I’ve always found it interesting that the confederate army at Manassas was the Army of the Potomac, while the Union army was the Army of Northeastern Virginia. It’s like afterwards, both commanders decided to switch names.Â
And on a similar note: “Many [Confederate volunteers] were from state militia outfits which had their own state-issued uniforms, and in the early battles some Confederate units who wore dark blue uniforms were often mistaken on the field of battle for the enemy. Conversely, many Union units which were originally militia units went to war wearing grey.”
