PseRamesses: Sorry. I misunderstood the reference to 'routing troops returning'...I thought that meant coming back after their visit to the Plaza.

If faced in the open field with a bigger enemy I recommend sending a cavalry unit to the enemy flanks. Even one weak unit will help pin the enemy army. Use local superioity in numbers against any units you can pry away from the enemy. All the time refuse battle if odds are not in your favour. Run the clock down if you can.

Tiberius: 4 archer units in that army. Not high but one of the largest concentrations I had. That was near the end of the campaign. My play style is micromanage and pause a lot. So easy enough to control. Tactics are usually the same. Gain control over the battlefield with cavalry, pour fire on any good targets, retreat before enemy infantry until all missiles gone or numerical advantage obtained. I kill few troops in hand to hand except with cavalry.
