Why Royal Navy battles were not commanders acting from boredom

Was an Ottoman fleet destroyed because the Royal Navy commander was bored?

No. The government made the political decision and issued the orders; the Royal Navy did not independently start wars for entertainment.

A Royal Navy commander could not destroy an Ottoman fleet simply because he was bored. The British government first had to make the political decision that placed the fleet in a position to act. Naval officers carried out those orders rather than initiating a war and informing ministers afterward. Dramatic battles such as Navarino still sat inside civilian policy and authorization.
