was gravely wounded by friendly fire while performing a reconnaissance during the Battle of Chancellorsville. The severity of the wounds required Dr. McGuire to amputate Jackson's left arm. Jackson died of pneumonia a few days later. His last words were recorded by Dr. McGuire as: "Let us cross over the river and rest beneath the shade of the trees". The death of Jackson affected McGuire greatly. He would always remember Jackson with the deepest reverence and served as a pallbearer in Stonewall's funeral. During the Second Battle of Winchester, which was part of Robert E. Lee's invasion of Pennsylvania, McGuire served under Richard Ewell (who by this time had returned to field command). At the Battle of Gettysburg, Dr. McGuire amputated the leg of General Isaac R. Trimble after Pickett's Charge. He later served under General Jubal Early. McGuire was captured at the Battle of Waynesboro in March 1865, but was released and rejoined the Army of Northern Virginia. He was present at the surrender at Appomattox Court House.In May 1862, Jackson's army captured Winchester, Virginia. Among their captured prisoners were seven U.S. army physicians (then called "surgeons"). McGuire wished to see medical personnel treated as non-combatants, so he convinced Jackson to set a precedent by releasing the captured surgeons. With Jackson’s approval, Dr. McGuire drafted an agreement (known afterwards as the "Winchester Accord," which the Federal surgeons signed, saying: “We surgeons and assistant surgeons, United States Army, now prisoners of war, do give our parole of honor on being unconditionally released to report in person, singly or collectively to the Secretary of War in Washington City as such and that we will use our best efforts that the same number of medical officers of the Confederate States Army now prisoners or may hereafter be taken be released on the same terms. And furthermore we will on our honor use our best efforts to have this principle established – the unconditional release of all medical officers taken prisoners of war hereafter.” The released surgeons honored their agreement to take the message to Washington and almost immediately it had the desired effect. On June 6, 1862, the United States immediately and unconditionally released all Confederate surgeons being held as prisoners of war. Thereafter, for the remainder of the war, all captured medical personnel were immediately released so as not to impede their live-saving work, saving an untold number of lives. As
