High Quality Content by WIKIPEDIA articles! The Niagara was a 245-foot (75 m) long sidewheel palace steamer launched in 1846. Like the others of its kind, it carried passengers and cargo around the North American Great Lakes. It was owned by the Collingwood Line. On September 23, 1856, the Niagara left Sheboygan, Wisconsin headed for Port Washington, Wisconsin, on Lake Michigan, carrying 170 passengers and a heavy load of cargo. Fire broke out in the area of the engine room at around 6:00 pm, and the steam engines and the paddlewheels soon stopped. The steamer, which was 4 5 miles offshore, quickly became engulfed in flames and smoke. Efforts to use the fire hose were unsuccessful. The passengers panicked while trying to board the lifeboats, capsizing all but one of them. Many jumped overboard into the water, which was reported to be too cold for anyone to survive in it.
