Elias I, called de la Flèche or de Baugency, was the Count of Maine, succeeding his cousin Hugh V, Count of Maine.

The Battle of Tinchebray took place on 28 September 1106, in Tinchebray, Normandy, between an invading force led by King Henry I of England, and the Norman army of his elder brother Robert Curthose, the Duke of Normandy. Henry's knights won a decisive victory: they captured Robert, and Henry imprisoned him in England and then in Wales until Robert's death in 1134.
