You did some really good work here. I liked the historical background and that you gave disclosure about what isn't historically accurate. Nice to have different kinds of maps too in-game. I would have liked to see a more visible confirmation of when I clicked soldiers, they were very small and it was hard to choose them all and make them move. Maybe you could fuse them all together so that 5 soldiers make up a unit or something and you move all 5 when clicking one of them? Just an idea. :)
Well done overall!
