Could someone briefly outline what the number of spires on a city means?

Could someone also briefly explain what the different fort icons mean?

Each spire can hold 5 factors inside the city. E.G. 4 spires means 20 factors can fit inside. A city is considered "fully garrisoned" when it holds within 5 of the maximum garrsionable factors (i.e. said 4 spire city would be fully garsioned with 15 or more factors, undergarrsioned with 14 or less). An undergarrsioned city gives an assauting force a +1 to breach the walls.

Each fort "fleche" indicates that an assaulting force gets -1 on its die roll to breach the walls. 3 "fleches" means -3 to assault, so a fully garrisoned 3 fleche fort (like girbraltar) is impregnable, and must be starved until it is undergarrisoned before an assault has any possiblity of success.

The no. of spires * 5 = the city troop capacity. 

The no. of fort icons = the fortification value, used in calculating assault attempts.

EDIT: Soapy Frog beat me to it, with a mnore complete explanation.

Many thanks,

How long, roughly, does it take to starve out a unit in a fort? A turn or two? A year?

I imagine starving out Gibralter would require a naval blockade? I'm assuming the Brits can supply Gibralter by sea indefinitely with the strong navy they have.

Garrisons use the number of spires as the supply value with a +1 to die roll if 5 factors or +2 if 10 or more, so to use the Gibraltar example they could hold out forever as long as they roll 1s.

Also Gibraltar can be sea supplied, so as long as British dominate the seas it can never be taken.

To take one of the worst cases in the game, a fully-garrisoned Constantinople --

Constantinople has five spires, for a capacity of 25 factors and a besieged-supply value of 5. It's a port, so it needs to be blockaded to eliminate the possibility of sea supply if there's another Turkish port with a depot in a supply chain or that's itself a supply source, and a fleet in one of the two.

As long as there are 10 or more factors remaining, the roll is at +2 -- so a roll of 4, 5, or 6 will eliminate 1, 2, or 3 factors. The other half the die, the garrison doesn't lose anybody. Once they're down to 9 factors, the roll is only at +1, so there are no starvation losses on 1-4, 1 factor on 5, and 2 on 6.

I just ran a quickie Monte Carlo simulation with 100,000 trials assuming a full garrison. The -minimum- observed starvation time was 16 months; the maximum, 132 months. The median, mean and mode were all quite close -- 46 months, 48 months and 48 months, respectively.

This ignores breaches, of course -- and even an unsuccessful storming battle where the attacker breaks will help attrit the defenders, provided the besieging force is substantial.

A Monte Carlo simulation?

My God, you're one dedicated dude.

Thanks for the info, though.
