Har har.. Scupper the swabs...
If you can't breach the stronghold,use a good old tried and tested bio-weapon solution..
Catapult dead,decaying,disease ridden animals over the fortress walls..
Or if dead animals are on the shortage list,I've got a pair of old Y-fronts that'll do the same job...
(hmmmm...actually it's time to turn them inside out and get another 5 months wear out of them..
