Henry Pinckney McCain
United States general (1861–1941)
Henry Pinckney McCain (January 23, 1861 – July 25, 1941) was an American military officer who was Adjutant General of the United States Army from 1914 to 1918. He held the rank of Major General.
Early life
McCain was born in Carroll County, Mississippi, on January 23, 1861, the son of Mr. and Mrs. W. A. McCain. He was born during the brief period of time between Mississippi's secession from the United States and its joining the Confederate States of America shortly before the beginning of the American Civil War. McCain's relatives included William A. McCain (1878–1960) and John S. McCain Sr., who were his nephews.
He graduated, 20th in a class of 37, from the United States Military Academy (USMA) at West Point, New York, in June 1885. Among his classmates there included several men who would later rise to the rank of brigadier general or higher in their military careers, such as Joseph E. Kuhn, Charles H. Muir, John D. Barrette, Robert A. Brown, John M. Carson, Willard A. Holbrook, Robert Michie, Robert L. Bullard, Daniel B. Devore, Beaumont B. Buck, and William F. Martin. Upon graduating, he was commissioned a second lieutenant in the 3rd U.S. Infantry Regiment (The Old Guard) at Fort Shaw, Montana.

Why this record matters
“Henry Pinckney McCain” is worth following because a concise public description often conceals a longer documentary argument. Here, Henry, Pinckney and McCain provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 7, 2026. The linked authority identifier is Q2391056. VIAF identifies the subject as 29224266. The Library of Congress control number is no2003073506. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1861, 1941, 1914 and 1918.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
