The deadliest fire in U.S. history swept through Wisconsin on Oct. 8, 1871, consuming more than a million acres and killing 1,500 people:

Groups of dead bodies were found within a stone’s-throw of the water. Families rushing down for a breathing place, had been blown upon by the rushing blast and struck lifeless. The ghastly throng huddled, shrieking and bewailing, about the flaring embers, and the terrible roll of the missing was soon called from end to end of the ashen waste. … In a great many instances the human remains were distinguished from animals by the teeth alone. One horror-struck relative recognized the relics of his nephew by a pen-knife imbedded in an oblong mound of ashes.

So why haven’t you heard of it? Because, by a bizarre coincidence, the Great Chicago Fire occurred on the same day.
