Normally, troops were mustered inside or right in front of the barracks. So the cavalry men were surprised to hear the orders to meet half a mile outside the fort itself. But a few of them knew what that meant. They hustled out, and the others caught up. Despite the distance to the muster point, not a man among them was late to the call.
Fences, wooden pickets that had no hope of preventing ingress or egress, surrounded the main steed pens. In most of the pens, horses and oxen grazed under the watchful eye of those on guard duty. The muster point was not by these pens. It was by the pen at the far edge. The pen that did not hold hooved animals.
