Which of these names was not the name of one of Napoleon Bonaparte's horses?

Blueskin is the name of a horse that was not one of Napoleon Bonaparte's names for a horse. Blueskin was the name of the horse ridden by George Washington. He was one of Washington's primary mounts during the American Revolutionary War. The horse was half-Arabian, sired by the stallion "Ranger", also known as "Lindsay's Arabian", said to have been obtained from the Sultan of Morocco.

Blueskin was a dashing stallion “of a dark iron-gray color, approaching to blue”. He was called a spirited animal, known for his endurance. He was a gift to Washington from Colonel Benjamin Tasker Dulany (c. 1752–1816) of Maryland. Due to his white hair coat, Blueskin is the horse most often portrayed in artwork depicting Washington on a horse.

Marengo (c. 1793–1831) was the famous war horse of Napoleon of France. Named after the Battle of Marengo, through which he carried his rider safely, Marengo was imported to France from Egypt following the Battle of Abukir in 1799 as a six-year-old. The grey Arabian was probably bred at the famous El Naseri Stud.

Wagram, a gray Arab, was another famous horse of Napoleon Bonaparte. Napoleon rode this animal from 1809–1821. He was with Napoleon during his time in exile in Elba.

Napoleon during his life also used a horse named Intendant. It was a pure white Anglo-Norman horse, nicknamed "Coco" by the Imperial Guard. Historically, he was used for parades and reviews because of his calm nature during such ceremonies.
