I am publishing an 1872 Directory of Fireman for the City of Chicago. It includes railroads and Chicago businesses. I researched the book from the U.S. Business Directory of 1872, among other references. 1872 was the year after the great conflagration, i.e the Great Chicago Fire of October 8-10, 1871. In this era firefighting was handled by steam engines. They were often pulled by teams of horses.
New firefighter, Rocky Hill, arriving at his first fire is confronted by a frantic mother shouting, "Save my Baby, Save My Baby." While his partners attack the fire, Rocky, his heart pounding with the urgency of the situation, crawls through the upstairs searching for the baby trapped in her crib. Will he find her in time?
