you often hear people say the point of castles was so that when the attacking army comes marching through and starts capturing cities and land and whatnot, that they dont want to leave castles behind them because the soliders in the castle would be able to mess with their supply lines and conduct raids on them from behind, BUT i just learned that castles only held like 30 fricking dudes. what are 30 guys gonna do if you just fricking ignore them and march on by? So i ask again, why not just ignore enemy castles? even if you ignored 3 castles, thats 90 men, and if you have an army of 15,000 they cant do fricking shit, let alone re-capture cities and lands you now hold.
Im asking this because i've been trying to do research for an upcoming session where the party is going to take part in a siege, i thought the castle would have like 6,000 duded protecting it, but here i am, learning that castles had like 10-20 jabronis
