No I am not going crazy in the mental sense, just having my understanding of something changed. I was wondering through the library as graduate students are want to do. I discovered a new section that had all the military history stuff. I began pulling books down off the shelf looking for stuff on fifteenth century artillery. I was hoping to find something vaguely useful for my thesis and perhaps later for a dissertation.
Boy was I right. I pulled down a book and was just doing a quick peruse when I saw a detailed picture of a cannon. The part of the book I was 15th century so I thought, ‘oh cool.’ I am examine this picture and I notice, it is breech-loading. The had a complicated system where you could essentially remove the end of the gun and load it the put it back and fire. It involved a wooden carriage and blocks for securing the ‘breech’ but it was a breech-loading cannon in the 1470’s.
Hence the crazy. True it would have some problems, maintaining thrust being one of them. I have to wonder how well did it actually work in comparison to its contemporaries.
