I just finished Steven Brumwell's book Redcoats. I thought it was an outstanding book, though it dealt little with the British soldier's experience in the French and Indian War and what Brumwell referred to as the "American War". Having also read White Devil, all I can say is that I recommend both books highly. It gives a tremendous insight to the daily workings of the British army from 1750-1850, and a real feeling for what those who "took the King's shilling" lived through.
