Prelude

General John Joseph Pershing head on shoulders

General John Pershing thought that a successful Allied attack in the region of St. Mihiel,

, and

would have a significant effect on the German Army. General Pershing was also aware that the area's terrain setting first dictated that the restricted rail and road communications into Verdun (restrictions that had been imposed by the German attack during the Battle of Flirey) be cleared, and that a continuation of the attack to capture the Germany railroad center at Metz would be devastating to the Germans. For this, he placed his confidence in a young First Infantry Division Major,

proper. The American First Army had been activated in August and taken over the sector of the Allied line. Pershing had to persuade Marshall Foch (the supreme Allied military commander) to permit an American attack on the salient.

Weather reports

The weather corps of Corps I Operation Order stated: "Visibility: Heavy driving wind and rain during parts of day and night. Roads: Very muddy." This would pose a challenge to the Americans when the order to advance was given. In some parts of the road, the men were almost knee-deep in mud and water. After five days of rain, the ground was nearly impassable to both the American

nests. The battlefields' terrain included the nearby premises of three villages: Vigneulles, Thiaucourt, and Hannonville-sous-les-Cotes. Their capture would accelerate the envelopment of the German divisions near St. Mihiel. The American forces planned to breach the trenches and then advance along the enemy's logistical road network. The Germans knew many details about the Allied offensive campaign coming against them. One Swiss newspaper had published the date, time, and duration of the preparatory barrage. However, the German Army stationed in the area of St. Mihiel lacked sufficient manpower, firepower and effective leadership to launch a counter-attack of its own against the Allies. With Allied offensives to the north, the Germans decided to pull out of the St. Mihiel Salient and consolidate their forces near the Hindenburg Line. The order to evacuate the area was given on 8 September. The Allied forces discovered the information on a written order to Army Group Gallwitz.

Allied tank support

Although the AEF was new to the French theater of war, it trained hard for nearly a year in preparation for fighting against the German armies. In June 1917 Pershing ordered the creation of a tank force to support the AEF's infantry. As a result, by September 1918, Lieutenant Colonel

Battle

The Saint-Mihiel offensive began on 12 September with a threefold assault on the salient. The main attack was made against the south face by two American corps. On the right was the I Corps (from right to left the 82nd, 90th, 5th, and 2nd Divisions in line with the 78th in reserve) covering a front from Pont-à-Mousson on the Moselle west toward Limey; on the left, the IV Corps (from right to left the 89th, 42d, and 1st Divisions in line with the

in reserve) extending along a front from Limey west toward Marvoisin. A secondary thrust was carried out against the west face along the heights of the Meuse, from Mouilly north to Haudimont, by the V Corps (from right to left the 26th Division, the French 15th Colonial Division, and the 8th Brigade, 4th Division in line with the rest of the 4th in reserve). A holding attack against the apex, to keep the enemy in the salient, was made by the French II Colonial Corps (from right to left the French 39th Colonial Division, the French 26th Division, and the French 2nd Cavalry Division in line). In First Army reserve were the American 35th, 80th, and 91st Divisions. The American V Corps location was at the northwestern vertices, the II French Colonial Corps at the southern apex, and the American IV and I Corps at the southeastern vertices of the salient. Furthermore, General Pershing's intent was obvious; to envelop the salient by using the main enveloping thrusts of the attack against the weak vertices. The remaining forces would then advance on a broad front toward Metz. This pincer action, by the IV and V Corps, was to drive the attack into the salient and to link the friendly forces at the French village of Vigneulles, while the II French Colonial Corps kept the remaining Germans tied down. The French II Colonial Corps were successful in the attack on the apex and entered Saint-Mihiel on 15 September 1918, taking 4000 prisoners. They then pushed into the plain of Woëvre up to Haumont-Woël-Doncourt. The Allies mobilized 1,481 aircraft to provide air superiority and close air support over the front. About 40% were American-flown in American units, the remainder were British, French, and Italian. Nine bomber squadrons of the British RAF, although provided for the battle, were not under Pershing's operational control. Defending the salient was German "Army Detachment C", consisting of eight divisions and a brigade in the line and about two divisions in reserve. Now desperately short of manpower, they had begun a step-by-step withdrawal from the salient only the day before the offensive began. Pershing's plan had tanks supporting the advancing infantry, with two tank companies interspersed into a depth of at least three lines, and a third tank company in reserve. The result of the detailed planning was an almost unopposed assault into the salient. The American I Corps reached its first day's objective before noon, and the second day's objective by late afternoon of the second. The attack went so well on 12 September that Pershing ordered a speedup in the offensive. By the morning of 13 September, the 1st Division, advancing from the east, joined up with the 26th Division, moving in from the west, and before evening all objectives in the salient had been captured. At this point, Pershing halted further advances so that American units could be withdrawn for the coming Meuse-Argonne Offensive.
