In March 1873, Mackenzie and five companies (A, B, C, E, and K) of the 4th Cavalry were transferred to Fort Clark with orders to put an end to the Mexican-based Kickapoo and Apache depredations in Texas, which had cost an alleged $48 million. On 18 May 1873, Mackenzie, with five companies of the 4th Cavalry, crossed the Rio Grande into Mexico; they then surprised and burned three villages of the raiders near Remolino, Coahuila; the cavalrymen killed nineteen Indians and captured forty-one, with a loss of one trooper killed and two wounded. The soldiers recrossed the Rio Grande into Texas at daybreak the next morning, with some of the men having ridden an estimated in 49 hours. The raid and an effective system of border patrols brought temporary peace to the area. The John Wayne movie "Rio Grande" (part of John Ford's Cavalry Trilogy) is loosely based on this incident.
