I guess we were posting at same time eh R'as?

It comes down to fact that map edges should not exist, orders should be obeyed however it is not the case so we have to intervene. By selecting engage at will the HA are freed of their skirmish action and now will obey commands.

Using this principle I was able to defeat armies 3 times larger than mine and I had only 700 HA, some 4 units of Nobles the rest Scythian HA. It is like hit and run, attack and retreat. When enemy targets some of your units, turn others on to them, all the while pulling enemy out of formation. If you have some units like Sarmatian mercenaries in reserve, isolated units can be easily despatched
