In the Mexican-American War, US forces under Winfield Scott launched the first major amphibious assault in US history in the 1847 Siege of Veracruz. During the Crimean War of 1853-1856 the anti-Russian alliance launched an Anglo-French amphibious operation against Russia at Bomarsund, Finland on 8 August 1854. During the American Civil War of 1861-1865 the United States made several amphibious assaults along the coastlines of the Confederate States. Actions at Hatteras Inlet (August 1861) and at Port Royal, South Carolina were the first of many attacks, others occurring on Roanoke Island, NC; Galveston, TX; Fort Sumter, Morris Island and James Island, SC; and several more. The largest such clash happened in January 1865 at Fort Fisher - the largest and most powerful fort in the world at the time - which protected the entrance of Wilmington, North Carolina. The assaulting force consisted of over 15,000 men and 70 warships with over 600 guns.
