Bering Sea Anti-Poaching Operations were conducted in 1891 by the navies and marine corps' of the United States and the United Kingdom of Great Britain and Ireland. Due to the near extinction of the seal population in the Bering Sea, the American and British governments dispatched a squadron of warships to suppress poaching activities, under the command of United States Navy Commander Charles S. Cotton.

African Slave Trade Patrol was part of the Blockade of Africa suppressing the Atlantic slave trade between 1819 and the beginning of the American Civil War in 1861. Due to the abolitionist movement in the United States, a squadron of U.S. Navy warships and Cutters were assigned to catch slave traders in and around Africa. In 42 years about 100 suspected slave ships were captured.
