infantry digging in... that is a big fail.
Biggest dig-in fail I ever saw: I think it was Tara/CE, several years ago. They had their army deployed in an archer opening, with Archers in front, and infantry on middle. The
entire army was dug in. When we attacked, our infantry charge rushed in while their infantry sat back one line, all snug and safe behind their improvised fortifications, watching us slaughter their archers. Then, of course, we moved on in to obliterate the rest of their army. Despite both armies having pretty much equivalent forces, we emerged from the battle with almost no losses.
I'm not sure I still have that battle report. I think the hard drive it was on has succumbed to failure...
