what width/depth should a good moat have?
Learn the difference between personal and private property
Showyou dug a moat to protect your "property" from the proletariat, i dug a moat to protect my home from my landlord. we are not the same
a good moat should be 3 spans of an oxen and too deep for an ox to ford. but your castellan should probably know this. are you looking for one?
must be wider then a horse can jump , otherwise the Tatars will get you
Understandable and I did not take it in bad faith, no worries. Besides, aren't we all liberals anyways?
Everyone's a liberal except me. I'm the only real leftist.
That depends, are we talking about a dry moat or a water castle moat?
For any moat, the total height from the top of the wall to the bottom of the most should be enough that the enemy cannot use a ladder to climb over the wall. This was easier to achieve before you could walk into a hardware store and come back with a 40' ladder.
The most itself must be deep enough that your attackers cannot simply walk across it if it is a water moat, and any moat should have difficult terrain at the bottom, concrete tetrapods are great. Just make sure the highest point of the terrain is still deeper than a person could stand in.
The width of the moat should be at least 1:1 with the height of the walls above the waterline, and the wall should extend smoothly from the top to the bottom of the moat, with nothing that could be used as a hand or foot hold.
Let me guess: you became a communist within the last year or so and have recently discovered "toothbrush jokes" all the while, right?
