3)  The unusable pumping station and the heat melting the hoses.

Although the winds accelerated the progression of the fire through the city, it is mainly the inoperability of the pumping station, called La Marine, that prevented the firefighters from doing their work. Normally used to power the water system of the city, it was unfortunately being repaired at the time and was impossible to operate.

At the time, the fire hoses were hung in a tower of the city hall. The heat from the fire was such that the fire hoses began to melt during their deployment. Shortly after, the fire attacked the pumping station, making it permanently unusable.
