The Battle of Tinchebray (alternative spellings: Tinchebrai or Tenchebrai) took place on 28 September 1106, in Tinchebray (today in the Orne département of France), 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 (in Devizes Castle) and then in Wales until Robert's death (in Cardiff Castle) in 1134.
