The Peshtigo fire was a very large forest fire that took place on October 8, 1871, in northeastern Wisconsin, including much of the Door Peninsula, and adjacent parts of the Upper Peninsula of Michigan. The largest community in the affected area was Peshtigo, Wisconsin. It burned approximately 1,200,000 acres (490,000 ha) and was the deadliest wildfire in American history,[1] with the estimated deaths of around 1,500 people,[1] and possibly as many as 2,500.[2]

Occurring on the same day as the more famous Great Chicago Fire, the Peshtigo fire has been largely forgotten.[3][4] On the same day as the Peshtigo and Chicago fires, Holland and Manistee, Michigan (across Lake Michigan from Peshtigo), and Port Huron at the southern end of Lake Huron also had major fires, leading to various theories by contemporaries and later historians that they had a mutual cause.



The setting of small fires was a common way to clear forest land for farming and railroad construction. On the day of the Peshtigo fire, a cold front moved in from the west, bringing strong winds that fanned the fires out of control and escalated them to massive proportions.[5] A firestorm ensued. In the words of Gess and Lutz, in a firestorm "superheated flames of at least 2,000 degrees Fahrenheit ... advance on winds of 110 miles per hour or stronger. The diameter of such a fire ranges from one thousand to ten thousand feet ... When a firestorm erupts in a forest, it is a blowup, nature's nuclear explosion ... "[6]:101

By the time it was over, 1,875 square miles (4,860 km2 or 1.2 million acres) of forest had been consumed,[7][8][9] an area fifty percent larger than the U.S. state of Rhode Island. Twelve communities were destroyed.

An accurate death toll has never been determined, because local records were destroyed in the fire. Between 1,200 and 2,500 people are thought to have lost their lives. The 1873 Report to the Wisconsin Legislature listed 1,182 names of deceased or missing residents.[10] In 1870, the Town of Peshtigo had 1,749 residents.[11][12] More than 350 bodies were buried in a mass grave,[13] primarily because so many had died that no one remained alive who could identify all the bodies.

Making for the river

The fire jumped across the Peshtigo River and burned on both sides of the inlet town.[14] Survivors reported that the firestorm generated a fire whirl (described as a tornado) that threw rail cars and houses into the air. Many escaped the flames by immersing themselves in the Peshtigo River, wells, or other nearby bodies of water. Some drowned while others succumbed to hypothermia in the frigid river. The Green Island Light was kept lit during the day because of the obscuring smoke, but the three-masted schooner George L. Newman was wrecked offshore, although the crew was rescued.[15]

At the same time, another fire burned parts of the Door Peninsula; because of the coincidence, some incorrectly assumed that the fire had jumped across the waters of Green Bay.[16][Note 1] In Robinsonville (now Champion) on the Door Peninsula, Sister Adele Brise and other nuns, farmers, and families fled to a local chapel for protection. There they participated in prayers and devotions to the Virgin Mary. Although the chapel was surrounded by flames, it survived.[17][18][19] Those gathered at the chapel considered their survival a miracle.[19]

Comet theoryEdit

One speculation, first suggested in 1883, is that the occurrence of the Peshtigo and Chicago fires on the same day was not just a coincidence, but that all the major fires that occurred in Illinois, Michigan and Wisconsin on that day were caused by the impact of fragments from Biela's Comet. This theory was revived in a 1985 book[20][21] and investigated in a 2004 paper to the American Institute of Aeronautics and Astronautics.[22] Scientists with expertise in the area argue that meteorites cannot ignite a fire, as they are cold to the touch when they reach the Earth's surface,[23] and there are no credible reports of any fire anywhere having been started by a meteorite.[23][24]

Additionally, various aspects of the behaviors of the Chicago and Peshtigo fires attributed to extraterrestrial agency have more mundane explanations.[25] In any event, no external source of ignition was needed; numerous small fires from land-clearing operations and other causes were already burning in the area after a tinder-dry summer,[6][26] generating so much smoke that the Green Island Light was kept lit continuously for weeks before the main fire.[27] All that was needed to generate the firestorm, as well as other fires in the Midwest, were the winds from the front that moved in that evening.[26]


The Peshtigo Fire Museum, just west of U.S. Highway 41, has a small collection of artifacts from the fire, first-person descriptions of the event, and a graveyard dedicated to victims of the tragedy. A memorial commemorating the fire was dedicated on October 8, 2012 at the bridge over the Peshtigo River.[28]

The chapel where Sister Adele Brise and others sheltered from the fire has become the National Shrine of Our Lady of Good Help. The site is a Marian shrine, where visitors can make religious pilgrimages.[19]

The combination of wind, topography and ignition sources that created the firestorm, primarily representing the conditions at the boundaries of human settlement and natural areas, is known as the Peshtigo Paradigm.[29] The condition was closely studied by the American and British military during World War II to learn how to recreate firestorm conditions for bombing campaigns against cities in Germany and Japan. The bombing of Dresden and the even more severe bombing of Tokyo by incendiary devices resulted in death tolls comparable to the atomic bombings of Hiroshima and Nagasaki.[29]
