The enemy's central army has collapsed.
Following Duncan's charge, the Huns' vassal army began to fall apart on a large scale. The real main battle infantry was gradually slaughtered, and the remaining prairie slave army and prairie vassal army were just there to make up the numbers, collapsing easily.
However, unlike Duncan's past defeats of other enemies, the collapse of the vassal army did not affect the main forces of the Hun cavalry.
The Huns have always used vassal armies as cannon fodder.
