John Wilson O’Daniel was born in Newark Delaware February 15, 1894. He graduated from high school at
Oxford Pennsylvania in 1912 and attended Delaware College in Newark Delaware, where he played varsity
football and earned the nickname “Mike”. .  He enlisted in the Delaware National Guard in 1913 with Company
E, 1st Delaware Infantry.  In July 19, 1916 he was mobilized, and served as a corporal and sergeant with the
First Infantry at the Mexico border in Deming New Mexico. He was honorably discharged from service on his
23rd birthday, February 15, 1917.  

After graduation from Delaware College in 1917 he was commissioned a second lieutenant of the Infantry
Reserve on August 15 at Reserve Officers Training Camp at Fort Meyer Virginia.  He received his regular
commission on October 26 and was assigned to the 11th Infantry at Camp Forrest Tennessee.  

He shipped out for overseas duty and participated in the St. Mihiel and Neuse –Argonne offensives. He was
wounded at St. Mihiel September 12, 1918.  Testifying to his endurance and aggressiveness in battle was his
nickname, “Iron Mike”, said to be a result of his actions at St. Mihiel, where he fought for twelve hours, even
though he was hit in the face by a German machine gun bullet and severely wounded. He was awarded the
Distinguished Service Cross for his actions as well as the Purple Heart.  He returned to the United States with
the 11th Infantry on September 1919 and was transferred to the 25th Infantry at Camp Stephen D. Little
Nogales Arizona.

General O’Daniel became an Infantry instructor with New Jersey National Guard at Trenton in May 1924.  In
September 1927 he entered the Infantry School at Fort Benning Georgia and was graduated in May 1928. He
was transferred in July 1928 to the 21st Infantry at Schofield Barracks, Hawaii and in January 1930 was placed
in command of the Military Police Detachment of the Hawaiian Department at Fort Schafter.  In October 1931 he
joined the 12th Infantry at Fort Howard Maryland.

In the 1930’s with the country locked in Depression, General O’Daniel undertook a series of assignments that
departed from traditional military roles. In May 1933, General O’Daniel became assistant to the Officer in
Charge of the Port of Embarkation at New York City for the Pilgrimage of War Mother and Widows. From
September to November 1933, he was on Civilian Conservation Corps duty at Smokemont, North Carolina and
then was assigned to the 22nd Infantry at Fort Oglethorpe Georgia.  In July 1934 he was appointed Army
liaison officer with the Tennessee Valley Authority.  In March 1935 he became adjutant of District “D” of the
Civilian Conservation Corps at Fort McClellan, Alabama. He was named Executive Officer of District “D” in July
1935 earning advancement to Major in August, and a year later he became Professor of Military Science and
Tactics at the Academy of Richmond County at Augusta Georgia.

General O’Daniel entered the Command and Staff School at Fort Leavenworth Kansas in September and was
graduated in June 1939. He was then assigned to Fort Brady Michigan as an instructor of the Citizen’s Military
Training Camp and Officer’s Reserve Corps.  In August 1939 he became branch instructor in the Michigan
Military Area with headquarters in Detroit.

In January 1941 he became commander of the Second Battalion, 24th Infantry at Fort Benning with which he
participated in the Third Army maneuvers in Louisiana – a critical test of logistical and combat capabilities for
the later fighting in World War II.  At he onset of World War II, in December 1941 he was promoted to Colonel
and became Assistant Chief of Staff for operations of the Third Army and Director of the Junior Officers
Training Center in San Antonio, Texas.  In June 1942 he was named Operations Officer of the Amphibious
Training Center at Camp Edwards Massachusetts.

In July 1942 General O’Daniel was transferred to Allied Force Headquarters in Europe as Commander of the
American Invasion Training School in the British Isles.  In September 1942 he assumed command of the 168th
Infantry in the North African theater and led that unit on November 8-9 in the capture of Algiers. He was also
rewarded with his first star on the 20th of November.  In December 1942, he was assigned to organize the Fifth
Army Invasion Training Center in Africa which trained the forces for the landings in Sicily and Salerno.

