The Civil War Era

The TrenT inCidenT
During the fall of 1861, as President
Lincoln tried to prod General
McClellan into action, he also dealt
with another diffi cult situation. On
November 8 a U.S. Navy vessel,
the U.S.S. San Jacinto, intercepted a
British mail ship, the Trent, en route
from Havana, Cuba, to the Virgin
Islands. Two Confederate diplomats—
John Slidell from Louisiana and James
Mason of Virginia—bound for Paris
and London were taken prisoner by
the commander of the U.S. ship,
Captain Charles Wilkes. Slidell had
served in Congress during the 1840s
and had negotiated with the Mexican
government during the Mexican–
American War. His brothers-in-law
included the Southern General P.G.T.
Beauregard and American Naval
Commodore Matthew Perry.
The two Southerners were on a
diplomatic mission at the time of
their capture. The South was seeking
support for its war efforts from the
British and French governments.
If either European power had
entered the war, either militarily
or with economic aid, the South
would have gained signifi cantly
from their involvement. Realizing
the importance of his two captives,
Captain Wilkes took them to Boston
and placed them in a Union prison.
The Northern press learned of the
Trent Incident, and touted Wilkes as a
hero. Congress even struck a special
medal to honor him.
However, the British government
was outraged. A U.S. Navy vessel had
forcefully detained a British ship. For
a time there was some talk in London
of Britain going to war with the
Union over the incident. The Lincoln
administration soon intervened.
Secretary of State William Seward
declared that the American war
vessel had taken illegal steps by
imprisoning the two Confederate
diplomats and not bringing the case
before an admiralty court. Although
the British Prime Minister, Viscount
Palmerston, delivered an ultimatum to
the president, demanding an apology,
Lincoln merely released Mason and
Slidell by the end of December. The
president never formally apologized
for the Navy’s actions. Mason and
Slidell resumed their voyage to
England but failed in their mission.
