The Mississippi River Squadron was a naval force established during the American Civil War to control the Mississippi River and its tributaries. This squadron played a crucial role in the Union's strategy to divide the Confederacy and secure vital supply routes. It consisted of various types of vessels, including gunboats and transport ships, which were used for both combat and logistical support. The squadron was instrumental in several key battles, such as the Siege of Vicksburg, which was a turning point in the war. By gaining control of the river, the Union forces, led by figures like Admiral David Porter, were able to disrupt Confederate supply lines and enhance their military operations across the region.
