Administrative / biographical background
In 1808 Gambier was appointed to command the Channel Fleet. In April 1809 he chased a squadron of French ships that had escaped from Brest into the Basque Roads. He called a council of war in which Lord Cochrane was given command of the inshore squadron, and who subsequently led the attack. Gambier refused to commit the Channel Fleet after Cochrane's attack, using explosion vessels that encouraged the French squadron to warp further into the shallows of the estuary. This action resulted in the majority of the French fleet running aground at Rochefort. Gambier was content with the blockading role played by the offshore squadron. Admiral Sir Eliab Harvey, who had commanded "Fighting Temeraire" at the Battle of Trafalgar, believed they had missed an opportunity to inflict further damage upon the French fleet. Cochrane threatened to use his parliamentary vote against Gambier in retaliation for not committing the fleet to action. Gambier called for a court martial to examine his conduct. The court martial, on 26 July 1809 on Gladiator in Portsmouth, exonerated Gambier.
