Context_2 : 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.

Formed in France in July 1918, the group was assigned to the 1st Pursuit Wing and saw action in the final months of the war, supporting the Battle of Saint-Mihiel and the Meuse-Argonne Offensive.

Context_4 : The Korean War (in South Korean Hangul: 한국전쟁 ; Hanja: 韓國戰爭 ; RR: "Hanguk Jeonjaeng " , "Korean War"; in North Korean Chosŏn'gŭl: 조국해방전쟁 ; Hancha: 祖國解放戰爭 ; MR: "Choguk haebang chǒnjaeng " , "Fatherland Liberation War"; 25 June 1950 – 27 July 1953) was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the principal support of the United States). The war began on 25 June 1950 when North Korea invaded South Korea. The United Nations, with the United States as the principal force, came to the aid of South Korea. China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North. Context_5 : The Battle of Hoengsong was a battle during the Korean War. It took place between 11–15 February 1951. As part of the renewed Chinese assault on the UN strongholds in Korea, it was the first part of the CPVA Fourth Phase Offensive, and was fought between the Chinese and United Nations forces. The Chinese were victorious in this battle, having inflicted heavy casualties to the UNC forces in the two days of fighting. South Korean soldiers were ordered to lead the assault and the U.S. were ordered to support them, not lead the assault this time. Unfortunately, after the Chinese offensive began, retreating South Korean soldiers streamed south past U.S. support forces, allowing the Chinese to flank American positions. Soon, the Chinese owned the narrow, twisting valley north of Hoengsong and the road that ran through it, the only escape route. Hundreds of U.S. soldiers including field artillerymen, infantry, and logistics soldiers were killed by Chinese forces, resulting in one of the most lopsided defeats suffered by the U.S. military in the Korean War. Context_6 : 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. Context_7 : Grace D.
