Case 15a: LAGOS~BOSCAWEN~AUGUST 19

 

 

 

Naval power played a crucial role in the Seven Years’ War, and two of the celebrated British victories of 1759 were won at sea.  With much of the fighting taking place in the French and British colonies of America, sea power was essential in allowing the mother countries to sustain their efforts.  For the first three years of the conflict, the French were able to successfully project sea power, but 1759 would see the tide turn against them.

A French invasion of the British Isles was a worrisome possibility during the first years of the war.  In order to accomplish this, however, the French needed to establish naval superiority in the English Channel.  This meant concentrating a fleet scattered between the Atlantic and the Mediterranean.  Early in August 1759 an attempt to move part of the fleet from Toulon to the Atlantic met ruin near Lagos Bay on the coast of Portugal, when Admiral Edward Boscawen (1711-1761) captured or destroyed five French warships and blockaded the rest in Spanish ports.
