William Johnston Jr.

Johnston enlisted in the Missouri Militia in 1878, and rose to sergeant in the Lafayette Guard of St. Louis before moving to Prescott, Arizona in 1881.[1] While in Arizona, he obtained a commission as a first lieutenant in the territorial militia's Prescott Rifles company, and he served until 1883.[4] From November 1881 to October 1883, he was an Army paymaster's clerk.[5]

In February 1883, Johnston was a resident of New York City when he competed for a Congressional appointment to the United States Military Academy.[6] He was selected by a panel that made a recommendation to Representative Roswell P. Flower, but was subsequently declared ineligible because he did not meet the one-year state residency requirement.[7] In July 1883, he was appointed a second lieutenant in the United States Army directly from civil life, subject to completion of an examination by a board of officers.[8] When Johnston took the competitive examination, he placed first of 96 candidates.[9] His commission in the 16th Infantry Regiment was confirmed in October.[10]

In 1887, Johnston graduated with honors from the Infantry and Cavalry School at Fort Leavenworth, Kansas.[1] While assigned to the faculty of first Western Military Academy in Alton, Illinois[11] and later Saint Louis University,[12] Johnston attended law school at Washington University in St. Louis.[13] He was a student beginning in 1894, graduated in 1897, and received his LL.B. degree.[13] Johnston was awarded the honor of Prize Essayist of his senior class.[13]

During the Spanish–American War, Johnston served with the 46th U.S. Volunteer Infantry as a major.[10] Following the conflict, Johnston was mustered out of the volunteer service and was appointed military governor of Isabela Province in the Philippine island of Luzon, a post which he held from 1901 to 1902.

During the Philippine–American War, Johnston commanded the 1st Battalion of Philippine Scouts from 1904-1906 during the campaign against the Pulajanes, for which he was awarded the Silver Star.[14] He returned to the U.S. in 1907 to attend the Army War College until 1908.[10]

William Johnston was a member of the General Staff at the United States Army War College from 1914 to 1917. Following the American entry into World War I in April 1917, he was promoted to brigadier general and assigned to command the 180th Infantry Brigade, a unit of the 90th Division. He organized and trained the brigade, which he led to France.[10] After arriving on the Western Front in August 1918, Johnston's brigade was stationed in the Toul Sector as part of I Corps,[14]

Johnston was soon assigned to command the 91st Division, taking over from Brigadier General Frederick Steinman Foltz, who had been in temporary command. Johnston was promoted to majo general, and under his command, the 91st Division took part in the St. Mihiel offensive and the Meuse–Argonne offensive, for which he was awarded both the Distinguished Service Cross[15] and Army Distinguished Service Medal,[15] and the Ypres-Lys campaign. For his leadership in the war, Johnston was awarded the French Legion of Honor (Commander) and Croix de Guerre with Palm, the Belgian Order of Leopold I (Commander) and the Victory Medal.[14]

Following the end of the First World War, Johnston and the 91st Division were demobilized. Johnston returned briefly to the Army War College's General Staff before deploying once more to Germany in 1920 as part of the American forces occupying Germany. Over the next three years, Johnston played key roles in the occupying force, as Chief of Staff of American Forces in Germany until 1921, commanding officer of the 1st Brigade until 1922 and as general liaison officer to the French Army of the Rhine until 1923.[14]

Johnston returned to the U.S. in 1923 to command the Fourth Coast Artillery District at Fort McPherson, Georgia. The following year, he assumed command of the 3rd Infantry Division, which he led until his retirement in 1925.[10]
