"The War in Missouri: Gen. Jim Lane’s Negro Brigade Attempt a Raid into Missouri – 4"

"Gen. Jim Lane's Negro Brigade" was not a brigade, not even a regiment, though it will become a full regiment in 1863.
As of "today" it's not yet mustered, at most a Union battalion of six companies, will become the first colored unit to see combat, a year before the 54th Massachusetts.

The First Kansas Colored Infantry Regiment will suffer 344 died during the war, more than any other Kansas unit.

"Editorial: Barbarism of the Rebels – The Emancipation Proclamation – 6"

Several ideas were proposed in the Confederate congress to punish the Union for Lincoln's Emancipation Proclamation.

"The minority of the Committee reported a resolution that 'from this day henceforth all rules of civilized warfare should be discarded,' and that a war of extermination should henceforth be waged."

So there should be no doubt that Confederates were dead-serious about preserving their "peculiar institution".
