The Meuse-Argonne area was the setting of the largest American military action fought up to that time, a 1918 offensive intended to cut German rail lines at Sedan. Its importance lay not only in the scale of the operation but in the difficult passage through which the American forces had to move: a narrow road network, rain-soaked ground, and exposed positions near the German lines turned the approach itself into a test of endurance.

Setting and Strategic Importance

The American sector extended for twenty-four miles from the Meuse River, north of Verdun, to the Argonne Forest. As part of a much larger assault planned along the Western Front from Verdun to the sea, the operation sought to sever the German rail lines at Sedan. The Meuse-Argonne area thus joined a defined military objective to a broad, difficult front: success depended on bringing a huge force and its supplies through the region and into position without alerting the Germans.

The scale of that movement was unprecedented for the United States. Fifteen divisions—about 600,000 men—advanced with nearly 3,000 artillery pieces, trucks, tanks, supply wagons, and more than 90,000 horses. The movement relied on only three roads, often shared in opposing directions with French troops being relieved. Traffic congestion and poor discipline slowed the columns; movement had to take place under cover of darkness, and rain turned the roads to mud. Horses collapsed under the strain, while artillerymen walked beside their guns and were ordered not to lean on the caissons, even when exhaustion made the temptation difficult to resist.

The Approach to the Front

After the sudden American victory at Saint-Mihiel, orders redirected the 129th Regiment toward the Argonne. The march began on the night of September 16 in bright moonlight and continued through the night and into the day, with only brief rests. Harry S. Truman later described the repeated cycle of marching, sleeping for a few hours, and setting out again. His battery’s journey illustrates how the area’s approach roads could become a struggle in their own right: the column had to keep moving among trucks and other batteries, at times trotting or galloping to prevent vehicles from cutting through it, while rain made the road slick.

The nearly 100-mile forced march nevertheless brought the troops to their assigned positions on schedule. The 129th’s position was Hill 290, a gradual slope about half a mile from Neuvilly, a crossroads village largely reduced to a ruined stone church. Truman’s Battery D reached a clump of saplings near a wood at 3:00 a.m. in darkness and rain. The men and horses were exhausted; getting the four guns into place by daylight required twelve horses to each gun and every man pushing. Across the open no-man’s-land stood the German strongpoint at Boureuilles.

Battlefield and Campaign

The days before the assault transformed the immediate landscape into a firing position. Trenches were dug, ammunition stacked, and trees cleared to open a field of fire. German shells periodically passed overhead. One night, several struck the exact spot where Truman had slept on the first morning; he had moved before they hit. The battery’s orders called for 1,000 rounds an hour, with an initial bombardment aimed at barbed-wire entanglements before a rolling barrage accompanied the infantry advance.

The campaign did not deliver the swift victory expected after Saint-Mihiel. Sedan was ultimately taken, but the 47 days of fighting brought 117,000 American casualties. Infantry losses were particularly severe: casualties in the 35th Infantry Division reached as high as 50 percent, and wounded filled dressing stations and ambulances. The battle became associated both with the trapped unit known as the Lost Battalion, which suffered nearly 70 percent casualties, and with Alvin York, who captured 132 Germans in a day. At Romagne Heights, the battlefield’s central military cemetery would hold 14,246 American dead, becoming the largest American military graveyard in Europe.

Meaning and Aftermath

For the men who served in the area, the campaign’s scale was inseparable from its physical cost. After the regiment was withdrawn to rest, Truman wrote that the battle was worse than he had expected, and credited the infantry as the heroes. His men, exhausted and worn down by the campaign, had nonetheless come to respect him as their captain. The Meuse-Argonne area remained the place where a logistical triumph—the arrival of every unit at its appointed position—met the brutal reality of a prolonged offensive and its losses.
