Colonel Robert E. Lee was a United States Army officer at this time and had one of the most difficult decisions to make. He was recognized as a man of great military ability, and the high regard which the Federal government had for him was expressed in the tremendously responsible position offered to him by President Lincoln. Lincoln was familiar with his great military strategy which had been followed in the Mexican War, his efficient administration as Superintendent of West Point, his excellent cavalry supervision on the frontier and his carefully planned capture of John Brown and his raiders at Harper's Ferry. Consequently, on April 18, President Lincoln had offered him the command of the Union forces. Lee realized the wonderful honor for which he had been selected and was deeply appreciative. However, he was a Virginian, and, after his state had seceded from the Union, he believed that there was no choice in the matter. His love of country was great, but the love of his state and his fellowmen was greater. Therefore, he sadly declined Lincoln's offer and stated that "though opposed, to secession and deprecating war, I could take no part in an invasion of the Southern States." Thus, as soon as Virginia seceded from the Union, he resigned his United States Army Commission on April 20 with the words: "Sir: I have the honor to tender the resignation of my commission as Colonel of the first regiment of cavalry. Very respectfully, your obedient servant--Robert E. Lee." Lee then went to Richmond at the invitation of the convention and was made Major-General and Commander-in-Chief of the Virginia forces on April 23. It should be noted here that Virginia did not have an aggressive, warlike attitude toward the Union. Governor John Letcher is quoted as speaking to Robert E. Lee in the convention itself in the following manner: "Yesterday, your mother, Virginia, placed her sword in your hand upon the implied condition that we know you will keep to the letter and in spirit, that you will draw it only in her defense, and that you will fall with it in your hand rather than that the object for which it was placed there shall fail."
