Oh, I've read all of the Sharpe series too! They are also excellent. I have not looked into the other authors but I've added them to my book list.
Another great series, but with a humorous ribald twist are the Flashman books by George MacDonald Fraser. Fraser takes Flashman, a nasty character in the book Tom Brown's School Days, and inserts him into real stories from the 1800's English history. He is a coward, a cheat, and a cad, but very charming & handsome and he always comes up smelling like a rose. They are written as Flashman's memoirs, and my Dad (he recommended these books also) told me that when the first book was published back in the early '60s some reviewers thought it was non-fiction.
