I've had an "Oh, Sh*t!" moment before(forgive me, it wasn't in M2:TW)

I was playing the ERE in the BI expansion for R:TW and I was following a Strategy guide tip; get every Comitatense and Eastern Archer unit in one army and ship them offf to an enemy stronghold and I decided to crush the Goths....bad move.

When I sent my army into battle, I decided not to take any chances and Played it out. I was doing really good at first; My archers flaming everything he sent at me, it all went to hell whe I moved in my Infantry.....

I had about 12-14 Comitatense units including 2 Mercenary ones. They all marched up the streets of the wall-less city and confronted the enemy, and my archers literally provided Covering "Fire", as in Flaming arrows. At the same time, my Cavalry(1 general and 1 Scholae Palatinae) charged up another road to flank the enemy, and my general got killed in the charge!

After that, I saw a bunch of Purple banners flashing white and the enemies practically ran over probably 1,000-1,500 soldiers in just a few seconds,() and that's when I said "Oh, Sh*t!!!!!"
