Domestic horse

Domestic horses were indispensable to the artillery unit’s movement and firepower, but their usefulness came at a severe cost. They hauled guns and supplies through steep, rain-soaked terrain, carried officers on the march, and were exposed to shellfire alongside the soldiers. The campaign repeatedly turns on their physical labor—and on how quickly that labor could become danger, confusion, or loss.

Training and Military Work

At Camp Doniphan, Harry S. Truman’s duties included teaching men to handle horses, an area in which he knew more than most new officers. The work belonged to a broad program of military preparation: alongside horse instruction, he led trench-digging exercises and artillery training with 3-inch guns. His ability to manage the animals was practical knowledge, not an incidental accomplishment. In a horse-drawn artillery battery, the guns could not reach their positions without teams capable of pulling them, and the officers had to coordinate men, animals, and equipment as one working unit.

That dependence persisted in France. Truman spent a day on horseback in February and concluded that he must be becoming tough because he was not tired. The episode places riding among the ordinary physical demands of his new command, while also marking a shift in his confidence: he was learning not only to endure field conditions but to direct men and animals within them. The horses were part of the daily military routine, whether carrying an officer or supplying the force that moved artillery forward.

Under Fire in the Vosges

During the battery’s first action, the horses were caught in a nighttime retreat made chaotic by rain, darkness, and fear of a German counter-barrage. After the guns fired on German batteries, the unit was supposed to move immediately, bringing the horses up from the rear and hauling the guns away before the enemy could return fire. The first sergeant responsible for the horses did not arrive for nearly half an hour. In the delay, men rushed about in the dark and struggled to put gas masks on the animals as well as on themselves.

When German shells began bursting overhead, Truman was mounted and trying to see what was happening. A shell exploded nearby; his horse was hit or slipped, went into a shell hole, and rolled on top of him, pinning him down until another officer pulled him free. Meanwhile, half the horses and two guns charged off in the darkness in the wrong direction and became mired in mud. The animals’ flight was part of a wider breakdown in control, not an isolated mishap: masks obscured faces, rain and darkness hid movement, and the battery’s transport scattered just as it needed to withdraw.

After Truman regained his breath, he brought the men back under control and led them to the base position, leaving guns too deeply mired to move by hand. Two horses were dead, and two others had to be shot. The cost is recorded plainly, alongside the damaged equipment and the exhausted march through the continuing downpour. The next dangerous task was recovering the abandoned guns. The men volunteered for it, and Truman took only the horses and personnel necessary for the work. The account makes clear that a horse was not simply interchangeable transport: each loss reduced the battery’s ability to move its guns, while every recovery effort depended on animals that remained fit to pull.

The Burden of the Advance

The scale of the Meuse-Argonne offensive magnified the same dependence. Fifteen divisions—600,000 men—moved toward the front with nearly 3,000 artillery pieces and more than 90,000 horses. Horse-drawn artillery moved more slowly than infantry and trucks, so the order of march had to be mixed to prevent the columns from breaking apart. The advance was already strained by traffic moving in both directions on only three roads. To conceal the operation from the Germans, movement had to take place under cover of darkness; rain then turned the roads to rivers of mud.

The conditions wore the horses down. Many were in such poor shape that they began dropping in their traces and had to be destroyed. The artillerymen were ordered to carry what they could, and those walking behind the guns were forbidden to hold on to the gun or caissons, so they would not add weight to the horses’ burden. Exhausted men found it difficult to obey: the same equipment that the animals dragged could offer a weary soldier a handhold. In this detail, the passage shows the campaign’s physical strain passing through the whole chain of labor, from animals pulling the artillery to people following on foot.

On September 3, as the regiment crossed steep roads in full battle dress, everyone—including the officers—walked to spare the horses. The change reversed the promise on a Kansas City recruiting sign that invited men to join the artillery and ride. In the mountains, keeping the animals alive and moving mattered more than preserving that privilege. The horses were both the means by which the battery traveled and a limit on how quickly it could travel; the route had to accommodate their capacity, while their exhaustion forced the soldiers to take on more of the burden themselves.

Moving the Guns to the Front

For the final approach to its position near the Argonne Forest, Truman stripped the battery down to the firing guns and only enough men to operate them. The horses were allowed to ride for the first time during the movement. Even so, the column had to force its way through congested roads in the rain, with trucks repeatedly cutting across its path. At its destination, the battery reached a clump of saplings at 3:00 A.M., in darkness and continuing rain, with men and horses exhausted. Only by hitching twelve horses to each gun and having every man push could the four guns be brought into position by daylight.

The horses’ work did not end when the guns were in place. The battery prepared for the offensive by digging trenches, stacking ammunition, and clearing trees for a field of fire; afterward, the 129th Field Artillery was ordered forward behind the infantry. Truman and Major Gates went ahead to look for enemy gun positions, while the guns and their teams had to cross a devastated stretch of ground. The distance to sheltering woods was only about a mile and a half, but the route was cratered, muddy, and tangled with barbed wire. The crossing took twelve hours. Men and horses pushed and hauled under nearly constant fire, as German shells struck around them and exhausted soldiers began falling asleep on their feet.

Narrative Significance

The horses appear through work, exposure, and consequence rather than through an independent account of their experience. Their story is nevertheless more than a background detail: the delayed arrival of a horse team helped turn a withdrawal into a confused escape; the animals’ flight left guns stranded; and later, exhaustion, steep roads, and shell-blasted ground dictated how the battery could move. Their losses are counted beside the equipment losses, while the surviving teams determine what the unit can attempt next.

Across the campaign, the animals’ function changes with the demands placed on them. They are subjects of instruction at Camp Doniphan, mounts during field movement, targets of panic and shellfire in the Vosges, and the indispensable pulling power behind the artillery advance. The shift to men walking in order to spare them, and the use of twelve horses plus human pushing to position each gun, make the same point from opposite directions: the battery depended on the horses, but that dependence could be maintained only by continually distributing the strain between animals, soldiers, roads, and machines.
