Among the sources of confusion Stephens saw, close at home, was the Southern battle over the reopening of the slave trade. The reality of that issue had been made plain in May, 1859, when the Southern commercial congress at Vicksburg entertained at the same time two resolutions: one, that the convention should urge all Southern States to amend their constitutions by a clause prohibiting the increase of African slavery; the other, that the convention urge all the Legislatures of Southern States to present memorials to Congress asking the repeal of the law against African slave trade. Of these opposed resolutions, the latter was adopted on the last day of the convention*, though the moderates fought hard against it.

*It is significant that the composition of these Southern commercial congresses and the Congress of the whole Southern people was strikingly different in personnel. Very few members of the commercial congresses reappear in the Confederate Congress.


The split between Southern moderates and Southern radicals was further indicated by their differing attitudes toward the adventurers from the United States in Central America. The Vicksburg Convention adopted resolutions which were thinly veiled endorsements of southward expansion. In the early autumn another Nicaraguan expedition was nipped in the bud by the vigilance of American naval forces. Cobb, prime factor in the group of Southern moderates as well as Secretary of the Treasury, wrote to Buchanan expressing his satisfaction at the event, mentioning the work of his own department in bringing it about, and also alluding to his arrangments to prevent slave trading off the Florida coast.
