SS Eastland

The SS "Eastland" was a passenger ship based in Chicago and used for tours on the Chicago River. On July 24, 1915, the ship rolled over onto her side while tied to a dock in the Chicago River. 
A total of 844 passengers and crew were killed in what was the largest loss of life from a single shipwreck on the Great Lakes.
After the disaster, "Eastland" was saved and sold to the United States Navy. After restorations and modifications, "Eastland" was designated a gunboat and renamed USS "Wilmette". She was used primarily as a training vessel on the Great Lakes, and was scrapped after World War II.
