Sallying out when under siege + fighting a field battle

[Monarch]

In campaign I heard when you're besieged you can sally out and fight a field battle outside city walls. How do you do this?

When I select all units in city, and atack the siegers I just end up in city walls, ai with no siege equipment, and us sitting there. I then have to drag units out of city walls and redeploy.

That's how it's intended as far as I can tell. You're doing it right.

I noticed though that when the AI sallies, I do have my equipment.
When I sally out, the equipment the AI has built is not on the battlefield.
Where do they hide that siege towers?

That's the point of sallying out, to attack the siegers before they can build lots of siege equipment.

Just don't lose a sallying battle, because I'm pretty sure that if you do, you lose the city as well.

Absolutey, its a huge advantage if you can catch the enemy army before they bring in ladders etc. I was able to defend Antioch from the Monguls five times with zero casualties because I sallyed forth before they were able to get siege equipment.

Er, but couldn't you do that in Rome?

I thought that this was a new feature, where you fight a field battle outside city walls, as in you can deploy outside city walls.

Obviously I'm mistaken, apolgies

If you attack the seiging army with a relief army then you can fight a field battle and your units inside the castle will arrive as reinforcements. Otherwise no you cant deploy outside the walls when you sally forth.
