Great AAR, Sheep! Can't wait for the next chapter!
About the auto win cheat, it works like this:
-press the tilde key (directly under "escape" and left of "1")
-type in auto_win
-add at the end: attacker(if you're attacking) OR defender (if you're defending). Generally you put in attacker during your turn, and defender when it's not.
-however for AMBUSHES, it's the reverse. If you're ambushed (your turn, logically), the enemy is attacking, and to win the battle the cheat is: auto_win defender
If you ambush(the AI's turn, supposedly), the enemy is defending, the cheat is: auto_win attacker.

Especially don't forget the "underline"(_).
Also, you can use it pretty much without cheating, for when navies clash (you're forced to auto calc it, which may give some rather absurd results) or when you've got a force of 10 units, and the other has 3, just use auto win, especially for EB (long loading times... GAH!)

Also, Sheep, the losses of your troops are those you would normally have when having a "clear victory" from the auto_calc (I think...)
