It's not a humiliating defeat, but...

I started a VI campaign as the Welsh and it was my very first battle of the campaign.
I had 5 units, 2 of Archers, 2 of Celts and my General had a horse unit.
I was arranging my troops in the first minutes of the battle, the enemy were not even in sight. One of my units of Celts suddenly got disturbed by the lack of flank cover while they were moving into position, and they began to route!!
What a bunch of Chickens!!
It's a shame they enemy wasn't on the other side of a hill, if they'd have seen it they may have laughed themselves to death.
