Nowadays, the blaring siren of a fire truck elicits a sense of awe and urgency as it races through the streets. People pause, marveling at the sleek, red machines with their chrome accents, while firefighters in dark uniforms hurry toward their mission. Yet, this image of modern firefighting is a far cry from the past, when cities depended not on engines of metal, but on the bravery and strength of fire-horses. In those days, citizens gathered in awe to witness the magnificent animals spring into action, playing a critical role in saving lives.
