Question: Operation Nordwind and Meuse-Argonne Offensive, were both at which location?
Context: The Meuse-Argonne Offensive, also known as the Maas-Argonne Offensive and the Battle of the Argonne Forest, was a major part of the final Allied offensive of World War I that stretched along the entire Western Front.  It was fought from 26 September 1918 until the Armistice of 11 November 1918, a total of 47 days.  The Meuse-Argonne Offensive was the largest in United States military history, involving 1.2 million American soldiers.  It was one of a series of Allied attacks known as the Hundred Days Offensive, which brought the war to an end.  The battle cost 28,000 German lives and 26,277 American lives.  It was the largest and bloodiest operation of World War I for the American Expeditionary Force (AEF), which was commanded by General John J. Pershing, and one of the deadliest battles in American history.  American losses were exacerbated by the inexperience of many of the troops, and tactics used during the early phases of the operation. Operation North Wind (German: "Unternehmen Nordwind" ) was the last major German offensive of World War II on the Western Front.  It began on 31 December 1944 in Alsace and Lorraine in northeastern France, and ended on 25 January. Hart Goodloe (January 31, 1875 - March 21, 1954) was a surgeon in the First World War who served at Saint-Mihiel and the Meuse-Argonne Offensive.  Hart Goodloe was born in Danville, Kentucky in 1875.  He is a graduate of University of Louisville's School of Medicine and a member of Phi Chi Medical Fraternity's Alpha Alpha-Gamma Chapter serving as Grand Presiding Senior (President) of the Grand Chapter from 1900 to 1901.  On August 13, 1917 he enlisted in the U.S. Army at age 42.  He was commissioned to the rank of major and was a surgeon in the army.  By 1918 he was sent over to France and saw action at the Battle of Saint-Mihiel and Meuse-Argonne Offensive.  He was discharged from service on March 18, 1919, and resided in St. Louis, Missouri.  His war documents were destroyed in a fire at the St. Louis archives.  He died at Veterans Hospital, Biloxi, Mississippi, on March 21, 1954 at age 79. Grace D. Banker (October 25, 1892 – September 17, 1960) was a telephone operator who served during World War I (1917–1918) as Chief Operator of mobile for the American Expeditionary Forces (AEF) in the U.S. Army Signal Corps.  She led thirty-three women telephone operators known popularity as Hello Girls.  They were assigned in New York to travel to France to operate telephone switch boards at the war front in Paris, and at Chaumont, Haute-Marne.  They also operated the telephone switch boards at First Army headquarters at Ligny-en-Barrois, about 5 mi to the south of Saint-Mihiel, and later during the Meuse-Argonne Offensive.  After her return to civilian life, Banker and her team members were treated as citizen volunteers and initially not given recognition as members of the military.  In 1919, Banker was honoured with the Distinguished Service Medal for her services with the First Army headquarters during the St. Mihiel and Meuse-Argonne Offensives, with a commendation. The Meuse-Argonne American Cemetery and Memorial is a 130.5 acre World War I cemetery in France.  It is located east of the village of Romagne-sous-Montfaucon in Meuse.  The cemetery contains the largest number of American military dead in Europe (14,246), most of whom lost their lives during the Meuse-Argonne Offensive and were buried there.  The cemetery consists of eight sections behind a large central reflection pool.  Beyond the grave sections is a chapel which is decorated with stained glass windows depicting American units' insignias.  Along the walls of the chapel area are the tablets of the missing which include the names of those soldiers who fought in the region and in northern Russia, but have no known grave.  It also includes the Montfaucon American Monument.  This cemetery is maintained by the American Battle Monuments Commission.  It is open daily to the public from 9:00 a.m. to 5:00 p.m.  The cemetery is closed January 1 and December 25, but is open on all other holidays. The 827th Tank Destroyer Battalion was a tank destroyer battalion of the United States Army active during the Second World War.  It was activated in April 1942 as a segregated African American unit, deploying to Europe at the end of 1944 and attached to 12th Armored Division.  It saw action during Operation Nordwind in January 1945, where elements of the battalion performed creditably.  However, its overall combat record was marred by severe disciplinary problems and insufficient training.  It was withdrawn in February, and assigned to rear-area duties; while it nominally remained active for the remainder of the war, it had been effectively disbanded. The Battle of Canal du Nord was part of a general Allied offensive against German positions on the Western Front during the Hundred Days Offensive of World War I.  The battle took place in the Nord-Pas-de-Calais region of France, along an incomplete portion of the Canal du Nord and on the outskirts of Cambrai between 27 September and 1 October 1918.  To avoid the risk of having extensive German reserves massed against a single Allied attack, the assault along the Canal du Nord was undertaken as part of a number of closely sequenced Allied attacks at separate points along the Western Front.  It began one day after the Meuse-Argonne Offensive, one day before an offensive in the Flanders region of Belgium and two days before the Battle of St. Quentin Canal. Operation Zahnarzt (literally "Dentist") was a plan by the Germans to eliminate the Third Army during World War II.  The plan of Operation Zahnarzt was to immediately come after Operation Nordwind.  The plan was to initiate a pincer movement to encircle and destroy the 3rd US Army. 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. Herrlisheim is a commune in the Bas-Rhin department in Grand Est in north-eastern France.  The town dates from the 8th century.  Herrlisheim was the scene of very heavy fighting during "Operation Nordwind", an offensive launched by the German Army during World War II that inflicted considerable damage to the town.
