Cannons and castles, at first glance, seem to be incapable of existing together in medieval warfare. Surely a wall is no match for a cannon? But when did cannons come about, and what were the first cannons like? Who was able to afford cannons? All will be answered in this video which looks at cannons, castles, and the forts that we see in the 1800s because I got a little bit carried away. Again.

If you think I've got something incorrect, please leave a (pleasant) comment about it down below, I'll check it out. If you do so, make sure to use some sort of reliable source, in oppose to a generic website/YouTube video/Wikipedia. If I conclude that I was wrong, I'll pin a comment about it, or just pin your comment.
