The fire started at about 9 p.m. on Sunday, October 8th, in or around a small barn that bordered the alley behind 137 DeKoven Street. he barn was the first building to be consumed by the fire, but the official report could not determine the exact cause of it.
The fire's spread was aided by the city's overuse of wood for building, a drought prior to the fire, and strong winds from the southwest that carried flying embers toward the heart of the city. The city did not react quickly enough, and at first, residents were not concerned about it, not realizing the high risk of conditions. The firefighters were tired from having fought a fire the day before. The firefighters fought the flames through the entire day and became exhausted. As the fire jumped to a nearby neighborhood, it began to destroy mansions, houses and apartments, most made of wood and dried out from the drought. After two days of the fire burning out of control, rain helped douse the remaining fire. City officials estimated that more than 300 people died in the fire and over 100,000 were left homeless
