How significant was Danish/Swedish/Russian trade with the thirteen colonies, anyhow?
Almost nonexistant.
Legally all trade with the colonies had to travel on british ships, colonial ones usually counted as british. Then, any exports to the continent had to be transshipped at a british port.
Was there smuggling? Of course there was. But it mostly involved colonial ships trading in the caribbean, an i suspect french and spanish ships slipping into colonial coastal ports.
But the colonials had the right to be in the caribbean, so it was easy to sneak over to a ,,wrong,, island. And the french and spanish had lots of ships around.
!,,honest, gov, we was blown off course, and had to put in here for repairs!,,
Danish and swedish ships didnt have any excuse to be there and not only is the problem even worse for russia, but she has almost nothing to trade. Foodstuffs, furs, timber, raw materials .. both russia and the colonies produced those.
