Cincinnati was the favorite horse of General Ulysses S. Grant & was given to him as a gift. He was the son of Lexington, the fastest 4-mile thoroughbred in the United States. Cincinnati nearly equaled the speed of his half-brother, Kentucky, & Grant was offered $10,000 in gold or its equivalent for him, but refused. He was 17H, & in the estimation of Grant was the finest horse that he had ever seen. Grant rarely permitted anyone to mount the horse --2 exceptions were Admiral Daniel Ammen & Abraham Lincoln.
Grant rode Cincinnati throughout the rest of the war and to negotiate Robert E. Lee's surrender at Appomattox. Cincinnati stayed with Grant at the White House after Grant became president. Almost all paintings or statues of Grant show him on Cincinnati.
