Here is more on the subject of martial law and habeas corpus in the Confederacy:
"The Confederate Congress declared martial law, prohibited the sale of alcohol, and suspended the writ of habeas corpus.

"Although there were protests, mostly directed at the Confederate government, most Virginia citizens accepted these limits on their freedoms as the price of military victory."
