You talking about Lincoln, or Quincy Adams, or both?
The Framers thought it anathema that the federal government should, pro bono some faction or other, seek to coerce a State or States. They made it clear in the Federalist. Quincy Adams's contribution was to think about doing just that, successfully, letting prospective success perfume the exercise after the fact.
Fact is, he ginned up a theory to "permit" the government of a federal Union to occupy and reduce to marches, several States of the Union, and deprive them utterly -- indeed, by extension of the logic, all the States -- of sovereignty, by the magic of "reorganizing" their governments. Ipso facto the States become creatures, inferiors, pawns and playthings of the new Sovereign -- you. Because if you own the Government, you want it to be an omnipotent Government and you need brook no impediments like a mere constitution. Right?
I'm talking about Davis not having enough sense to avoid war -- if that was what he wanted.
