Congratulations Darrell, these are really well done. I particularly like the rocks as well. On the blog you say you used Milliput, was this to join bark pieces together or just to bed them onto the base. I tried some of these a while ago but they came out nowhere near as nice as yours.
When we first released Principles of War (20 years ago!) we did Maiwand as a demo game at various shows. A very interesting battle.
