102nd Infantry Division (United States)
The 102nd Infantry Division ("Ozark") was a unit of the United States Army in World War II. The unit is currently active as the 102nd Training Division (Maneuver Support).

Interwar period
The division was constituted in the Organized Reserve on 24 June 1921, allotted to the Seventh Corps Area, and assigned to the XVII Corps, with Arkansas and Missouri as its home area. The headquarters was organized on 2 September 1921 at 3d and Olive Streets in St. Louis, and relocated in 1923 to the Old Customhouse. The HQ remained there until activated for World War II. To encourage esprit de corps, the division adopted the nickname “Ozark” after the mountainous region that ran through both home area states, and the division staff published a newsletter titled “Ozark.” The division formed rapidly and by November 1922, it was up to 95 percent strength in its complement of officers as required by its peacetime tables of organization. The designated mobilization and training station for the division was Fort Riley, KS. The HQ and staff usually trained at Fort Leavenworth, KS. The subordinate infantry regiments of the division held their summer training primarily with the 17th Infantry Regiment at Fort Leavenworth.

In the 1920s and 1930s Harry S. Truman, a lieutenant colonel in the Officers' Reserve Corps, commanded the division's 1st Battalion, 379th Field Artillery Regiment.  After promotion to colonel, Truman advanced to command of the 379th Field Artillery Regiment.

Combat chronicle
The 102nd Infantry Division, under the command of Major General Frank A. Keating, arrived on the Western Front in the European Theater of Operations (ETO) at Cherbourg, France, 23 September 1944, and, after a short period of training near Valognes, moved to the German-Netherlands border. On 26 October, elements attached to other divisions entered combat and on 3 November the division assumed responsibility for the sector from the Wurm to Waurichen. A realignment of sectors and the return of elements placed the 102nd in full control of its units for the first time, 24 November 1944, as it prepared for an attack to the Roer. The attack jumped off, 29 November, and carried the division to the river through Welz, Flossdorf, and Linnich.

After a period of aggressive patrolling along the Roer, 4–19 December, the division took over the XIII Corps sector from the Wurm River, north of the village of Wurm, to Barmen on the south, and trained for river crossing. On 23 February 1945, the 102d attacked across the Roer (Operation Grenade), advanced toward Lövenich and Erkelenz, bypassed Mönchengladbach, took Krefeld, 3 March, and reached the Rhine. During March the division was on the defensive along the Rhine, its sector extending from Homburg south to Düsseldorf. Crossing the river on 9 April on pontoon bridge, the division attacked in the Wesergebirge, meeting stiff opposition. After 3 days and nights of terrific enemy resistance Wilsede and Hessisch-Oldendorf fell, 12 April 1945, and the 102d pushed on to the Elbe, meeting little resistance. Breitenfeld fell, 15 April, and the division outposted the Elbe River, 48 miles from Berlin, its advance halted on orders. Storkau experienced fighting on the 16th, EHRA on the 21st along with Fallersleben. On 3 May 1945 the 102nd shook hands with the Russian 156th Division just outside Berlin.

On 15 April the division discovered a war crime in Gardelegen: the Isenschnibbe Barn Atrocity. About 1,200 prisoners from the Mittelbau-Dora and Hannover-Stöcken concentration camps were forced from a train into an empty barn measuring approximately a hundred by fifty feet on the outskirts of the town. The barn was then set afire, killing those inside. About 1,016 people were killed. However, two men survived, buried under a shield of dead bodies, protecting them from the gunfire and flames.  When the first soldiers arrived at the barn, the two came crawling out from under the dead and burning bodies. Major General Keating ordered that the nearby civilian population be forced to view the site and to disinter and rebury the victims in a new cemetery. After digging the graves and burying the bodies, they erected a cross or a Star of David over each grave and enclosed the site with a white fence. Today both the former crime scene and the Cemetery of Honour are parts of the Isenschnibbe Barn Memorial Gardelegen.

The division patrolled and maintained defensive positions until the end of hostilities in Europe, then moved to Gotha for occupation duty.
