## Biography

Colonel Herbert J. Slocum was born on April 25, 1855, in Cincinnati, Ohio to Colonel Joseph Jermain Slocum (1833-?) and Sallie Hommedieu. He was an eighth generation descendant of Plymouth Colony militia commander Captain Myles Standish.
Slocum was appointed to the United States Military Academy on July 1, 1872, but left the academy shortly after failing to graduate in 1876. Nevertheless, he received a commission in the US Army shortly afterwards. Solcum was assigned to the 7th Cavalry Regiment where he rose to the rank of captain in 1896. He spent most of his early career posted in the Dakota Territory. He graduated from the Infantry and Cavalry School in 1883.
During the Spanish–American War, Slocum was commissioned as major in the Inspector General branch in May 1898 and reverted to his permanent rank of captain a year later. He served in the occupation of Cuba from 1901 to 1902 and the Philippine Insurrection from 1905 to 1906. He was stationed in the Mid-West (mostly at Fort Riley in Kansas) from 1906 to 1910. He returned to the Philippines in 1911.
In August 1912, Slocum was promoted to colonel and assigned to Fort Leavenworth in Kansas. On September 1, 1914, he took command of the 13th Cavalry Regiment at Cavalry Camp Columbus in Columbus, New Mexico. He commanded the regiment during the Battle of Columbus on March 9, 1916, where Mexican revolutionary Pancho Villa burned several buildings in Columbus, New Mexico. Although Villa's forces were successful in capturing 300 rifles and shotguns, 80 horses, and 30 mules it came at the cost of at least 70 of his men being killed compared with American casualties of 8 soldiers and 10 civilians (including a pregnant woman) killed. Slocum was exonerated for his failure to prevent the attack by a board of inquiry led by United States Secretary of War Newton Diehl Baker, Jr.
Solcum remained on active duty with the Army through World War I and retired from the Army when he reached the mandatory retirement age of 64 on April 25, 1919.
Colonel Slocum died on March 29, 1928, in Washington, DC and is buried in Arlington National Cemetery. His estate was valued at over 3 million dollars.
