During the
American Civil War,
Michigan was armed with a 30-pounder
Parrott rifle, five 20-pounder Parrott rifles, six 24-pounder
smoothbores, and two 12-pounder boat
howitzers. The
Confederate States of America considered launching attacks against the
North from the
Province of Canada. Early in 1863,
Lieutenant William Henry Murdaugh,
CSN, planned to lead a group of Confederate naval officers to Canada where they would purchase a small steamer, man her with Canadians and steam to Erie to board
Michigan and use her against
locks and shipping on the Great Lakes. However, Confederate President
Jefferson Davis did not approve the plan.
Michigan cruised on the Great Lakes during most of the war providing an element of stability and security. On 28 July 1863, a short time after
New York City had been seriously shaken by riots, its Virginia-born
Commander John C. Carter reported from
Detroit, "I found the people suffering under serious apprehensions of a riot....The presence of the ships perhaps did something toward overawing the refractory, and certainly did much to allay the apprehensions of the excited, doubting people." During August 1863,
Michigan was called on for similar service in
Buffalo, New York. During 1864, rumors of Confederate conspiracies in Canada were heard again. In March,
Secretary of the Navy Gideon Welles ordered
Michigan to be "prepared for active service as soon as the ice will permit." In the autumn, the Confederates finally struck. Led by Acting Master
John Yates Beall, 20 Confederates embarked on the
steamer as passengers and soon seized her. They next captured and burned the steamer . Meanwhile, Captain Charles H. Cole,
CSA, a Confederate agent in the Lake Erie region, was attempting to gain the trust of
Michigans officers as the
Michigan lay off
Johnson's Island helping to guard Confederate prisoners. However, Commander Carter discovered Cole's
duplicity and had him arrested before Beall reached Johnson's Island on
Philo Parsons. When the prearranged signals from shore were not made, Beall reluctantly abandoned his plan and retired to Sandwich (now
Windsor, Ontario) where he stripped and burned
Philo Parsons. ==Later U.S. Navy service==
