The Battle of Tinchebray (alternate spellings Tinchebrai or Tenchebrai) was fought 28 September 1106, in the town of Tinchebray (in today's Orne département of France), Normandy, between an invading force led by King Henry I of England, and his older brother Robert Curthose, the Duke of Normandy. Henry's knights won a decisive victory, capturing Robert and imprisoning him in England (in Devizes Castle) and then Wales until Robert's death (in Cardiff Castle).
