The Home Squadron was part of the United States Navy in the mid-19th century. Organized as early as 1838, ships were assigned to protect coastal commerce, aid ships in distress, suppress piracy and the Atlantic slave trade, make coastal surveys, and train ships to relieve others on distant stations. It was discontinued in 1861 after the outbreak of the American Civil War, when the Union blockade forced a reassignment of ships to close off Southern ports.
