The Battle of the Basque Roads, also Battle of Aix Roads (French: Bataille de l'île d'Aix, also Affaire des brûlots, rarely Bataille de la rade des Basques) was a naval battle during the Napoleonic Wars off the Island of Aix. On the night of 11 April 1809 Captain Lord Cochrane led a British fireship attack against a powerful squadron of French ships anchored in the Basque Roads. In the attack all but two of the French ships were driven ashore. The subsequent engagement lasted three days but failed to destroy the entire French fleet.
