Question on Blocking Land Movement Across Rivers

[Johnny Canuck]

I have a quick question regsarding how one uses naval units to block enemy land movements across a river. Can a single naval unit prevent enemy land units from crossing a river, or do I need to have a number of naval units equal to the number indicated for blockading the harbour? For example, as the CSA I've moved up to the Ohio River, and I want to use some gunboats to prevent Union forces from crossing the Ohio to attack south. Is one gunboat per river zone enough, or do I need to match the blockade number? Thanks.

A single unit is enough

Blockade numbers are for brown-water blockade of production/income (or suchlike); not sure what the blockade number means for rivers, but for blocking supply and land unit movement, a single unit is sufficient.

Thanks for the info, Rafiki. I just took Louisville, but see that Grant is on the north side of the Ohio, & would very much like to keep him there.

I wonder if river transports can block river crossings. Or must it be a combat ship?

combat ship

I seal the whole Mississippi off one gunboat at a time. Makes one feel safe as the USA aggressor.

Interesting. So can anybody explain what the blockade number means for rivers?

BTW, English is not my mother language and I don't understand what you mean for "brown-water" (rivers delta?).

'Brown water' refers to coastal waters and rivers. 'Blue water' refers to the deep ocean.

Same as they mean for ports on the ocean...if you blockade all the zones adjacent to a port, the city suffers economic consequences.

Brown water means coastal or inland waterways. Blue water refers to out on the open ocean.

the tooltip list you the number needed for every coastal region, but is not intelligent enough to check if you have a nearby harbor so that the number has a real meaning.
