caption_attribution_description: English: The iron sidewheeler USS Michigan (1843), as USS Wolverine (IX-31) late in her life.
context_page_description: The Great Lakes Patrol was carried out by American naval forces, beginning in 1844, mainly to suppress criminal activity and to protect the maritime border with Canada. A small force of United States Navy, Coast Guard, and Revenue Service ships served in the Great Lakes throughout these operations. Through the decades, they were involved in several incidents with pirates and rebels.
  The patrol was ended in 1920 when the US Coast Guard assumed full command of the operations as part of the Rum Patrol. This was initiated during the Prohibition era to try to reduce or end liquor smuggling from Canada across the rivers and lakes, a difficult task.
