How did they murder one another and protect themselves?
Bows and Arrows? Slingshots? Knives? Lances? Rocks?
Imagine surving all those CENTURIES without home armories loaded with everything from a beebee gun to an AK 47? I know you can't. Too awful to contemplate! Whom would you be without ever present loaded gun to protect yourself and also take out anyone you think goes against the demented duck? Too horrible to think about isn't it? Worry not. Y'all will have all of the guns you ever wanted in all your born days. Million of them in every size with bullets galore and more and more and more and more.
The first cannons showed up in Italy in 1320.
How many cannons do YOU own?
