Start of career
During the First World War, the 3rd Cavalry conducted remount services in France for the U.S. Army, and Earnest served with the regiment until the end of the war.[4] In October 1917, he was promoted to temporary first lieutenant.[4] After the war, the 3rd Cavalry was assigned to Fort Ethan Allen, Vermont, where he served until September 1921.[4] In May 1919, his promotion to first lieutenant was made permanent, and he was promoted to captain in July 1920.[4][7] From 1921 to 1923, Earnest attended the basic officers' course at the Fort Riley, Kansas Cavalry School.[4] Following his graduation, he was enrolled as a student in the school's Advanced Equitation Course.[4] He completed this program of instruction in 1924, after which he was assigned to the Cavalry School as an instructor.[4]
From 1930 to 1932, Earnest served with the 14th Cavalry Regiment at Fort Des Moines, Iowa, first as commander of A Troop, then Machine Gun Troop, then on the regimental staff as operations officer, intelligence officer, provost marshal, and public affairs officer.[4][8][9] After Civilian Conservation Corps duty in Missouri during 1933, he was a student at the Command and General Staff College, from which he graduated in June 1934.[4][10] He then joined the 10th Cavalry Regiment at Fort Myer, Virginia, followed by assignment to the 3rd Cavalry, also at Fort Myer, and he was promoted to major in August 1935.[4][7][11] In 1936, he completed the Chemical Warfare Course at Edgewood Arsenal, Maryland.[4] After graduating, he remained at the school as an instructor in equitation.[4]
Earnest was promoted to temporary brigadier general in February 1943, and he led the 1st Tank Destroyer Brigade during its final training at Camp Claiborne, Louisiana and departure for combat in Europe.[4] After additional training in England, in August 1944, the brigade landed in France as part of Third United States Army.[4] During combat in Daoulas and Crozon, Earnest commanded an ad hoc unit, Task Force A, which included his brigade as well as artillery, armor, infantry, and air support.[4] Task Force A played a major role in capturing the Brittany peninsula from the troops of Nazi Germany, as well as capturing numerous prisoners of war.[4]
Later career
In December 1944, Earnest was appointed to command Combat Command A, 4th Armored Division.[4] During the Battle of the Bulge, his command cleared the Arlon-Bastogne Road and broke the Nazi siege of Bastogne, which effected the relief of U.S. troops that had held the town during the height of the Bulge fighting.[4] In February 1945, Earnest was appointed assistant division commander of the 90th Infantry Division, and he became the division commander as a major general in March.[4]
The 90th Division took part in fighting from the Eiffiel mountains to the Rhine river, followed by the capture of Mainz.[4] The 90th Infantry Division then crossed the Rhine and fought from the Thuringian Forest to Czechoslovakia.[4] While clearing the town of Merkers in April, the 90th Infantry Division captured the German financial reserve, including 100 tons of gold, the equivalent of millions of dollars in U.S., British, Swedish, and French currency, and additional currency from Spain, Italy, and Turkey.[4] In addition, the reserve included many looted art treasures, among them paintings by Anthony van Dyck, Rembrandt, and Pierre-Auguste Renoir.[4] On May 3, 1945, the 90th Infantry Division obtained the surrender of the 11th Panzer Division in Všeruby, Czechoslovakia.[4]
Beginning in May 1945, the 90th Infantry Division was headquartered in Weiden in der Oberpfalz as it performed post-war occupation duty in Bavaria.[4] Earnest remained in command during the occupation duty, and through December 1945, when the division returned to the United States and was inactivated.[4] After the division's inactivation, he was assigned as assistant chief of staff for operations (G-3) at the Army Ground Forces headquarters.[4] In 1947, an assessment of his wartime experience resulted in Earnest receiving constructive credit for attendance at the National War College.[4] He remained with Army Ground Forces until June 1948, when he retired.[4]

Under his direction, the 90th Division, in 47 days of continuous contact with the enemy advanced some 400 miles across major rivers, mountains and difficult terrain. General Earnest's bold decisions, based on sound tactical insight, made possible rapid thrusts which completely disorganized the enemy and attained valuable objectives with minimum loss."
