Fort Assinniboine’s Company Officers’ Quarters, a six-unit building built in 1880 under the supervision of Major J. C. C. Lee, asserted permanency and sophistication despite geographic isolation. A battlement-topped octagonal turret, a traditional military architectural symbol, distinguished the building, and its architecture impressed a reporter visiting from Fort Benton in 1881, who called the buildings “strikingly handsome.” Usually, two unmarried junior infantry officers lived in each apartment, while unmarried junior cavalry officers lived in a second apartment building that once flanked the northeast end of officers’ row. The almost identical apartments had first floors with a vestibule, a parlor with a brick fireplace and decorative wooden mantel, a dining room, and a kitchen. A staircase with a turned wooden banister led to the second-floor bedrooms, where the officers occupied the two front bedrooms and their servants lived in the two rear bedrooms, reached by a separate staircase. A senior officer lived in the apartment with the tower, which had two additional rooms. The spacious and well-appointed interiors reflected the relative luxury that surrounded even the fort’s junior officers when they were not on patrol.
