I believe this was what you were looking for.

Generally, it worked like this (at least for Union Armies):
The President issued a call for volunteers (1st call April, 1862 in response
to the firing upon of Ft. Sumter, 2nd call August 1862)), and each state was
given a quota of troops that it needed to raise. Towns and cities would
hold "war meetings" featuring patriotic speaches, martial music, cheers for
the Union, etc. where young men would enlist into companies composed of
other young men from same geographic area (same county - closely located
towns, etc). The State Adjutant General was responsible then for organizing
(and also raising volunteers) these companies into regiments, and early on
the states were responsible for arming and equipping the volunteers (to be
reimbursed later by the Feds). Companies would be organized by the State
Adj Genl into regiments, and the regiments mustered into U.S. Service at
training camps. The War Dept. then organized the regiments into brigades,
divisions, corps, etc. Once a regiment left its home State, it came under
the command and control of the War Dept. This system of course, was
augmented later in the War by the Draft, and in some cases regiments were
composed entirely of drafted men, and in some cases, existing regiments in
the field were supplemented by drafted men to replace those who had died or
One did not simply "pick up their musket" and march off to War - a
beaurocratic system was firmly in place to effectively raise and manage army
regiments, and then, as now, the armies left a huge paper trail in its wake.
Everything was carefully documented in duplicate and triplicate - some
things never change!
I can't really comment on how Confederate regiments were raised, but do know
that those Notherners that wished to fight for the South did indeed need to
go South to enlist. Company G of the 15th Tennessee Vol. Inf. was one of
those units - made up of men from Southern Illinois that made their way to
the Kentucky/Tennessee border to enlist in Conf. States service.
Hope this helps.
