Boston Police Department Mounted Patrol unit is established.

It initially consists of a single officer on horseback assigned to patrol the Mill Dam Road. The oldest municipal police mounted unit in the U.S., it grows to 74 officers by 1874 and includes as many as 100 horses at one time. The unit’s stables relocate to Faulkner Farm, the former Brandegee estate at 165 Allandale Street, in 1964. The unit is disbanded due to budget cuts in 2009, with five of its horses loaned out to the New York City Police Department and four to the Plymouth County Sheriff’s Department. Currently, there are planes to revive the unit.
