What a blast, loved it.
I took the German's and charged in as far as I could, but once the armoured cars came there was little I could do. I thought on until the very end, although a bout an hour before the finish I knew I couldn't win as I'd lost too many troops and wouldn't have been able to get eight off the board.
One quick question...
The cavalry enter the board either trotting or charging, but for the armoured cars it only says enter, does that mean then they only enter on that turn but don't move until the following turn?

And here's my own turn track design
