The only major operation conducted by the Atlantic Blockading Squadron was the expedition that led to the capture of Hatteras Inlet, North Carolina August 26–29, 1861. This goal of the operation was to deny use of the inlet to Confederate shipping and this was accomplished with few casualties. The operation was also significant for giving the Union a badly needed victory following the Battle of Bull Run, being the first amphibious landing and the first large scale combined Army-Navy operation of the war.
