General Winfield Scott enters Mexico City, captured during the Mexican-American War. At his side is a "Jewish Doctor": Army surgeon Dr. David Camden de Leon of South Carolina.
A U.S. Army surgeon nicknamed “the fighting doctor,” Dr. de Leon on a number of occasions took over command of his unit when regular officers were incapacitated, rallying the troops and leading the charge against the enemy. For these actions he twice received the thanks of congress.
Following the war, de Leon remained in the army until the outbreak of the American Civil War. A native of South Carolina, he resigned his commission on 19 February 1861 and joined the Confederate Army, where he was appointed Surgeon General. Unhappy with a desk job, the restless de Leon soon transferred to a combat command and saw active service in the frontlines for the rest of the Civil War.
