Question: Supposing I had a way to partially cripple their army from inside (specifically a large fiery detonation within their barracks), how large would my forces really need to be to take Altearx? 
Knowing me, if I tried to write it out on my own, I would probably make an absolute orange farm of it all, and I don't really want to go through the strife of beating myself over the head with my mistake, then have to go back and make a hella lot of edits.
