North Carolina issues Ordinance of Secession 20 May 1861
Virginia issues Ordinance of Secession 17 April 1861 (ratified 23 May, 1861)
Virginia sent its militia to seize the arsenal at Harpers Ferry on April 17, and began organizing them for that task before the Virginia convention voted for secession. North Carolina seized the U.S. Mint in Charlotte on April 21 and the federal arsenal in Fayetteville on April 22. Virginia organized her army and appointed commanders in violation of the Constitution by April 26. And you want us to believe that they were not participating in the rebellion? In light of those actions, Lincoln's including them in the blockade made perfect sense.
