Brest is an important city and harbor in the Hornblower saga. It was a main focus of the British navy during the Napoleonic wars as much of the French fleet was here and the Navy's primary mission was to contain the French fleet and to destroy any that venture out.
Hornblower and the Widow McCool: The Channel fleet was stationed off Brest many times for just this reason. After a battle in which the French brig Espérance was taken as a prize, the fleet fled before a storm to Tor Bay during the court martial of Barry McCool, deserter. The fleet returned to Brest and the Bay of Biscay after the storm.
Hornblower and the Hotspur: Hotspur, Commander Hornblower commanding, is assigned by Admiral William Cornwallis to 'look into Brest' to determine progress of the French fleet and its state of readiness as the Peace of Amiens draws to a close, and to keep Cornwallis informed.
