That would be a good idea. It would be best to plan this as a defensive battle and plan to use our shock cavalry sparingly, largely using them to outmaneuver massed infantry. Particularly while engaged with our own infantry, they are too precious a commodity to waste sallying forth early (Unless we can cause a rout). In the early days we should largely focus on digging in and preparing for a siege. Our own archers and siege equipment will be of no use to us if they are countered in larger numbers by the offensive army. We should be building earthen works and creating shields to prolong the lives of our soldiers. Especially if we expose our archers by placing them high, we will want them to have some kind of shielding preferably something semi portable.
Pitch particularly fired from a catapult or the like would be a brilliant idea in the confined spaces of the canyon and is fantastic way to break morale of the offensive army. Especially when combined with caltrops to limit speed and maneuverability.
If we can use some of Pizarks Hunters and trappers to find some goat paths leading through the mountains we will need to divert a small amount of men to protect them but it may also open up the ability to sabotage supply lines.
But really there can be no concrete plan or clear way to deploy our forces until we know the disposition of the enemy.
It is also important to remember we are not trying to kill as many as possible (Although more is better). We are trying to delay them.
All great points, especially about morale and our ultimate purpose here. We should try and figure out some creative ways in which we can wear down the enemy's morale, maybe something like nighttime raids to keep their watchmen on edge, psychological tactics like chucking the decaying bodies of their dead back at them, creepy magic voodoo shit, etc. I don't think Alaric will necessarily underestimate us (being the tactician that he is, he'll recognize that we have a strong position), but he'll know that he obviously has the upper hand. So it's a question of how much we're willing to sacrifice, how deep we're willing to go, to prove our mettle and see who blinks first.
As you said, I think that on the first day we should be as defensive as possible, sounding out the enemy, digging ourselves in, and not wasting our precious few troops on any aggressive maneuvers.
@babbysama I am all down for digging trenches, making traps and building defenses. If you need some tinkering done or something built, you can come to my guys.
I was thinking of creating these little catwalks in the side of the pass, perhaps by digging them out, or reinforcing existing ledges. Could be a nice place to snipe them from.
My other main idea is something like siege towers used as mobile defensive emplacements for archers. Multiple levels with windows that you could shoot from. Plus maybe even heated oil to pour at the people below.
All good ideas, though I wonder how the siege towers will work once we've entered the final phase and are effectively under siege by the enemy's forces. It also might unduly expose our missile troops, and unless they're properly defended, they could be breached easily by infantry. I'm still down for the idea but we'd have to divert resources to their defense at the expense of other fronts. Just something to keep in mind while drawing up our plans. But catwalks on the side of the pass, sounds dope.