General O’Daniel in June 1943 was named Deputy Commander of the Third Infantry with whom he landed in
Sicily. On July 24 1943 he returned to Algiers and was attached to the 36th Division for the Salerno landings.  
Although not required to do so, he chose to land with the troops at Salerno.  He became officer in charge of
amphibious operations for the Fifth Army on October 1, 1943 and the following month was reassigned as
Assistant Commander of the Third Infantry Division.  

He took part in the landings at Anzio in January 1944 and assumed command of the Third Infantry Division
while still on the beachhead in February 1944.  While under his command the division repelled furious German
counterattacks, finally breaking out of the beachhead encirclement and driving to Rome, where he was
rewarded with his second star.  He was also awarded the Distinguished Service Medal for his service in Italy.

Much publicized, if not completely reported, was the comment he made at a staff meeting in response to a
question from British Field Marshall Sir Harold Alexander, commander of the Allied Armies in Italy.  
“I believe
your division did not give an inch”
, said Alexander.  “Is that true?” The reply was “Not a God-Damned inch.”

He served there until August 1944 when O’Daniel and his Third Division landed at the St. Tropez Peninsula in
Southern France and drove north through the Vosges Mountains to Germany. General O’Daniel led the Third
Division up the Rhone Valley to Strasbourg, in the Colmar Pocket where it decimated German Forces in
January 1945 and when it smashed across the Siegfried Line at Zweibrucker in March 1945.  He frequently flew
over the front lines in a light airplane dropping notes to the troops below, exhorting them to advance. He led the
Division across the Rhine and participated in the capture of the Nazi citadel at Nurenburg on April 20, 1945
after ruthless house to house fighting.  General O’Daniel hoisted his flag over Adolph Hitler Square in the
center of the city and paid a rousing tribute to the exhausted infantrymen around him for having “driven the
hun” from one of the last remaining Nazi strongholds.

Just before noon on April 20, 1945-Adolf Hitler's birthday-the 2d Battalion of the 30th reached the Adolf Hitler
Platz in the center of the town after taking its ground in a building-to-building fight. The street markers in the
square were replaced by others bearing the name "Eiserner Michael Platz" (Iron Mike Square) in honor of the
3d Division's Commanding General Maj. Gen. John W. O’Daniel who was known to his intimate friends and to
thousands of Marnemen as "Iron Mike."

At 1830, in the battered Adolf Hitler Platz, a rifle platoon from each regiment, as well as tanks, TDs, and Flak
wagons, stood in silent array. Old Glory ascended an improvised flagpole and the band played the National
Anthem. Maj. Gen. John W. O’Daniel then spoke.

"Again the 3d Division has taken its objective," he said. "We are standing at the site of the stronghold of Nazi
resistance in our zone. Through your feats of arms, you have smashed fifty heavy antiaircraft guns, captured
four thousand prisoners, and driven the Hun from every house and every castle and bunker in our part of
Nurnberg.  I congratulate you upon your superior performance. . .

The band broke into "Dogface Soldier." A few bewildered civilians contemplated the red, white, and blue banner
flying at half-mast in mourning for President Franklin Delano Roosevelt.

The Third Infantry went on to conquer Augsburg, Munich, and Salzburg. It ended the war with the capture of
Berchtesgaden, Hitler’s mountain stronghold in May 1945.  Representatives of German Field Marshall
Kesserling surrendered to him and he turned them over to General Jacob L. Devers near Munich on May 5,
1945.  One of O’Daniel’s proudest trophies from the war was a pair of Hermann Goering’s trousers. He called
them “a lot of pants”.  At war’s end it was reported that O’Daniel’s “Rock of the Marne” Third Division had been
awarded one fourth of all Medals of Honor presented during the war for its feats in North Africa, Sicily, Italy,
France and Germany.

