The Battle of Valmaseda (or Balmaseda) took place on 5 November 1808, during Lieutenant-General Blake's retreat from superior French armies in northern Spain. Reinforced by veteran regular infantry from General La Romana's Division of the North (Spanish: Division del Norte), Blake's force suddenly turned on its pursuers and ambushed Marshal Victor's errant vanguard under Général de division Villatte.
