Paul Butler was an avid photographer and in 1933 he took his camera to Camp Grant and photographed the 106th Cavalry campsite and the drilling cavalrymen and mounted band. These rare views are presented courtesy of the Butler Family Archive.

In the early 1920s, even before the Black Horse Troop was formed (1929) and Paul Butler became its commander, his Oak Brook polo grounds in Chicago's western suburb, Hinsdale, was a popular venue for the sport. The polo league included independent and military teams.

City Pays Tribute Both to Living and Dead.

In a great parade down Michigan avenue, in special services at the city's cemeteries, and in the hearts of its citizens, Chicago observed Memorial day yesterday and paid tribute to its war heroes, living and dead.
Crowds See Chicago Parade.
Chicago's main interest was in the Michigan avenue parade. Hours before the first unit began marching from Chicago avenue the sidewalks were lined as far south as the Logan monument in Grant park.
It was regarded as Chicago's greates Memorial day parade. For two hours and a half the gayly uniformed units streamed past the reviewing stand.
Leading the line of the march were six platoons of mounted police of the Chicago force.
Black Horse Troop in Line.
Behind them came the Black Horse Troop of the Illinois National Guard, with its mounted band. At the head was Capt. Paul Butler, leading the ranks of coal black horses, with the men resplendent in smart uniforms of black and white, topped by dragoon helmets.

November 25, 1931

Capt. Chauncey McCormick commander of the Black Horse troop has resigned the command, it was learned yesterday. First Lieutenant Paul Butler, next in succession, is acting as troop commander. Capt. McCormick headed the troop for the last time at the regular drill meeting Monday night.

Chauncey McCormick, who had agreed to command the Troop from its inception two years prior, left because of buisiness pressures.

After Paul Butler's command of the Troop ended in the mid-1930s, he remained active in the horse and polo community and at the Chicago Avenue Armory:

October 3, 1947:
Horse Show Opening
     The opening of the fourth annual Chicago Horse show tonight in the Chicago Avenue Armory at 234 E. Chicago av. will be the occasion for a round of gala dinner parties beforehand, one of the largest of which will be given by John F. Cuneo, chairman of the show, in the Camelia House. Gov. and Mrs. Green will be among his guests, as will August A. Busch of St. Louis.
     Among others who will entertain at the Camelia House tonight before the show will be Paul Butler, president of the Chicago Horse Show association, and Mrs. Butler.

When the 106th Cavalry regiment was mechanized in 1942 for service in the Second World War, the Black Horse Troop disbanded. It never recovered its status as a ceremonial unit.

After WWII, former Black Horse Troop members formed an American Legion post and in ten years the Troop, diminished for lack of membership, disolved. In the mid-1980s, another incarnation of the Black Horse Troop Association appeared in the Chicago area and appeared in suburban parades.

The Chicago History Museum maintains the Black Horse Troop's archive as part of its manuscript collection:

Chicago Black Horse Troop Association. Chicago Blace Horse Troop Association records, 1929-1955.
Charter (1929 June 27), constitution and by-laws, minutes of annual and special meetings of directors and members, financial records, etc. in leather-bound volume and records of the association that did fund-raising and supported the Chicago Black Horse Troop and Mounted Band also known originally as the Headquarters Troop and Band of the 106th Cavalry, Illinois National Guard, 33rd Division. The Black Horse Troop performed in many parades and military shows.

From within the museum's collection I learned that the newly formed Chicago Black Horse Troop Association had passed a resolution to recognize Paul Butler's son and grandson as honorary members of the Troop.
