The Mounted Patrol Unit is a unit within the Chicago Police Department and is assigned to the Special Functions Division of the Bureau of Patrol. Designated Unit 055, members utilize radio call signs in the 4900 thru 4959 series and operate on Citywide 1. The Mounted Unit provides specialized mounted patrol in selected areas of the City where such patrol can be used effectively. The unit is headquartered at the former South Shore County Club Stables located at 7059 S South Shore Drive.

Since inception of the Mounted Patrol in the parks and Loop area, it has proved invaluable in arrests for thefts, strong-armed robbery, peeping toms, exposures and helped apprehend a bank robber. Because of the excellent visibility afforded an officer on horseback, they can be utilized in numerous situations difficult for motorized vehicles or foot patrols. The unit has lost six horses in the line of duty since its inception.

The unit was organized as the “Mounted Police Force” in 1906 and was created to meet the needs of a congested loop area and was used for traffic and crowd control. Headquartered at 12th and State Streets its compliment consisted of 40 officers. In 1922 the unit was headquartered at Illinois and LaSalle Streets and its compliment consisted of 150 officers. The unit operated mainly in the loop area, its boundaries stretching from Chicago Avenue to 12th Street and Lake Michigan to Halsted Street, until it was disbanded in 1948.

The unit was reorganized as the “Mounted Patrol” in the spring of 1974 and was created for the purpose of aggressively patroling Chicago Parks and other recreational areas. The following personnel were the first assigned to the unit: Sergeants Timothy Gainer and J. Lorenz, Patrolmen J. Brennan, A. Garcia, S. Harris, M. McDonald, Joseph Morici, F. Murczek, J. Murray, J. Petrone, Peter Poholik, G. Preski, H. Radney, and R. Vicari. Ten geldings were purchased for the unit and a contest was held to name them.

The unit quickly expanded and in early 1975 a second batch of twelve horses were purchased and an additional thirteen officers were brought into the unit. The horses were obtained from areas within a 4-state radius of Chicago, Ages ranged from 4 to 8 years, with an average height of 16.0 hands, Mounts had to be either black, brown or chestnut geldings and possess a sound disposition. Prior to purchase, each animal was examined and x-rayed by a Department authorized veterinarian. The units total compliment now boasted 27 men and 22 horses. The officers rotated their mounts approximately every 3 months, working the horses for two shifts with relief.

A contest was once again held to name the new horses. The winning name and school children were:

  • AMITY, submitted by Susan Adamiek, age 13, Holy Innocents School.
  • BUCKINGHAM, submitted by Denise Armenta, age 10, Henderson School.
  • CHASE, submitted by Christopher Menconi, age 5, Ella Young School.

  • “RELAMPAGO” (FLASH), submitted by Martina Ramirez, age 11, Gale School.
  • SAFEGUARD, submitted by Angela Harris, age 12, Ella Young School.
In July 1975, the new mounted officers graduated from the Mounted Patrol’s Training Academy. After 12 weeks of intensive training, the new mounted officers were ready for action. They gave their first public performance during graduation exercises before an audience of relatives, friends, department officials and picnic crowds who gathered to applaud their prowess. Deputy Chief Walter Vallee, Captain James Delaney, Sergeant Timothy Gainer, and Patrolmen Peter Poholik and Joe Morici shared their moments of glory from the sidelines, enjoying the satisfaction of the obvious results of the presentation. One officer was missing from her mount for the graduation exercises. Patrolman Jillian McLaughlin who was a member of the class sustained an injury and did not complete her training for several weeks. She was the first female member of the Mounted Patrol Unit.

Class work, care and grooming, physical anatomy of horses, first aid, stable management, tack study, plus jumping and riding for a minimum of 240 hours were part of the training program. The new mounted officers visited community riding stables, veterinary clinics and lived horses almost every waking moment. Qualifying for this unit called for men and women with five years on the force, who were under 35, weighed less than 180 pounds, no back or kidney problems and no disciplinary action of consequence. Following a preliminary board hearing and questioning by an oral board, applicants were selected on the basis of physical well being, appearance and knowledge of police work.
