So instead he started a war which killed it. It just took four years for the body to hit the floor.
They made the mistake of believing what Lincoln said. Had they looked into his past history in his campaigns for office, they would have realized this guy was a masterful liar on the sneaky bastard scale of Bill Clinton.
They made the decision post war to go all revisionist and try and pin the blame on Lincoln. It has obviously worked on some people.
Had he not done this. Had he instead sent nothing but a supply ship, nobody could claim that he sent a belligerent force. The trouble is, Lincoln did in fact send a belligerent force.
Only the weak-minded. ;'}
