IIRC, on the day of the Chicago fire, a fire struck a Wisconsin town with even more deadly effect and yet less was written of it at the time.
On the evening of October 8, 1871 devastating fires erupted at virtually the same moment in three different states in the region of the Great LakesWisconsin, Illinois, and Michigan. The outbursts included the notorious Chicago fire, but also an even more devastating fire in Wisconsin, the worst in U.S. history, covering some 400 square miles. At the same time, wildfires also erupted across much of Michigan.
