All books by Bernard Cornwell. Particularly the Richard sharpe series. 18 books, Napoleonic war, it follows the life of a gutter born son of a ***** British private as he rises through the ranks. Avid reader here and these are probably my favorite military fiction of all time. Very very good

its basically the land version of “master and commander” series by Patrick obrian. If you haven’t read that series then giddy up for about a years worth of awesome military fiction
