Ok, March 4, 1861. That was still an army 6 or 7 times larger than the U.S. army. And larger than the call Lincoln originally made to suppress the rebellion.
In response to Lincoln's threats in his first inaugural speech (which was, as you know, widely viewed as a declaration of war), the Confederate Congress passed the following on March 6, 1861 (my emphasis below):
The Congress of the Confederate States of America do enact, That in order to provide speedily forces to repel invasion, maintain the rightful possession of the Confederate States of America in every portion of territory belonging to each State, and to secure the public tranquility and independence against threatened assault, the President be, and he is hereby authorized to employ the militia, military and naval forces of the Confederate States of America, and to ask for and accept the services of any number of volunteers, not exceeding one hundred thousand, who may offer their services, either as cavalry, mounted riflemen, artillery or infantry, in such proportion of these several arms as he may deem expedient, to serve for twelve months after they shall be mustered into service, unless sooner discharged.
Only portions of that number were called up before Lincoln's battlefleet reached South Carolina's waters.
I'm off for the rest of the day, non-seq, heading out to enjoy barbeque and country music among the cowboys and bikers at Luckenbach. God bless Texas!
A. So what? You in the habit of telling other countries how big an army they (don't) need?
B. There was no rebellion, but you knew that. Insurrection is certified to the Congress or the President by the legislature or the governor of the affected State. Lincoln knew that when he solicited Sam Houston with a presidential junk-mail letter, asking Gov. Houston to certify insurrection in Texas so Lincoln could send him federal troops.
Nobody in the departing States certified insurrection, for the very good reason that there was no rebellion. Entire States acting on their reserved rights and powers do not a "rebellion" make. But you knew that.
