If there had been a desire on the part of any single State to withdraw from the compact at any time while the number of States was limited to the original thirteen, I do not suppose there would have been any to contest the right, no matter how much the determination might have been regretted. . . .

If they [the founding fathers] had foreseen it, the probabilities are they would have sanctioned the right of a State or States to withdraw rather than that there should be war between brothers.

Doubtless the founders of our government, the majority of them at least, regarded the confederation of the colonies as an experiment. Each colony considered itself a separate government; that the confederation was for mutual protection against a foreign foe, and the prevention of strife and war among themselves. If there had been a desire on the part of any single State to withdraw from the compact at any time while the number of States was limited to the original thirteen, I do not suppose there would have been any to contest the right, no matter how much the determination might have been regretted. The problem changed on the ratification of the Constitution by all the colonies; it changed still more when amendments were added; and if the right of any one State to withdraw continued to exist at all after the ratification of the Constitution, it certainly ceased on the formation of new States, at least so far as the new States themselves were concerned. It was never possessed at all by Florida or the States west of the Mississippi, all of which were purchased by the treasury of the entire nation. Texas and the territory brought into the Union in consequence of annexation, were purchased with both blood and treasure; and Texas, with a domain greater than that of any European state except Russia, was permitted to retain as state property all the public lands within its borders. It would have been ingratitude and injustice of the most flagrant sort for this State to withdraw from the Union after all that had been spent and done to introduce her; yet, if separation had actually occurred, Texas must necessarily have gone with the South, both on account of her institutions and her geographical position. Secession was illogical as well as impracticable; it was revolution. -U.S. Grant Personal Memoirs
