American Expeditionary Forces: The American Expeditionary Forces (AEF) was the expeditionary force of the United States Army during World War I.  It was established on July 5, 1917, in France under the command of General John J. Pershing.  During the United States campaigns in World War I it fought alongside the French Army, British Army, and Canadian Army on the Western Front, against the German Empire.  A minority of the AEF troops also fought alongside the Italian Army in that same year, against the Austro-Hungarian Army.  The AEF helped the French Army on the Western Front during the Aisne Offensive (at the Battle of Château-Thierry (1918) and Battle of Belleau Wood) in the summer of 1918, and the AEF fought its major actions in the Battle of Saint-Mihiel and the Meuse-Argonne Offensive in the latter part of 1918.

Battle of the Canal du Nord: 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.

Meuse-Argonne Offensive: 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.

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.

Nantillois: Nantillois was almost totally destroyed during World War One.  It was occupied by the Germans for a little over 4 years, and liberated by the Americans on 28 September 1918, as part of the Meuse-Argonne Offensive which started on 26 September 1918.  Several monuments are erected to commemorate the events of 1914-1918.  The most important ones are the Nantillois German Cemetery (918 graves), the community building on the main street erected to commemorate the 315th Regiment of the 79th Division who liberated the village and the memorial fountain erected for the men of the 80th Division.  The 80th Division relieved the 79th Division on 30 September, and suffered terrible losses in the attack on the Bois des Ogons, just outside the village.

Lost Battalion (World War I): The Lost Battalion is the name given to nine companies of the United States 77th Division, roughly 554 men, isolated by German forces during World War I after an American attack in the Argonne Forest in October 1918.  Roughly 197 were killed in action and approximately 150 missing or taken prisoner before 194 remaining men were rescued.  They were led by Major Charles White Whittlesey.  On 2 October, the division quickly advanced into the Argonne, under the belief that French forces were supporting the left flank and two American units including the 92nd Division were supporting the right flank.  Unknown to Whittlesey's unit, the French advance had been stalled.  Without this knowledge, the Americans had moved beyond the rest of the Allied line and found themselves completely cut off and surrounded by German forces.  For the next six days, suffering heavy losses, the men of the division were forced to fight off several attacks by the Germans.
