FERSEN, Count Axel, Swedish soldier, born in Stockholm in 1755; died there, 20 June 1810. He was the son of Count Axel, field marshal of the army of Sweden, was educated at the military academy of Turin, ltaly, and soon afterward catered the Swedish army. After brief service he was appointed colonel of the royal regiment of Swedes, the bodyguard of Louis XVI., king of France. Count Fersen came to the United States as a member of the staff of Rochambeau, fought under Lafayette at Yorktown, and retired with the French army, after receiving from Washington the order of the Society of the Cincinnati. At the time of the treason of Benedict Arnold he wrote interesting letters to his father in Europe, which have been published, describing agreeably men and manners in the days of the Revolution. Oh his return to France, Count Fersen became a devoted adherent of the royal family, and in their flight from Paris was the disguised coachman of the fugitives. On their capture, Fersen escaped, and returned to Sweden, where he was made chancellor of Upsala University, became a court favorite, although he was unpopular with the people, and was promoted grand marshal of the kingdom. The sudden death of the crown prince gave rise to the suspicion that Fersen had poisoned him, which is now acknowledged to be unfounded. At the funeral, Fersen was attacked by a mob with sticks and stones and killed, while the troops looked on with apparent indifference.
