Question: What was the middle name of the General who commanded the US forces at the Battle of Fort Driant ? 

full_context: Document 1: Twelfth United States Army Group: The Twelfth United States Army Group was the largest and most powerful United States Army formation ever to take to the field. It controlled the majority of American forces on the Western Front in 1944 and 1945. It was commanded by General Omar Bradley with its headquarters established in London on 14 July 1944.
Document 2: Fortified Sector of Rohrbach: The Fortified Sector of Rohrbach ("Secteur Fortifié de Rohrbach") was the French military organization that in 1940 controlled the section of the Maginot Line in the vicinity of Bitche. The sector was bordered to the west by the Fortified Sector of the Sarre and to the east by the Fortified Sector of the Vosges. With lower priority than other sectors, the SF Rohrbach was built somewhat later than its neighbors to the east and west, and in company with positions on the extreme western end of the Maginot Line, became one of the "New Fronts." The sector contains several major "ouvrages" and was the scene of fighting in both 1940 and 1944. It was attacked in 1940 by German forces in the Battle of France. The sector was heavily engaged by German forces in mid-June 1940, with several casemates and the "petit ouvrage" Welschhof surrendering before the Second Armistice at Compiègne. The remaining positions and their garrisons finally surrendered on 27 June 1940. In 1944 German forces occupied several positions in the SF Rohrbach, forcing advancing American forces to attack them individually or to bypass them. The German Operation Nordwind offensive of early 1945 caused American forces to fall back, returning to complete the capture of the Rohrbach sector in March 1945. Following the war many positions were reactivated for use during the Cold War. Two locations are now preserved and open to the public.
Document 3: Battle of Aachen: The Battle of Aachen was a major combat action of World War II, fought by American and German forces in and around Aachen, Germany, between 2–21 October 1944. The city had been incorporated into the Siegfried Line, the main defensive network on Germany's western border; the Allies had hoped to capture it quickly and advance into the industrialized Ruhr Basin. Although most of Aachen's civilian population was evacuated before the battle began, much of the city was destroyed and both sides suffered heavy losses. It was one of the largest urban battles fought by U.S. forces in World War II, and the first city on German soil to be captured by the Allies. The battle ended with a German surrender, but their tenacious defense significantly disrupted Allied plans for the advance into Germany.
Document 4: Lorraine Campaign: Lorraine Campaign is a term used by U.S. Army historians to describe operations of the U.S. Third Army in Lorraine during World War II from September 1 through December 18, 1944. Official U.S. Army campaign names for this period and location are "Northern France" and "Rhineland". The term was popularized by the publication of a volume of the same name by the U.S. Army in 1950. As written by the volume's author:
Document 5: George S. Patton: General George Smith Patton Jr. (November 11, 1885 – December 21, 1945) was a senior officer of the United States Army who commanded the U.S. Seventh Army in the Mediterranean and European theaters of World War II, but is best known for his leadership of the U.S. Third Army in France and Germany following the Allied invasion of Normandy in June 1944.
Document 6: Battle of Fort Driant: The Battle of Fort Driant was a constituent battle in the 1944 Battle of Metz, during the Lorraine Campaign and the greater Siegfried Line Campaign. The battle was on occupied French territory between the forces of the United States Third Army under the command of General George S. Patton and the forces of Nazi Germany under General Otto von Knobelsdorff.
Document 7: Battle of Arracourt: The Battle of Arracourt was a major clash between U.S. and German armored forces near the town of Arracourt, Lorraine, France, between 18–29 September 1944, during World War II. As part of a counteroffensive against recent U.S. advances in France, the German 5th Panzer Army had as its objective the recapture of Lunéville and the elimination of the U.S. XII Corps bridgehead over the Moselle River at Dieulouard. With local superiority in troops and tanks, the Germans anticipated quick defeat of the defending Combat Command A (CCA) of the U.S. 4th Armored Division. However, due in part to poor German tactics and the terrain, the 4th Armored Division's CCA, in concert with U.S. tactical air forces, defeated two Panzer Brigades and elements of two "Panzer" divisions in a series of engagements over an eleven-day period.
