United States Revenue and Coast Guard Cutters in Naval Warfare, 1790-1918 [EPUB ebook] 

Covering the history of the U.S. Coast Guard from 1790—when it was called the U.S. Revenue Marine—through World War I, this book describes the service’s national defense missions, including actions during the War of 1812, clashes with pirates, slave ships and Seminole Indians, the Civil War and the Spanish-American War. During World War I the USCG supported U.S. Navy operations across the Atlantic, escorted merchant convoys and engaged in anti-submarine warfare. Original maps are included.
