The last win of Flatman's career came on the Tuesday of the first October meeting of 1859. He won a match on Golden Rule for Admiral Rous. The following Thursday, he was riding again for Rous on a horse called Golden Pippin. The filly started at odds of 6/4 but was unruly and ended up beaten three-quarters of a length. It was to be the last ride of his career. On the way back to the weighing room, the mare kicked Flatman, breaking a rib. The story, however, appears differently from different sources. Some have the horse owned by the Duke of Bedford, not Rous.
