Here is what Burns and his source books did not tell you:
1. The slave trade was a New England and European enterprise,
2. At the time Lincoln ordered a Federal Naval force to invade Charleston in April of 1861,all three branches of the Federal government had endorsed slavery.
3. After secession, the federal government lost over 80 per cent of its revenue.
4. The City of New York was in discussion to secede from the Union.

2. At the time Lincoln ordered a Federal Naval force to invade Charleston in April of 1861,

Lincoln ordered the Navy to resupply an existing US military installation. That is not an "invasion".

Further reading did uncover the above facts. The importation of slaves had ended by the time the Civil War began so the question of who began the slave trade was moot.
