@Sardonac - When can you hit siege towers with onagers? I've tried it with my onagers behind stone walls, but whenever I click to attack the siege tower, the onagers do nothing at all, they sit there. However, if I tell them to attack the units after they come out of the tower, then they'll fire at the units (not the siege tower though).

(this is speculative - comments welcome!!)

I've had the situation where the seige tower is within range but when told to fire at the seige tower, the onager just sits there.

I suspect that the problem may be that the prog checks to see if the unit being fired at is in range, then looks to see if the onager can hit the unit. If the stone wall gets in the way, it can't hit it so it doesn't fire.

With big stone walls, assuming basic physics, then the onager should be the same distance away from the wall as the target is on the other side for the onager to have the best chance of clearing the wall (ie the max height of the shot will be mid-way between onager and target, and you'll need max elevation of shot to clear the wall.)

Often the best way to hit a seige tower that is near to the wall is to aim at a unit further away but in line with the tower.

(Not true of low walls where the onager can shoot over them quitee asily.)

class dismissed.

Once a unit starts climbing the tower then there should be no problem targeting it.

Another option - put the onager unit on "fire at will" and move it towards your settlement wall - it may well hit upon a sweet spot from which to hit towers before they get to the walls.

I was fighting up on the walltops (I was attacking a stone-walled settlement). I planned this out in advance, so it worked quite well. I sent a unit of town watch on the walls were they're best units were. Of course, my townwatch were getting surrounded and killed. Then I ordered my onagers to attack the section of wall were the siege tower was that had dropped of my town watch. The wall collapsed, killing my town watch (which are useless), but completly destroying the two good units that were attacking it. Good trick!

On a campaign game I accidentally allowed the city of Alexandria to rebel and it resulted in the Egyptians gaining a full stack of level 8 and 9 units with gold armour and weapons.

I trained an army that consisted of half legionary units (4 Praetorian Cohort, 3 units each of Legionary Cohort and Early Legionary Cohort) and half assorted ballista/scorpion/repeating ballista units. The ballista units did not kill very many troops and it was only after my infantry had engaged and killed many of them that they routed. Even then I only won the battle with approximately 30 Praetorian Cohort men left and most of the ballista units.

And I only fought half of their gold level army.
