Why not continue? Lincoln went on to say, "Where hostility to the United States in any interior locality shall be so great and universal as to prevent competent resident citizens from holding the Federal offices, there will be no attempt to force obnoxious strangers among the people for that object. While the strict legal right may exist in the Government to enforce the exercise of these offices, the attempt to do so would be so irritating and so nearly impracticable withal that I deem it better to forego for the time the uses of such offices.
The mails, unless repelled, will continue to be furnished in all parts of the Union. So far as possible the people everywhere shall have that sense of perfect security which is most favorable to calm thought and reflection. The course here indicated will be followed unless current events and experience shall show a modification or change to be proper, and in every case and exigency my best discretion will be exercised, according to circumstances actually existing and with a view and a hope of a peaceful solution of the national troubles and the restoration of fraternal sympathies and affections."
Maybe it was all about delivering the mail?
The South opened the war by bombardment of Ft. Sumter. What is the importance of this federal facility? "Because it was a major tariff-collecting facility in the harbor at Charleston. So long as the Union controlled it, the South would still have to pay Lincoln's oppressive tariffs."
That flies in the face on known historical fact, and is makes no sense whatosever if you would only take a moment to think about it. Sumter wasn't staffed by anyone except work men and an officer supervising them prior to Anderson moving there in December 1860. So how would it be 'a major tariff collection facility'? Also, why would the tariff collection point be located miles away from the wharfs where the imports were landed? And what did they do in that Customs House located on East Bay Street?
Slaves that were not in the areas so designated were not covered by it.
Because Constitutionally Lincoln could not do that. And from a strict legal standpoint, Lincoln did not end slavery. He freed the slaves but it took passage of the 13th Amendment to end slavery in those states that had not already done so.
Of course, the winner gets to write the history of the war. And in this case the winner also runs all the schools and they are staffed by people who liked the winner's story. That does not alter the facts, or the real history of this war.
And judging from threads like this it's equally clear that the loser writes the myths.
