In 1868, the Grand Army of the Republic, a veteran’s organization for Union Civil War veterans, called for May 30th to be observed annually as a day to remember the 620,000 Americans killed in the Civil War. Originally called Decoration Day, the May 30th holiday gradually became known as Memorial Day. In 1968, Congress passed the Uniform Monday Holiday Act, moving four holidays, including Memorial Day to specified Mondays to create three-day weekends.
On this Decoration Day, take a moment to remember U.S. Navy Boatswain’s Mate Michael McCormick, who served aboard the U.S.S. Signal, a 190-ton stern-wheel paddle steamer of the type derisively called a “tinclad” for the half-inch steel armor protecting its main deck, sufficient to stop a rifle bullet but offering no protection against cannon shells. Under the plating, the ships were entirely made of wood, Tinclads were cheap, expendable, and, in the words of one naval historian, “complete fire traps.”
On May 4, 1864, the Signal, was proceeding downstream on the Red River in Louisiana when it was fired upon by Confederate cavalry. A running battle ensued for the next four miles until the Signal encountered sister ship U.S.S. Covington and the John Warner, an Army transport ship. Trapped near Dunn’s Bayou near Alexandria, Louisiana, the gunboats exchanged point-blank cannon fire with Confederate field artillery on both banks. At one point in the uneven fight, the Signal was hit 38 times in four minutes.