Document 8: Matthew Ridgway: General Matthew Bunker Ridgway (March 3, 1895 – July 26, 1993) was the 19 Chief of Staff of the United States Army. He served with great distinction during World War II, where he was the Commanding General (CG) of the 82nd Airborne Division, leading it in action in Sicily, Italy and Normandy, before taking command of the newly formed XVIII Airborne Corps in August 1944, holding this post until the end of the war, commanding it in the Battle of the Bulge, Operation Varsity and the Western Allied invasion of Germany.
Document 9: Dwight D. Eisenhower: Dwight David "Ike" Eisenhower ( ; October 14, 1890 – March 28, 1969) was an American politician and Army general who served as the 34th President of the United States from 1953 until 1961. During World War II, he was a five-star general in the United States Army and served as Supreme Commander of the Allied Expeditionary Forces in Europe. He was responsible for planning and supervising the invasion of North Africa in Operation Torch in 1942–43 and the successful invasion of France and Germany in 1944–45 from the Western Front.
Document 10: 66th Armor Regiment: The 66th Armor Regiment is the oldest armored unit in the United States Army (see Iron Knights: the United States 66th Armored Regiment, by Maj. Gordon A. Blaker), tracing its lineage to the 301st Tank Battalion which served with distinction soon after it was formed in the First World War; the 301st trained at Camp Meade, MD, where then Cpt. Dwight D. Eisenhower was an instructor. It has often been rumored that the 301st, the parent unit of the 66th, was first commanded by Col. George S. Patton, but this appears not to have been the case; while Patton was the first officer assigned to the Tank Corps, and while the 301st Tank Battalion was the first unit formed, Patton went nearly immediately to France to train Americans attached to Allied commands. The 301st was the only American heavy tank battalion to have seen action in the war. After the war, the 301st transitioned in the Regular Army to become the 66th Infantry Regiment (Light Tanks) by way of the 16th Tank Battalion.
Document 11: Battle of Hürtgen Forest: The Battle of Hürtgen Forest (German: "Schlacht im Hürtgenwald" ) was a series of fierce battles fought from 19 September to 16 December 1944 between American and German forces on the Western Front during World War II in the Hürtgen Forest about 50 mi2 east of the Belgian–German border. It was the longest battle on German ground during World War II, and is the longest single battle the U.S. Army has ever fought.
Document 12: Martin Blumenson: Martin Blumenson (8 November 1918–15 April 2005) was an American military historian who served as a historical officer with the Third and Seventh Armies in World War II and later became a prolific author. His works included an authoritative biography of General George S. Patton.
Document 13: Sixth United States Army Group: The Sixth United States Army Group was an Allied Army Group that fought in the European Theater of Operations during World War II. Made up of field armies from both the United States Army and the French Army, it fought in France, Germany, Austria, and, briefly, Italy. Also referred to as the Southern Group of Armies, it was established in July 1944 and commanded throughout its duration by General Jacob L. Devers.
Document 14: Ouvrage Otterbiel: Ouvrage Otterbiel forms part of the Maginot Line in the Fortified Sector of Rohrbach, Sub-sector of Bitche, and is located on the "Camp de Bitche" of the French Army. It is located between "gros ouvrage" Schiesseck and "petit ouvrage" Grand Hohekirkel. Part of the Fortified Sector of Rohrbach, the "petit ouvrage" comprises four combat blocks and an entry block. Due to budget restrictions, a planned flanking infantry block was never constructed. Otterbiel saw no significant action in the Battle of France, and limited action during the 1944/45 Lorraine Campaign. It was renovated for use during the Cold War. Otterbiel is used for ammunition storage by the French Army.
Document 15: Battle of the Bulge: The Battle of the Bulge (16 December 1944 – 25 January 1945) was the last major German offensive campaign on the Western Front during World War II. It was launched through the densely forested Ardennes region of Wallonia in eastern Belgium, northeast France, and Luxembourg, towards the end of World War II. The surprise attack caught the Allied forces completely off guard. American forces bore the brunt of the attack and incurred their highest casualties of any operation during the war. The battle also severely depleted Germany's armored forces, and they were largely unable to replace them. German personnel and, later, Luftwaffe aircraft (in the concluding stages of the engagement) also sustained heavy losses.
