In Mr. Midshipman Hornblower: The Duchess and the Devil, at the dinner at Governor's House in Gibraltar, as the guests were served Malaga, the comment that 'Old Hare bought a job lot in '95, 'Old Hare' likely refers to General Charles O'Hara who was Governor from 1795 to 1802. However, this dinner would have occurred during his tenure, but, the conversation seems to indicate a number of Governors since O'Hara.
