Good lord, Warren, leave the poor guy a reason to read! There was some statement attributed to Lee, perhaps this one made to Preston Blair, when Lee was offered command of the Union Forces:
"Mr. Blair, I look upon secession as anarchy. If I owned the four millions of slaves in the South, I would sacrifice them all to the Union; but how can I draw my sword upon Virginia, my native State?"
Lee saw himself less as an American than as a Virginian, first, last, and always.
Here's another well known quote, written to his daughter in January of 1861:
I can anticipate no greater calamity for the country than a dissolution of the Union. It would be an accumulation of all the evils we complain of, and I am willing to sacrifice everything but honor for its preservation. I hope, therefore, that all constitutional means will be exhausted before there is a resort to force. Secession is nothing but revolution. The framers of our Constitution never exhausted so much labor, wisdom, and forbearance in its formation, and surrounded it with so many guards and securities, if it was intended to be broken by every member of the Confederacy at will. It is intended for 'perpetual Union,' so expressed in the preamble, and for the establishment of a government, not a compact, which can only be dissolved by revolution, or the consent of all the people in convention assembled. It is idle to talk of secession: anarchy would have been established, and not a government, by Washington, Hamilton, Jefferson, Madison, and all the other patriots of the Revolution. … Still, a Union that can only be maintained by swords and bayonets, and in which strife and civil war are to take the place of brotherly love and kindness, has no charm for me. I shall mourn for my country and for the welfare and progress of mankind. If the Union is dissolved and the Government disrupted, I shall return to my native State and share the miseries of my people, and, save in defense will draw my sword on none.
