The attack on USS Minnesota occurred during the later stages of the American Civil War, when the Confederate States Navy was seeking innovative ways to break the Union blockade. Following the successful attack by CSS David on the ironclad USS New Ironsides, Confederate forces continued to develop and deploy torpedo boats as a tactical response to Union naval superiority. The Squib-class vessels were built specifically for this purpose, with four ships of the class constructed in Richmond, Virginia in 1864. CSS Squib, one of these newly constructed vessels, participated in an attack on the Union gunboat USS Minnesota on April 9, 1864, demonstrating the Confederate commitment to using these specialized craft against Union naval forces.
CSS Squib was armed with a single spar torpedo and powered by a steam engine, making it one of the four Squib-class vessels designed for torpedo boat operations. During the April 9, 1864 engagement, Squib attacked and damaged USS Minnesota, achieving a tactical success against a significant Union warship. The attack represented the type of asymmetric naval warfare the Confederates hoped would help counter Union naval dominance in coastal and river operations.
Following the successful attack on USS Minnesota, CSS Squib was subsequently sent to Wilmington, North Carolina, where she was scuttled in February 1865 as Confederate naval capabilities continued to deteriorate. The engagement demonstrated the potential effectiveness of torpedo boats in Confederate naval strategy, even as the broader military situation moved toward Confederate defeat. While Squib achieved temporary success, the overall impact of the Squib-class vessels remained limited, as the other three vessels of the class were eventually lost or destroyed during the final months of the war.
The American Civil War (1861–1865) was the deadliest conflict in American history, killing an estimated 620,000 to 750,000 soldiers and an unknown number of civilians. The Confederate States of America, formed by eleven seceding Southern states, faced the Union in four years of warfare across 23 states and territories. Major engagements included First and Second Bull Run, Antietam (the bloodiest single day in American history, September 17, 1862), Chancellorsville, Gettysburg (July 1–3, 1863), Vicksburg (surrendered July 4, 1863), and Sherman's March through Georgia and the Carolinas (1864–1865). President Lincoln issued the Emancipation Proclamation on January 1, 1863, transforming the war's stated purpose to include the abolition of slavery and enabling the enlistment of approximately 180,000 Black men in the United States Colored Troops. Confederate General Robert E. Lee surrendered to Ulysses S. Grant at Appomattox Court House on April 9, 1865. The war resolved the question of secession and ended American slavery, though Reconstruction would face sustained resistance in its attempt to secure civil rights for formerly enslaved people.
