Strategic Narrative Overview
On the night of 11 April 1809, Cochrane led a squadron of fireships and bomb vessels into the Basque Roads. Though causing little direct damage, the attack panicked the French crews and most ships grounded. Cochrane expected Admiral Gambier to follow with the main fleet to destroy the immobile French force, but Gambier refused. Cochrane continued fighting for several days with minimal support, destroying some ships before being recalled on 14 April; sporadic combat continued until 24 April.
01 / The Origins
In February 1809, the French Atlantic Fleet attempted to break out of the British blockade at Brest to reinforce Martinique. Chased by British squadrons across the Bay of Biscay, the French failed to escape and anchored in the Basque Roads near Rochefort. The British Admiralty, eager to destroy the trapped fleet, ordered the junior but celebrated Captain Lord Cochrane to lead an unconventional inshore attack over the protests of senior officers.
03 / The Outcome
Most of the French fleet refloated and retreated up the Charente to safety. Britain celebrated a partial victory, but dissatisfaction with Gambier's inaction was widespread. Cochrane used his parliamentary seat to publicly denounce Gambier, who demanded a court-martial. A jury packed with Gambier's allies exonerated the admiral. Several French captains were court-martialled for cowardice and one was executed. Cochrane's naval career effectively ended, while the French Atlantic Fleet remained crippled and confined.
