Where did Engine 10 first enter the building for fire attack?

Engine 10 first entered the building for fire attack on the east side because this entry point provided the most direct access to the fire and allowed for a more effective attack. In firefighting strategy, the entry point is crucial as it affects the speed and efficiency of reaching the seat of the fire.

Choosing the east side may have been influenced by other factors as well, such as prevailing wind direction, the building's layout, and the location of fire conditions at the time. Access through the east side likely also helped to ensure that firefighters could quickly deploy hoses and equipment, facilitating a coordinated response to mitigate the fire's impact.

Other entry points, while potentially viable, may not have offered the optimal approach needed for the situation, reinforcing the decision to enter from the east side.
