All these calls for enlistment were responded to by the loyal States with the greatest promptness, and the numbers called for were more then furnished, notwithstanding the failure of some of the Southern non-seceding States to promptly fill their assigned quotas. Governor Burton of Delaware (April 26th) issued a proclamation for the formation of volunteer companies to protect lives and property in the State, not to be subject to be ordered into the United States service, the Governor, however, to have the option of offering them to the general government for the defence of the Capital and the support of its Constitution and laws. Governor Hicks of Maryland (May 14th) called for four regiments to serve within the limits of the State, or for the defence of the Capital of the United States. Governor Letcher of Virginia (April 16th) spitefully denied the constitutionality of the call for troops "to subjugate the Southern States." Governor Ellis of North Carolina (April 15th) dispatched that he regarded the levy of troops "for the purpose of subjugating the States of the South as in violation of the Constitution and a usurpation of power." Governor Magoffin of Kentucky (April 15th) wired: "Your dispatch is received. In answer I say emphatically, Kentucky will furnish no troops for the wicked purpose of subduing her sister Southern States." Governor Harris of Tennessee (April 18th) replied: "Your requisition, in my judgment, is illegal, unconstitutional, and revolutionary in its objects, inhuman and diabolical, and can not be complied with." Governor Rector of Arkansas (April 22d) responded: "None will be furnished. The demand is only adding insult to injury."(25) Four of the slave-holding States thus responding to the President's call, to wit: Virginia, Arkansas, Tennessee, and North Carolina, soon joined the Confederate States; Maryland, Missouri, Kentucky, and Delaware remained in the Union, and, later, filled their quotas under the several calls for troops for the United States service, though from each many also enlisted in the Confederate Army. The Union volunteers were either hastened, unprepared by complete organization or drill, to Washington, D. C., to stand in its defence against an anticipated attack from Beauregard's already large organized army, or they were assembled in drill camps, selected for convenience of concentration and dispersion, to the scenes of campaigns soon to be entered upon.
