Erwin Muilwijk:
You're welcome. You'll find a lot of good, generally unpublished information in the book. While Howie only takes his chapter through 1814, what he describes as 'battle array' SOPs and conventions holds true for Waterloo. For instance, both the French and the Allied formed their brigades and divisions with the guide/honor position towards the center of the battle line, which indicates quite a bit about each sides' plans of battle.
For instance, Pack's brigade had the 28th on the left, the 79th in the center and the 32nd on the right [If I remember the correct numbers], which is one of the configurations Howie expains the why and hows of in the long chapter.
Best Regards,
Bill
