cutting off trade routes

[MattPilot]

I'm sure one of you civ geeks out there knows this

I think i read once that you could put the harbor out of service when you put one of your own ships right next to an enemy town (during war time of course). And if memory serves me correctly, i think i did this in pre conquests games.

Though now in my latest epic game, i'm trying to cut off a city with a harbor on a remote island which coincidentally has the only rubber source for that civ (i checked, it didn't get the rubber from another civ cause its at war with everyone, and no - there is no airport). For this task i've allocated my only destroyer in the region. Though the coastal city has 4 sea squares. Doing some espionage missions, i can see that the main land still has access to that resource - even after a turn.

Conclusions:

a) it no longer works (or never has worked) to cut off harbors

or,

b) you need to cover every single coastal square to cut it off.


does anybody know what the deal is with this?


Also, Can i cut off an airtrade route by placing AA units adjacent to the city? Currently don't have the resources in my game to test this.

Any input greatly appreciated!

you need to blockade it completely, such that the enemy would not be able to move a ship in or out of that port. sounds like you'd need 3 more destroyers to do the job.

oki kewl - you got any idea about the AIrport & AA question?

trade route blocking is all but useless, especially late game.

if there were defined paths merchant ships traveled, that could be blockaded, destroyed, or raided, it would be a lot better.

surrounding an entire city (or GROUP of cities) is retarded.

I don't think you can cut of air routes, you have to destroy the airport.

I've cut off every water path out of a city and it could still build units it didn't have the resources for, leading me to believe the blockade wasn't working.

[MattPilot]

just did it.. and it worked. Blocking all 4 squares of the previously mentioned town eliminated the resource from the main land. Thanks for the help!

I just wish there were a way block Air trade routes with AA units - hope Jesse changes that

Did they have an airport? Did they have roads to anothe city that had a harbor? I know they can use other civs trade routes on some circimstances, but I am not sure how that works.

I had supply resources on a continent from my home continent but when I got in a war that source of resources was cut off.

What Happened? I had many ports to ship the ore.

Did you have a trade with someone for the resource? If say you have 2 sources of Iron and trade one and lose the road to one of them or it depletes, the trade will be filled with your remaining resource.

That would mean you would have none for your interal use.
So that is one way. Of course if you only had one source in the first place and it was depleted, then you are SOL.

Check with F2 to see if you have that resource still and check your trades.

IIRC navigation allows trade over sea, and magnetism allows trade over ocean.

if you don't have either, you can only trade across coastal tiles. if you go to war with someone IN THE PATH of your current trade path (like, if they control the coasts you would use to get there), you can't trade.

[Alexander's Horse]

I have lots of sources and modern ships.

[vmxa1]

Can you post a save where this occurred? Best if it is just before you lost the access.

[Alexander's Horse]

I will when I get home - it looks like the enemy civ has somehow blocked trade routes to my home continent - but no ships are evident and I have dozens of open ports on both continents.

Nope and nope and the only other cities it had roads to were mine.
