As a Scipii, I lost a full stack -- not very experienced but made up of a goodly mix of Hastati/Princs/Archers two Generals and 3-4 cav units.
12 Mac Lancers charged frontally in a broad line and crushed the entire force, then mowed down the routers as 1 Scip unit after another briefly regained discipline just long enough to keep the slaughter going.
Another time, I had a full stack of Brutes attacking a smaller force of Greek phalangites in the Peleponese. While winning solidly, I ran out of time. My troops and general evaporated leaving nothing and delaying the attack of Greece for a decade.
