Surrounded DC - Supply Question - Quasi Siege

[JohnnyReb]

So I was able to surround DC completely with my forces yet it seemed I could not "bleed" the 30k combat power garrison stack dry of general supply. I saw the combat power drop to 22k and the green bar drop to nothing, but then the next turn it would bounce back up both in combat power as well as the green bar. I did not have any units in the DC area performing a siege, it was more of a "surrounding" siege from all the neighboring territories. So my question is, should this tactic work in bleeding the enemy's effective power down to zero which would force that person Athena to attack me? Then I realized, that if I was in that situation as the north, I would simply buy massive amounts of Supply Wagons in DC each turn in order to prevent what I was doing from happening to me.....thoughts? I would think that with this strategy, DC's troops would shrink down to the sustainable level that the city can support with general supply. I.e. if only 50 troops can eat, and you have 200,000 troops, eventually you will kill off all until you get to the 50 mark. Of course the supply wagons totally change this approach up....

If i'm not mistaken, as long as the surrounding regions are not 100% MC by you, then there is a chance some supply will get through.
I think you need at least 25% MC for supply to get through.
Supplies also can come in via the sea or river, and the cities produce some supply too.
Look at the wiki for more info on supply

DC has a port. It'll get supplied by the sea for as long as the Union has transports in the shipping box.

The game stores a lot of GS in certain cities (I believe Washington DC might be one of those). So it may take a while. Do you have ships in the Potomac River right outside of Washington as well? If not, then supplies could flow into the region from the sea (through the harbor). Also there is a supply test thread, where the consensus is that supplies can cross over rivers that are blockaded. So you may have to capture every region within 5 spaces of Washington (including river regions) to block supply.

Washington Harbor does not belong to the Seaways because its Exit-Point is not Coastal Waters. So Washington does not get Naval Supply.

Stationing =>4 war ships/gunboats in the Washington Harbor Exit-Point--Potomac River--will block supplies from moving through the Potomac River region, but will only prevent supplies from crossing the Potomac River using the Jump-Link with a 90% probability--23% probability per combat element, but not >90%, the same as blocking a land stack from crossing a river region--per supply distribution phase, of which there are 3 per turn.

Blockading--see the tool-tip of the harbor's Exit-Point region--the harbor's Exit-Point affects production, but not supply transportation, other than as described in the previous paragraph.

You must have >25% MC in a region for your supplies to move into or through that region.

Any friendly, unopposed combat unit in a region will prevent enemy supplies from entering that region. If a combat unit is opposed, the 25% rule still remains in affect.

Remember, Washington DC generally has very high production, which you can only reduce by besieging and blockading the harbor.

I'd swear that DC still received Naval Supply, for some reason. huh *shrug*
I'll take your word on it, that it doesn't.

I was curious though, so I opened the structures view up to take a look. DC generates a lot of supply! Holy cow![ATTACH]31893[/ATTACH]
By my count, I see: 36+9+25+10+16+2=98 (!!!) supply every turn.
That's enough to feed a few armies, all on it's own. wow!

Oh, um... Orso?...

Washington Harbor does not belong to the Seaways because its Exit-Point is not Coastal Waters. So Washington does not get Naval Supply.

Its exit point is Coastal waters, so it receives Naval suplly. But that can be blocked if you hold Alexandria fort.
As for the issue of taking too long for them to spend accumulated suplly, it's another issue discussed in the too much GS thread

JK!

I stand corrected! Haven't looked into that in ages, but I thought the last navigable part was only mamby-pamby river

So to prevent Naval Supply from reaching Washington DC you must Blockade the Potomac River. Base value is 8 combat elements to blockade; subtract 4 from that if you can also bombard into the river and have a stack set to do that. See here: 9.1.3 Blocking Riverine and Naval Supply
