But you are obviously not "objective".
You've been drinking pro-Confederate koolaid by the gallon, and it's rotting your brain.
The result is you invent ludicrous fantasies that never happened while ignoring actual history which did happen.
DiogenesLamp: "A murderous conquest.
An oppression.
A killing of innocent people who just wanted to be free of control from Washington D.C."
No, a tragic war premeditated, provoked, started, formally declared and prosecuted by Confederates against the United States, long before any significant response from the Union Army.
Perhaps it would help you to remember that Confederate President Jefferson Davis had been not only a United States Senator, but also a former Secretary of War ('53-57 under Pierce).
In the 1847 Mexican War, Davis, a West Point graduate, had served with great distinction as regimental colonel, under command of his father-in-law, future President Zachary Taylor.
At war's end, Davis was offered promotion to general, but turned it down, accepting instead, appointment to fill a vacant US Senate seat.
From his extensive military & political experience, Davis judged Northern leaders frightened, weak-willed and unable to make a serious military response.
He believed that a major show of force should be enough to force weak Northerners to back down and give his new Confederacy whatever they demanded.
So in early March, 1861, Davis called up 100,000 troops (versus 17,000 in the US Army), and ordered preparations for military assault on Fort Sumter.
That would show them!
But Davis had never met, and knew nothing about Abraham Lincoln.
Lawyer Lincoln's only military command experience was as militia captain during the Black Hawk war (1832).
And Lincoln's top concern was not money, as you've so often asserted, but rather his oath of office: "to preserve, protect and defend the Constitution."
He was also determined, and so publically announced, that if war came, it would not be the Union starting war.
So Lincoln hoped to maintain peaceful relations with the new Confederacy, however, he did not agree with President Buchanan abandoning all US forts, ships, arsenals & mints to Confederates.
Lincoln was determined to hold the two major Federal assets which remained: Fort Pickens at Pensacola, Florida and Fort Sumter at Charleston.
Just as President Buchanan had in January, Lincoln in April, 1861, ordered resupply missions to those two forts, and just as Buchanan had in January, Lincoln's missions were met with violence from Confederates.
But in April, Confederate violence was orders of magnitude higher than previous, a military assault on Fort Sumter which was clearly an act of war against the United States.
So Lincoln went to the Federal "play book" which had been developed many years earlier as response to potential rebellion-insurrections.
He called up 75,000 troops to retake the lost forts, and ordered General Winfield Scott's "Anaconda Plan" to blockade Southern ports.
Davis responded by formally declaring war on the United States, calling up another 400,000 troops (500,000 total), sending military aid to pro-Confederates in Union Missouri, and ordering military supplies (ships, guns, ammo) from abroad.
As Lincoln said in his second inaugural:
While the inaugural address was being delivered from this place, devoted altogether to saving the Union without war, urgent agents were in the city seeking to destroy it without war--seeking to dissolve the Union and divide effects by negotiation.
Both parties deprecated war, but one of them would make war rather than let the nation survive, and the other would accept war rather than let it perish, and the war came."
I think that's as close to the truth of the matter as anyone can get.
Why would Abe put in that sentence? Admitting that the South wanted to negotiate peace and avoid war. Odd seems like a guilty conscious speaking to me.
