M1875 Mountain Gun

It broke down into two loads for easier mule transport. Another pack mule was required for its ammunition. An 1878 Ordnance Report from Brigadier-General Steven Vincent Benet narrates part of the history of this gun, stating: Early in 1876, Colonel Miles, Fifth Infantry, suggested that a light field-gun weighing less than 500 pounds be provided for service on the plains, to replace the obsolete mountain howitzer. The subject was submitted to the Ordnance Board for consideration, with the remark 'that a rifled gun, probably a breech-loader, that can travel with cavalry, and has an effective shell range beyond that of rifled small arms, not less than 1,500 yards, would probably meet the requirements of the service'. While under consideration, Mr. Hotchkiss presented for examination and trial a light breech-loading rifle that gave promise of efficient service on the frontier, and fulfill the conditions of mobility, range, and accuracy. One was procured, and issued to the Department of Dakota in 1877, and was used in the field that summer. It weighs 116 lbs, and its caliber is 1.65 inches. It uses a charge of 6 ounces of powder, and a percussion shell weighing 2 pounds. While many defects in its mechanism, and in the carriage and ammunition, have been pointed out after the experience of a campaign, showing that modifications are desirable to add to its effectiveness, it did excellent work. I am informed that Colonel Miles expressed himself satisfied that it had rendered efficient service, and was a valuable weapon.
