He attended the Infantry and Cavalry School in 1895, and was in the War College in 1915.
Prior to World War I Castner had already distinguished himself. While a lieutenant he participated as an explorer in the Glenn Expedition in Alaska.[3] For his services with the Tagalog Scouts in the Philippines, he was promoted to a captaincy in the Philippine Squadron of Cavalry, which commission he held until receiving a captaincy in the Regular Army. Later he served as Constructing Quartermaster in both Honolulu and in Yellowstone National Park. While he was a captain, he commanded the Second Battalion, Fourteenth Infantry and under his training that battalion set an unequaled record in known distance firing. While a major, he was Adjutant General of the District of Columbia Army National Guard, which he developed to a high state of efficiency. As colonel of the Thirty-eighth Infantry, he instilled that fighting spirit which won for his regiment fame as the "Rock of the Marne."
As brigadier general, he took command of the Ninth Infantry Brigade. In the quiet Anould and St. Die sectors, he gave the units of the brigade effective training for the big operations that were to follow. In the Battle of Saint-Mihiel, General Castner's brigade was at first in reserve with the Tenth Brigade in line. When passage of lines was made, he pushed his outpost lines up near to the Hindenburg Line. In the first phase of the Meuse-Argonne Offensive, his Brigade captured Cunel and drove the enemy from the Bois-de-la-Pultiere and the northwestern Bois-de-Foret. In the second phase of the Meuse-Argonne Offensive, Castner's brigade captured Aincreville, Clery-le-Grand, Clery-le-Petit, Bois de Babiemont, the Punchbowl, and Doulcon. Then the brigade forced the difficult crossing of the river Meuse and fighting northward captured in succession Dun-sur-Meuse, Milly-devant-Dun, Lion-devant-Dun, Cote St. Germain, Château de Charmois, Mouzay, and the Foret de Woevre.
In appreciation for his services in the Meuse-Argonne Operation, Castner was awarded the Army Distinguished Service Medal, the citation for which reads:
He was cited in the Fifth Division Orders. While his brigade formed part of the army of occupation, Castner took the course of instruction at the Army Center of Artillery Studies at Trier, Germany.[4]
Castner retired while commanding the Third Division in the Western States.
He died on July 8, 1946.[5] He was buried at San Francisco National Cemetery.
Mount Castner and the Castner Glacier, named in his honor, are both located in the area of Alaska that he explored in 1898.[6] Castner Range and Castner Range National Monument, located in El Paso, Texas, are also named in his honor.[7]
His son, Lawrence V. Castner,[8] also later became an officer in the US Army.
