The USS Wave was a sidewheel steamboat built in 1863 at Monongahela, Pennsylvania, originally named Argosy No. 2. Constructed during the American Civil War, she was acquired by the Union Navy on 14 November 1863 and subsequently renamed Wave. The vessel was converted into a "tinclad" gunboat, a type of lightly armored steamer equipped with shallow draft for river operations. In early 1864, USS Wave was assigned to the West Gulf Blockading Squadron, where she initially operated off New Orleans, Louisiana. Her primary role was supporting the Union blockade of Confederate waterways by patrolling and engaging enemy vessels. On 15 April 1864, she received orders to move to Calcasieu Pass, located at the mouth of the Calcasieu River in southwestern Louisiana. She arrived there on 24 April, accompanying USS Granite City to collect Confederate renegades and seize arms, saddles, and harness that could be used militarily by the Confederacy. The vessel's service came to a dramatic end on 6 May 1864. While at anchor in the Calcasieu River, Wave and Granite City were surprised by the entire garrison of Sabine Pass. Granite City surrendered after about 45 minutes of combat, but Wave fought on for another 45 minutes despite heavy damage—her engines and movable guns disabled, with eight crew wounded. Ultimately, her crew destroyed documents and materials on board to prevent their capture, and the commanding officer surrendered the vessel to Confederate forces. Following her capture, the USS Wave was repurposed by the Confederates as a cargo steamer. The final fate of the vessel remains uncertain, though it is believed to have been destroyed by retreating Confederate forces. The USS Wave’s service highlights the fluid and often perilous nature of naval operations in the Civil War, particularly in riverine environments where gunboats like her played a vital role in Union efforts to control strategic waterways.
