“The Harriet Lane under your command having been detached from the Collection District of New York & assigned to duty under the Navy Department You are hereby instructed to proceed to within ten miles due east from, and off Charleston…”
By April 1861, federal troops at Fort Sumter in the harbor of Charleston, South Carolina, were running out of supplies. President Abraham Lincoln authorized a relief expedition, including ships with supplies and five hundred soldiers, escorted by four Navy steamers, including the former revenue cutter Harriet Lane. On April 11, the appointed arrival day, she became the first U.S. Naval ship to fire a shot at the beginning of the Civil War.
