I can't remember the name of the battle, but a game version of it would go like this.
You fire idly across your trench at the enemy about 30 yards away, this has been going on for several weeks. A while passes and artillery begins to batter the enemy trenches, 6 days later the artillery clears, and now is your chance to take the enemy trench and make it all worth the hell so far!
But wait, what's this? Your commander is telling you to WALK through no-mans land or you'll be shot (As it's improper to run), suddenly the enemies machine guns are back on as you watch yourself get ripped to shreds along with all your nearby allies.
Credits roll saying 150,000 people or so died in that attack, the war dragged on for a few more years and your death was a pointless waste caused by incompetent command. You're also told that the enemy (A respectable sovereign nation much like your own) suffers so massively from their surrender terms that the war indirectly leads to the rise of the most evil power of modern times. Fighting this evil power also happens to destroy your own nations glorious empires rule, and paves the way for the previously isolationist crazies to replace you.
It doesn't quite have the punch of 'Kicking the evil nazi's ass! Fuck yeah!' WW2 had.
