jeffersondem: "You probably intended to say Delaware is notable for being the only Southern state from which no Confederate regiments or militia groups were assembled.

Here's what I intended to quote from this source:

"While most Delaware citizens who fought in the war served in the regiments of the state, some served in companies on the Confederate side in Maryland and Virginia Regiments.
Delaware is notable for being the only slave state from which no Confederate regiments or militia groups were assembled."

jeffersondem: "If memory serves, you contend Delaware is a Southern state."

Delaware was one of four Border South states (Delaware, Maryland, Kentucky, Missouri) -- slave states which never voted to secede.
Those Border States did also provide troops for the Confederacy, on the order of three Union to one Confederate. But of the four, Delaware had the fewest slaves in 1860 and provided fewer troops for the Confederacy, both in numbers and percent compared to Union troops.

“Here's what I intended to quote from this source: . . .”

It's fine that you use Wikipedia. But you should read the article before you use it to support your argument.

The first sentences of the article says: “Delaware is a state located in the Mid-Atlantic and/or Northeastern regions of the United States. It is bordered to the south and west by Maryland, to the northeast by New Jersey, and to the north by Pennsylvania.

This repudiates your contention that Delaware is a Southern state. Just because it had slaves did not make it a Southern state. All of the original Northern states were slave states at one time. And after they moved to a different labor system they were still Northern states.

And your contention that Delaware was a “border state” is wrong too. Delaware borders Maryland, which was an actual border state to the Southern Confederacy. Maryland never seceded; fought for the Union cause. Like all the original states north and south, Maryland was a slave state.
