The author (O’Brian) wrote something like 12 books in this series.
My husband gobbled them all up - said they were wonderful. He was also a big Horatio Hornblower fan when young.
I believe the series was twenty novels, twenty-one if you count a final unfinished book that was published as-is.
They were great reads, I think I’ve read the entire cycle 6 or 7 times so far.
O’Brian is a descendant of the Commodore Anson who took the Manilla treasure galleon “Covadonga” in 1740, after sailing around Cape Horn. One of four the British took in three and a half centuries. Hi
Anson was later First Sea Lord and O’Brian was born in the manor house Anson built with his share of the treasure.
