In 1938, Johnson attended
Infantry School at
Fort Benning. Upon graduation, he was assigned to the
28th Infantry at
Fort Niagara, New York. Requesting an overseas transfer, Johnson was reassigned to the
57th Infantry (
Philippine Scouts) at
Fort McKinley, Philippine Islands in 1940.
World War II After the
Battle of Bataan, Johnson became a prisoner of war (POW) of the Japanese on 9 April 1942. Participating in the
Bataan Death March, Johnson was eventually imprisoned at
Camp O'Donnell, Cabanatuan and
Bilibid Prison. In December 1944, the Japanese attempted to transfer Johnson and 1,600 other POWs out of the Philippines. On 14 December 1944, American fighter planes sank the Japanese ship
Ōryoku Maru, killing over 300 of the POWs. Johnson survived and was eventually transferred to Japan. Unwilling to give up their POWs to the advancing Allies, Japan again transferred Johnson. Finally ending up in
Inchon Prison Korea, Johnson was liberated by the
7th Infantry Division on 7 September 1945.
Korean War and rise to senior command After Johnson's return to the United States, his first assignment was with the Ground Forces School. In August 1946, he attended the
Command and General Staff College at
Fort Leavenworth, Kansas, where he remained as an instructor for another two years. Johnson next attended the
Armed Forces Staff College in Norfolk, Virginia, in 1949. After graduation, he was assigned as commanding officer, 3rd Battalion,
7th Infantry at
Fort Devens, Massachusetts. Johnson organized the 1st Provisional Infantry Battalion at Fort Devens and, in August 1950, he was dispatched to Korea. The battalion became the 3rd Battalion,
8th Cavalry Regiment, assigned to the
1st Cavalry Division for the defense of the
Pusan Perimeter. Still with the 1st Cavalry Division, Johnson was later promoted to command the
5th and the 8th Cavalry Regiments. In February 1951, he was reassigned as assistant chief of staff, G3 of
I Corps. Returning to the United States, Johnson was assigned to the office of the chief of the Army Field Forces,
Fort Monroe, Virginia. In 1952, he attended the
National War College. After graduation, Johnson was assigned to the office of the assistant chief of staff, G3, where he served first, as chief of Joint War Plans Branch, then as the assistant to the chief of the Plans Division, and finally as the executive officer of the assistant chief of staff. In January 1956, Johnson was assigned to duty as assistant division commander of the
8th Infantry Division at
Fort Carson, Colorado. Later in 1956, he transferred with the 8th Division to West Germany. Johnson's next assignment was as chief of staff,
Seventh Army Headquarters at
Stuttgart-Vaihingen. Then in April 1959, Johnson moved to Headquarters,
United States Army Europe as assistant chief of staff, G3. The following December, he was appointed chief of staff,
Central Army Group (CENTAG) at
NATO Headquarters concerned with planning for the employment of French, German, and American troop operations in Central Europe. Returning to the United States, Johnson was assigned as commandant, Command and General Staff College, Fort Leavenworth, Kansas. In February 1963, he became assistant deputy chief of staff for military operations (operations and plans), Department of the Army, and in July was appointed as deputy chief of staff for military operations.
Chief of Staff On 3 July 1964, Johnson was appointed the 24th
Chief of Staff of the United States Army; his reputation as an expert tactician led to him being selected over candidates with more seniority. He had told the
National Guard Association that year that "military force ... should be committed with the object beyond war in mind" and "broadly speaking, the object beyond war should be the restoration of stability with the minimum of destruction, so that society and lawful government may proceed in an atmosphere of justice and order."
Vietnam War Johnson went to Vietnam in December 1965 after the
Battle of Ia Drang. He "concluded that it had not been a victory at all and that Westmoreland's big-unit strategy was misconceived". As Johnson saw it, the communist units would always keep their casualties below what they considered a prohibitive level, and could not be swept away by US firepower. He did, however, acknowledge that the U.S. Commander in Vietnam, General
William Westmoreland, had little choice but to engage the enemy's main formations, which had to be prevented from securing base areas where they could concentrate. Johnson was instrumental in altering the focus to a counterinsurgency approach, but was frustrated at the US Congress' refusal to provide the manpower necessary for successful pacification. In his later years Johnson said it had been obvious that US national mobilization was required to win in Vietnam, and he regretted not resigning in protest at the government asking the army to fight a war without hope of ultimate victory.
Conditions for enlisted personnel As chief of staff, one of Johnson's noteworthy accomplishments was creating the office of the
Sergeant Major of the Army to improve the quality of life for enlisted personnel. He selected Sergeant Major
William O. Wooldridge to be the first to hold this post. The other services rapidly followed suit so that for decades there has been a single senior enlisted member of each. Johnson also served as acting
chairman of the Joint Chiefs of Staff for a few months in 1967 during the convalescence of General
Earle Wheeler. Johnson retired from active duty in July 1968. For three years, General Johnson headed the
Freedoms Foundation at Valley Forge and afterwards worked as a banking executive until retiring for good. ==Final years==
