Historically, I thought that the romans built a fort every night when in enemy territory. I suppose the EB equivalent would be building every turn...
I seem to remember something about a lazy general on campaign thinking that he could do without, as it was getting dark, he was tired etc etc. Anyway, the army was attacked and suffered large losses, and the general had strips torn off him when he got back to Rome.
I'll see if I can find where I read that...
