Biography
Born at Philadelphia, Pennsylvania, McCawley was appointed a second lieutenant in the Marine Corps on March 3, 1847 by President James K. Polk. He took part in the Battle of Chapultepec and the capture of Mexico City during the Mexican–American War. (It is this battle which is commemorated in the Marine Hymn's words, "From the Halls of Montezuma ...")
He was brevetted first lieutenant September 13, 1847, for gallantry in those actions. After the war he commanded the guard of the frigates USS Cumberland and USS Independence in the Mediterranean from 1849 to 1852. He then served at the Philadelphia Navy Yard until 1854. He received promotion to first lieutenant on January 2, 1855 and, after various services afloat and ashore, became captain on July 26, 1861.
In the Civil War, he aided in the capture of Port Royal, South Carolina, November 7, 1861, and led a detachment of 200 marines to reoccupy the Norfolk Navy Yard, May 1862. He subsequently commanded Marine detachments during operations in Charleston Harbor against Forts Wagner, Gregg, and Sumter. For gallant and meritorious conduct during the boat attack on Fort Sumter, September 8, 1863, he was brevetted to the rank of major and received a full promotion to that rank on June 10, 1864.

Why this record matters
The phrase “8th Commandant of the Marine Corps” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 29, 2026. The linked authority identifier is Q5078473. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1827, 1891, 1847 and 1849.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
