    It is widely known that any unit can defend a capital against barbarians and win if the capital is the civ's only city. I do not, however, remember coming across the fact that a capital gives a 2 times defence bonus against barbarians under normal circumstances. Yet this seems to be the case, as I found by this test:

    Test Parameters
    Large Map
    7 Civs
    Raging Hordes
    Simplified Combat
    Other Rules Standard
    Start Techs: Bronze Working

    Vet Warriors, Not fortified, in Capital
    Vet Barb Archers attack.
    20 Archers attack a city defended with 20 warriors (city size 25). Vets and simplified combat ensure that all 20 combats are uniform.

    “Standard” expectations:
    Barb attack: 3(1.5)(1.5)=6.75 Barb Deity bonus and Vet bonus
    Warrior Defence: 1(1.5)(1.5)=2.25 City defence bonus and Vet bonus
    Barbs win 75% of the time.

    Actual Combat Results: Only Capital
    Test Warrior Archer
    Round Wins Wins
    1 20 0
    2 20 0
    3 20 0
    4 20 0
    5 20 0
    Total 100 0

    Combat Results: Capital plus one city.

    Non Capital city plus capital
    1 6 14
    2 6 14
    3 5 15
    4 5 15
    5 6 14
    Total 28 72


    A capital does seem to give a bonus against barbarians, while non capital falls in closely with expectations. In order for the barbs to win 60% of the time, the approximate result, the warrior must defend at 4.5 or the Barb must attack at 5.4. Thus, the warrior must either have a 2x defence bonus or the archer must have a .8x penalty. An increased warrior defence of 2x seems much more plausible and within normal bonus multipliers, as opposed to a 20%penalty to an attacker.

    The attatched files are the base for the tests I did. BARBTEST tested the barbs attacking the capital while BTEST2 tested barbs attacking a regular city. To test for additional cities with the capital, create extra settlers and build cities with them in the BARBTEST file.

    is it the palace that does this?

    would be interesting to try and rig a test to discover that.

    So I guess that when I get a message that says "X civilization destroyed by barbarians", it means that the barbarians had previously attacked and captured the capitol when X civ had one or more other cities, and then the barbarians captured the remaining city or cities before another capitol was established.

    Or, that the capitol of X civ did not have any units to protect it...

    Possibly, or that the computer doesn't receive a total defence against barbarians if they only have one city.
