They took anti-air weapon to a siege of air force base of operations? What madness is this?
Also, there usually a reason why those huge cannons are mounted on naval vessels and exist on land in singular digits or as static defences. I mean, I'm not an engineer, but you'd think boyancy would be required to keep the thing mobile...
@HOOfan_1 Not really. Personal relationships played big role in medieval squabbles, especially in internal conflicts like that one. It sounds wierd for modern person sinse we strayed from feodalism a lot, but in such setting everything pretty much fits.
