Marengo was a grey stallion ridden by Napoleon of France. The stud was only 14.1 hands, but was an incredible war horse. He was wounded eight times, in different battles. In the Battle of Waterloo, Marengo was captured and sold to Lieutenant-Colonel Angerstein in the UK.
At 27 years old, the stallion stood at stud. No known offspring exist, however. The horse lived to 38 years old.
If you visit the Royal United Services Institute, you are able to view Marengo's skeleton, which was preserved and has made it's way to the museum for display. The display is the complete skeleton, missing only the horse's hooves. The location of two of the hooves is unknown, however the other two were saved and given to private parties. Both of the privately owned hooves have been loaned to various museums for display.
