Calculating Defense Values

[SuperSaxon771]

In a game I was playing the other day, I set up a city at an ithsmus (sp?) in order to block an enemy's expansion. I was trying to calculate the defense strength of that city, but then I realized that I'm not exactly sure how the defense values are calculated in Civ I. Here is what I was thinking....

The best defense unit in the city was a musketeer. Defense Value = 3

The musketeer was a veteran, so that's + 50%; 3 x 1.5 = 4.5

The veteran musketeer was fortified, so that's +50%; 4.5 x 1.5 = 6.75

The city was protected by city walls, so that's +200%; 6.75 x 3 = 20.25

The city was located on a mountain, so that's + 200%; 20.25 x 3 = 60.75


Is this correct? It seems to me that a Defense Strength of 60.75 is WAY too high. If it's not correct, then how does the game calculate Defense Strength? How would I do it in this situation?

That could very well be correct!

From the civ1 guide:
6) The Canal trick
This is an excellent idea received from Matt Malone.

a) Build a city on an isthmus. Enter ships from one side, leave from the other. Instant canal. Similarly a chain of cities for longer canals. Also good for access to inland seas.

b) Build a walled city on a mountain as the gateway from an inland sea to the ocean (veteran. riflemen defense = 5*1.5*3*3 > 63). It provides a bay that is impervious to enemy ships and several city sites that are "coastal" - i.e., able to build ships - while not being subject to sea attacks until the gateway city falls.

c) Land a settler and build a city between an enemy city that is not coastal and the ocean to create a canal to allow a battleship to pound the enemy city directly. If your canal city is walled the effective defense with a veteran battleship is 12*1.5*3 = 54! Good odds in any attack except against bombers

Great answer Zwelgje Couldn't have quoted it better myself

Heh, I read that guide years ago and remembered somewhere in it there was this calculation. I just had to dig it up.
