Alexander Slidell Mackenzie

Alexander Slidell Mackenzie (April 6, 1803 – September 13, 1848), born Alexander Slidell, was a United States Navy officer, famous for his 1842 decision to execute three suspected mutineers aboard a ship under his command in the Somers Mutiny. Mackenzie was also an accomplished man of letters, producing several volumes of travel writing and biographies of early important US naval figures, some of whom he knew personally.

Mackenzie was the brother of Senator John Slidell of Louisiana, who was later involved in the American Civil War's ''Trent'' Affair.

Mackenzie was the captain of USS ''Somers'' when it became the only US Navy ship to undergo a mutiny, which led to executions, including Philip Spencer, the 19-year-old son of the Secretary of War John C. Spencer.

Mackenzie's handling of the ''Somers'' Mutiny, including its lack of a lawful court martial, was highly controversial and public opinion ran against him. The mutiny proved the need for systematic training of cadets before they went to sea. In 1845, Secretary of the Navy George Bancroft seized on the Somers affair as a reason to establish the United States Naval Academy. Provided by Wikipedia
