How to Run Large Battle Scenes (Army vs. Army) - Need Advice!
So we're coming up to the climax of my story, which is an assault on the capitol city of the realm by a massive army (think the Battle of Pelennor Fields, when Mordor was assaulting Minas Tirith in Lord of the Rings, or Helm's Deep).
There's two elements to this part of the story.
- The individual encounters of the party, as they defend the city. One encounter is them defending the gate, another few are them making sorties into the battle-field, another is taking out the battle-ram, etc. These are pretty straight-forward "normal" encounters (which happen to include an endless stream of minions) where the individual characters have a task to do among a massive battle, but is focused on their little area. I don't need much help on this (though suggestions are welcome), it's the next bullet I need advice on...
- The other element is how to manage the overall battle, and the armies fighting each other... this is what I need help with.
How do I manage the overall battle?
Some of the characters are in a position to command portions of the army, and I want them to be included in how the forces move, how the army as a whole defends, etc. But I have no clue what system to use to manage combat of an army of thousands against another army of thousands.
