I have written 2 very long pieces on this battle now. I was logged in both times and when I posted it scrapped the lot and told me I was not logged in, even though I definitely checked before. So I'll write this, post it and then go in and edit my post and no one will hopefully see this nonsense!

Even that didn't work. It accused me of a hacking attempt and logged me out again. I have written this quite long piece 3 times now and can't be bothered again.

The Special rules are quite long for this game to simulate the escalating commitment of troops (There, I said in one line what it took about 6 paragraphs to do before!). If anyone has any question over how/why it works the way it does please ask away.
