On this date in 1861, Colonel Robert E. Lee wrote a letter to his son, Curtis, regarding the secession crisis. You might wonder what was so momentous about this, so please read the following:
As an American citizen, I take great pride in my country, her prosperity and her institutions, and would defend any State if her rights were invaded. But I can anticipate no greater calamity for the country than the 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.
Unfortunately, just a few months later, on April 12, Fort Sumter was fired upon, and thus began the Civil War.
