Wow. Didn't know they were used as early as the War of the Roses. I knew that when Henry VIII really got into them they were still in their prime. They must have been a very basic model then. I wonder how reliable the gun was? Well, as the article said it did blow up due to the cold. But then, wouldn't you expect that? I wonder how accurate it was as well? Did it make a great impact in the War of the Roses? Or was it rarely used after that battle? Many questions that we may never know.
