Things you just never do in battles.

Never ever think "This is my time - why with one glorious charge, my already exhausted troops will chase the enemy entirely from the field, and thus their hordes of still available reinforcements will also waver and flee."

They won't, and your guys are now too tired to even run away.....carnage ensues, accompanied only by the sobs of a virtual general, and the gentle thudding as said general's head pounds the desk next to his/her keyboard.........
