The State Militias were not "National Guard" ("National Guard" became a standard nationwide militia title in 1903, and specifically indicated reserve forces under mixed state and federal control from 1933.), they were state armies. Maryland was invaded by Northern States' Armies touching off serious riots in Baltimore (By businessmen and folks of all economic station, not the gibsmedats of today).

[Sherman Logan]

Maryland was not invaded. MA and other state militias were simply trying to transit MD to get to DC, as requested by the President, which is entirely constitutional.

With VA seceded, do you have suggestions on how troops from other states were supposed to reach and protect the greatly threatened national capital without crossing MD?
