Thanks to O'Brian, the standard for this kind of historical fiction is so high that comments are necessarily comparative and are therefore likely to sound more negative than they really should. That said, the writing, dialogue, and character development are simple. The situations and event development appear somewhat artificial at times. I could wish the British establishment not appear to be so uniformly monstrous. These books are pleasant, but could be enjoyed and probably fully understood by a 12-year-old.
Nelson certainly knows his history, his ships, and particularly the working of those ships - the detail is pleasing and authoritative. This, added to the American setting, makes the trilogy quite recommendable.
At time of writing, I've not yet finished the 2nd book, which is better than the 1st; things may improve yet.
