The Peshtigo Fire. October 8, 1871.
Coincidentally, the same day as the Great Chicago Fire (unrelated).

Interesting that on the wikipage they show a surviving piece of wood. There are theories on the destruction of these horrific fires but the trees are still standing. Also noted at the bottom:
“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 one of Tokyo by incendiary devices resulted in death tolls comparable to the atomic bombings of Hiroshima and Nagasaki.[29]”
I can’t imagine the horror. Been doing other research about evil and blood pressure is rising again.
