You said: “The roots of the war at the corporate/political level was a fight to preserve slavery.”
In January of 1861, the states of the deep South had completed their secession. Within 30 days they had established their Constitution, laws, and court systems.
Offshore and interior trade was progressing uninterrupted. Ships from New York and Boston were docking in Charleston and New Orleans. Banks were open, goods were being harvested, and investments were being conducted.
There was no war.
Two sections were prospering.
April, and with Lincoln now in office, Federal ships appear off Pensacola and Charleston to forcibly dock.
They did not appear without orders from the very top.
