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.
[1] Further mistakes were made in the French pursuit, namely when Victor carelessly allowed his Army Corps to spread out in its search for an enemy he regarded as beaten.
General Acevedo: Asturian Division [Conges de Tineo, Salas, Siero, Villivicioa, Lena, Oviedo, Castropol] (ten battalions).
On 8 November a resurgent Victor recaptured Valmaseda, killing and wounding 150 and capturing 600 men from Blake's rearguard.
[5] Upon learning of the battle, Napoleon, shocked that his Grande Armée should suffer even a minor defeat by "an army of bandits led by monks," severely reprimanded Victor for his imprudence.
