Robert E. Lee surrendered to General Ulysses S. Grant at the battle of Appomattox , which triggered a series of surrenders by Confederate generals throughout the southern states.
