Total: 6,700 Total: +6,700 Captured: Killed: Henry's claim: 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.

[4] After quickly taking the fortified abbey of Saint-Pierre-sur-Dives (near Falaise), Henry turned south and besieged Tinchebray Castle, on a hill above the town.

Those captured included Robert, Edgar Ætheling (uncle of Henry's wife), and William, Count of Mortain.

[11] Robert de Bellême, commanding the Duke's rear guard, led the retreat, saving himself from capture or death.

[13] Robert Curthose had a legitimate son, William Clito (1102–1128), whose claims to the duchy of Normandy led to several rebellions which continued through the rest of Henry's reign.
