In Blockade the civil war in America is in full swing and James spots the chance to make a fortune running a unionist blockade to the embattled South.
The blockade is also affecting Britain too, valuable import/export trade is drying up closing down mills and leaving thousands hungry.
James, thanks to a wily pilot he hires at an exorbitant price, manages to make it through the blockade but hits trouble on the way back out when the pilot refuses to help them until things have calmed down somewhat. Stubborn James decides to take a chance anyway and gets captured.
Meanwhile Albert, now that he knows the truth about his child, has made up his mind to leave Elizabeth and travels with James to America only to change his mind when Anne gives him a letter from Elizabeth that makes him realise what he is giving up.
The ubiquitous Michael Sheard pops up as a wholesaler selling arms and goods to James to take to America, he looks almost unrecognisable with his lank black hair and straggly beard but the voice gives it away.
