William Wallace McCammon

William Wallace McCammon was born on May 28, 1838, and became a career officer of the United States Army whose service ultimately extended from the American Civil War through the closing years of the nineteenth century. His military record is unusually long and varied, covering volunteer service in the Civil War, decades in the Regular Army on the western frontier, duty at posts including Vancouver Barracks, and renewed volunteer service during the Spanish-American War. The central act of his military career, however, took place while he was still a young First Lieutenant in the 24th Missouri Infantry during the Battle of Corinth in 1862.

McCammon entered Union service in Missouri in 1861. He initially served as a First Lieutenant in the 22nd Missouri Infantry and later transferred to the 24th Missouri Infantry. By the autumn of 1862 he was assigned to Company E of the 24th Missouri Infantry and was performing duties as provost marshal. Although the provost marshal role normally involved military police, administrative and security responsibilities, the circumstances at Corinth brought McCammon directly into the fighting.

The Second Battle of Corinth was fought at Corinth, Mississippi, on October 3 and 4, 1862. The town was strategically important because major railroad lines crossed there, making it a valuable transportation center for armies operating in the Western Theater. Confederate forces attacked the Union position in an effort to recapture Corinth, producing two days of severe fighting around the town and its defensive works.

On October 3, 1862, McCammon's company came under enemy fire and suffered heavy losses. Although he was then serving on provost marshal duty rather than exercising normal company command, he voluntarily stepped forward and assumed command of Company E during the battle. He continued leading the company under fire through the fighting of October 3 and remained in command until Confederate forces were repulsed and withdrew on the following day.

This voluntary assumption of command became the basis of McCammon's Medal of Honor. His official recognition emphasizes that he took control of his company while it was already under fire and continued exercising command despite the severe losses suffered by the unit. His conduct was therefore an act of battlefield leadership rather than a flag capture, individual assault or rescue. He accepted responsibility for a badly affected infantry company during an active engagement and remained with it through the conclusion of the Confederate attack.

Only days after the Battle of Corinth, McCammon was promoted to Captain. His Civil War career continued beyond the action for which he would later receive the Medal of Honor. During the closing stage of the war he served as an Assistant Adjutant General of Volunteers, and in March 1865 he received the brevet rank of Major of Volunteers for gallant and meritorious service during the war. It is important to distinguish this brevet recognition from his later substantive Regular Army rank. McCammon eventually did become a substantive Major in the Regular Army, but that promotion occurred decades later.

After the Civil War he was honorably mustered out of volunteer service, but his military career was far from over. In 1867 McCammon entered the Regular Army as a Second Lieutenant in the 14th U.S. Infantry. He later advanced to First Lieutenant and served for many years as a regimental adjutant. His Regular Army career placed him at a series of western posts during the period when the Army maintained garrisons across the expanding western United States.

McCammon's surviving diaries and correspondence document decades of military life between 1861 and 1902. They preserve observations about garrison duties, Army administration, officers, military politics and daily life on the frontier. His career included service connected with the Indian frontier, although no separate Indian Campaign Medal has been included in his verified ribbon rack because recipient-specific issuance evidence has not been established.

Among McCammon's later assignments was service at Vancouver Barracks in Washington. He served there with the 14th Infantry and at one point temporarily commanded the post. His normal responsibilities included command of an infantry company. Vancouver Barracks was one of the important U.S. Army installations in the Pacific Northwest, and McCammon's association with the post eventually became a lasting part of his personal history.

He continued advancing through the Regular Army and reached the rank of Captain in 1891. By then more than three decades had passed since the fighting at Corinth. His action of October 1862 had remained part of his service record, but he had not yet received the nation's highest military decoration for it.

That changed on July 9, 1896, when William Wallace McCammon was presented the Medal of Honor for his conduct at Corinth. The award came almost thirty-four years after the action. He was alive to receive it, so the decoration was not posthumous. The large gap between the action date and the presentation date is important because the project's historical medal system uses the actual issue period when selecting the correct Medal of Honor version.

McCammon's heroic action occurred on October 3, 1862, but his Medal of Honor was issued on July 9, 1896. For the VictoriaCross.ca database, the correct entry is therefore Medal of Honor 1896–1903 Army — 1896. The 1896–1903 designation refers to the historical Army Medal of Honor ribbon and design period applicable when the decoration was issued; it does not change the fact that the qualifying battlefield action occurred during the Civil War in 1862.

No separate star, clasp, bar, oak leaf cluster or other device has been verified for McCammon's Medal of Honor. His verified ribbon entry therefore remains a single Medal of Honor without an additional device. Under the project's evidence rules, this is the only decoration currently supported strongly enough for inclusion in his final published rack.

McCammon was still serving when the Spanish-American War began in 1898. During that conflict he was appointed a Major in the volunteer service and served in an Assistant Adjutant General capacity. His volunteer appointment ended later that year, after which he continued his Regular Army career. His service during the Spanish-American War demonstrates the extraordinary span of his military life: the same officer who had commanded troops under fire at Corinth in 1862 was still serving the Army during another major American war thirty-six years later.

In 1900 McCammon attained the substantive Regular Army rank of Major, confirming Major as his highest verified permanent U.S. Army rank. He served as a Major of the 6th Infantry before completing his career. His earlier brevet Major rank from the Civil War and his temporary Major appointment during the Spanish-American War should therefore not be confused with this later substantive Regular Army promotion.

McCammon retired from the United States Army on May 28, 1902, his sixty-fourth birthday. By that point his military career had encompassed volunteer Civil War service, Regular Army frontier duty, command and staff assignments, the Spanish-American War and more than four decades of association with the Army, interrupted only briefly between his volunteer and Regular Army appointments.

Several later campaign medals might appear plausible when looking only at McCammon's lengthy service history, but they have not been added to his verified medal rack. The Civil War Campaign Medal, Indian Campaign Medal, Spanish Campaign Medal and Spanish War Service Medal all require independent entitlement evidence. No sufficiently strong recipient-specific medal roll, individual issue record, named medal or equivalent evidence has been established for McCammon. Several of these decorations were also authorized only after his death. Under the project's zero-assumption standard, military service that appears eligible cannot be converted automatically into a verified medal entitlement.

William Wallace McCammon died on March 27, 1903, in Vancouver, Washington, less than a year after his retirement. He was buried at Vancouver Barracks Post Cemetery, where his grave remains associated with his status as a Medal of Honor recipient. His long connection with Vancouver Barracks made the location particularly fitting for an officer whose later military life had been closely tied to the post and the Pacific Northwest.

McCammon's final verified profile records him as William Wallace McCammon, United States Army, First Lieutenant at the time of his Medal of Honor action and Major as his highest substantive U.S. Army rank. His defining act occurred at Corinth, Mississippi, on October 3, 1862, when, while serving as provost marshal, he voluntarily assumed command of Company E, 24th Missouri Infantry under fire and continued leading the company until the Confederate attack was repulsed and the enemy withdrew the following day. For that conduct he received the Medal of Honor on July 9, 1896.

His final verified decoration for the database remains Medal of Honor 1896–1903 Army — 1896, with no verified device or clasp. The strength of McCammon's military legacy lies not only in the single act of leadership that earned the Medal of Honor, but also in the extraordinary continuity of his service. From the Civil War through frontier assignments and the Spanish-American War, he remained a professional soldier for most of his adult life, eventually retiring as a Major after more than forty years of military experience.
