I just watched a show "How it works" or something on how they cast Cannon.....
Help....
Cast iron?.. ok, I can work with that.
Reaming out the inside with a lathe?....
Fine, that I can handle.
Lining the hole with Epoxy Resin and then pushing in a steel Liner?.......
PHWATT?.....
These are supposed to be "Period" cannon replica's?....
Did the real ones have steel lining?.. I dont think so.
Did they stick the linings in with Epoxy Resin?....
You havin' a giraffe aint ya?...
I dont think they even had linings back then did they?...

Anti-Personale cannon, I can hold with that.
I suppose the first breach the castle plan would have involved taking out the doors?...
And no, I DONT mean a after-show party for an American rock band either...
I mean blowing the doors off....
BEHAVE!....
I now have a vision of Michael Cain "Your only supposed to blow the bloody doors off..."
Pointing the cannon at the walls I suppose would have come later with bigger heavier cannon.

It would depend I think, Castle Gate houses where often defensive strong points, with multiple towers covering angles of attack, killing zone within barbicans etc, blowing a hole in a wall might work better if you chose an area that had less obvious defences.
It was probably a matter of evolution over time, were defences around castle gates in place before guns, due to over forms of siege weapons or did they come into existence afterwards? I guess the best way to check would be to,look at something like the Crusader castles abandoned before cannon came into use, I will have to,look at that when I get time.

This depends on period powder.
I have strong suspicions that the first powder was not strong enough top blow the brains of a Monkey out through his nose....
I suspect as powder was refined, they could do more damage, and as cannon got better, and they got better barrels, better seal between powder and shot, they became more dangerous over time.
Again the analogy of Us having Laser....
In the beginning, it wouldnt cut paper.
Now you can do Steel....
How much better will they get?.
What will people in the next century say of our weapons tech today?....

Yes, gunpowder became more and more powerful over time.
That said more powerful powder didn't automatically mean more powerful. More often it just mean that you could get the same amount of power using less powder.
The main limitation was the strength of the gun, and using new powders in older guns, even those that were in good condition, was usually a great way to blow the gun up. You can often tell when newer, stronger, powders were introduced (even when it isn't noted well elsewhere) from the way governments had to run around replacing older guns in fortifications that had blown up when they used the newer powder.

actually, gunpowder was already pretty well refined by the time the europeans got ahold of it and thought, "hey this would be great for killing people with" - the chinese had been practicing the fine art of making pretty explosions for quite a while, already.

The idea of better and better is along the analogy of Internal Combustion going from one cylinder to four, to six, to eight, from 500 cc to 1,000, to one two three four five six seven eight litres and above, fuel octane ratings change that, then you get "Top fuel" and dragster engines.
Evolution.
Look at the original Ford T, then look at a Shelby Cobra.
You get the idea it has evolved a little?....
Look at the original small wagons....
Now look at the latest road-train 1,000 hp+ tow your house down trucks.
The Canon was the latest technology of the time, it evolved in use, powder got better, barrels got better, they went for better range, and bigger power.

We used to have thousands of Battery Powered Milk Floats, vehicles designed to move quietly in the early hours of the morning with fresh milk deliveries around towns. It s said at on stand most BEVs in the world where Milk floats.

but we are drifting away from the question of whether a rubble filled wall could absorb impact from siege weaponry better than a wall built full thickness.

since we're putting options in the pot, I think that can be added. I'm a bit confused about the exact design, there, though. the official website is no help in seeing the design. can you find a good link for the overall layout? the best thing abut Fort George is it is a gunpowder era fort, so design elements could be compared to older fortifications, if they wished to address whether cannon were superior to older siege engines. |

yes, I think I got the historic scotland site. the visitscotland site does give a basic layout which makes it more clear what I am looking at in your picture. |
