===== Spanish–American War =====
Although the US Army in the years following the Civil War lacked standing organization at the corps and division levels, it moved swiftly to adopt these during the mobilization for the Spanish–American War in the spring of 1898. On 7 May, General Order 36 called for the establishment of seven "army corps" (repeating the nomenclature of the Civil War); an eighth was authorized later that month.<ref name=HistMilMob>{{cite book|last1=Kreidberg|first1=Marvin|last2=Henry|first2=Morton|title=History of Military Mobilization|date=November 1955|publisher=Department of the Army|location=Washington, DC|pages=144–145|url=http://www.history.army.mil/html/books/104/104-10/CMH_Pub_104-10.pdf|access-date=30 July 2014|archive-date=8 August 2014|archive-url=https://web.archive.org/web/20140808052221/http://www.history.army.mil/html/books/104/104-10/CMH_Pub_104-10.pdf|url-status=dead}}</ref> Two of these saw action as a unit: the Fifth in Cuba and the Eighth in the Philippines; elements of the [[First Army Corps (Spanish–American War)|First]], [[Fourth Army Corps (Spanish–American War)|Fourth]], and [[Seventh Army Corps (Spanish–American War)|Seventh]] made up the invasion force for Puerto Rico (the Second, [[Third Army Corps (Spanish–American War)|Third]], and Seventh provided replacements and occupation troops in Cuba, while the [[Sixth Army Corps (Spanish–American War)|Sixth]] was never organized). The corps headquarters were disbanded during the months following the signing of the peace treaty (with the exception of the Eighth Army Corps, which remained active until 1900 due to the eruption of the [[Philippine–American War]]), and like the corps of the Civil War, their lineage ends at that point.
