Well, historically keeping your men from pursuing fleeing foes was one of the hardest task and I fear that unless the XXth century no commander ever manage to succeed at that efficiently.

So I will rule out the no pursue order, basically.

Some example of commander having suffered thus move ( expecially from his cavalry ) : Caesar, Scipio, Alexander, Darius, François Ier, Napoleon, Wellington,... and many more ( basically every middleage commander ).
