As General George Meade assumed command he ordered all Union Corps into rapid motion. This morning the Second Corps departed Monocacy Junction and marched over thirty-two miles to Uniontown in their longest single-day march during the Civil War. Although the day was hot only fifteen men were overtaken by the heat, as two men dropped from the ranks and thirteen needed transport by ambulance.1