In July 1945, General O’Daniel was assigned temporary duty with Army Ground Forces Headquarters in
Washington DC. Later that month he became the commandant of the Infantry School at Fort Benning, and in
November 1946 was also appointed Commanding General there.

General O’Daniel was named Military Attaché at Moscow Russia in June 1948 and after temporary duty with the
Intelligence Division at Army headquarters, assumed that position the following September, serving until August
1950 when he was appointed Infantry Inspector in the Office of the Chief of Army Field Forces at Fort Monroe
Virginia. He once recalled that it was the only time he ever wore all of his military decorations he had received,
“to dazzle the Russians who were impressed with his medals.”  After returning from Moscow he made news
when he wrote a lengthy magazine article about his experience and was quoted as saying,
“For all its
advertised glory, Moscow first impressed me, and still does, as a vast slum.”
 The Soviet newspaper Pravda
responded by accusing him of being a spy and a liar.

In July 1951, he went to Korea to command 1st Corps, 8th Army for his last combat assignment. During his
service in Korea, he was awarded the Air Medal for meritorious achievement on flights from July 21 to August
14, 1951 and the Commendation Ribbon for meritorious achievement on July 18, 1951. General O’Daniel
gained an appreciation for the use of airpower saying
"The airlift to Korea is one of the greatest developments
of this war. It gives a commander advantages he never had in wars before."
 He pinned on his third star on
December 20th 1951.

On September 1, 1952, General O’Daniel became commanding general of U.S. Army Forces Pacific returning
once again to Fort Schafter, Hawaii.  

He capped his distinguished career when he was posted as the very first Chief of the Military Assistance
Advisory Group for Indo-China in April 1954 at the behest of President Eisenhower, leading the vanguard of
America’s involvement in Indochina. . It was a controversial appointment, in that O’Daniel was viewed by some
as not having the requisite tact and sophistication.  Eisenhower defended him and believed that his critics had
underestimated him.  “Despite his nickname and his tough exterior”, Eisenhower wrote, “General O’Daniel was
a man of great ability and tact”.  He quickly became involved in Vietnamese affairs even before the French were
defeated.  He had been chosen for the assignment largely on the basis of his successful role in creating and
supervising the training programs which had transformed the South Korean Army into an effective fighting force
during the Korean War. Now, in the aftermath of the Geneva settlement, he and his 342-man group began
preparing for the immense task of rebuilding South Vietnam's armed forces.

He was optimistic that with American help Communism in Southeast Asia could be held at bay.  He
recommended increased aid to the French and an increased American presence. His advice was taken, and he
set out to train and equip a more competent and professional South Vietnamese military as France disengaged
from the area. Iron Mike became a forceful advocate of the U.S. commitment to Viet Nam, calling it "
a test of our
guts and our resilience."
 A monument to General O’Daniels was erected at Quang Trung, about ten miles west
of Saigon, and the site of the largest training camp in the country at the time.

General O’Daniel retired from active service on December 31, 1955.  At his retirement ceremony General
Maxwell Taylor, the U.S. Army Chief of Staff, paid a personalized tribute during a Pentagon ceremony.  
Commenting that
“Iron Mike” always gets his objective”, General Taylor told the story of how General O’Daniel
captured Berchtesgaden in May 1945.  Racing down one side of the Autobahn and finally putting his forces
across the single available bridge, General O’Daniel’s men won the spirited race to the prized objective from
the soldiers of the 101st Airborne Division.  General Taylor had been in command of the 101st at the time.
General O’Daniel was awarded a third oak leaf cluster to his Distinguished Service Medal at the ceremony.  

His decorations include the French Croix de Guerre, the British Order of the Bath, the Italian Silver Medal, the
Silver Star, the Legion of Merit, the Bronze Star, and the Purple Heart. He was given Delaware’s highest civilian
medal, the Governor’s Medal and the Conspicuous Service Cross of Delaware. He was awarded an honorary
PhD from the University of Delaware in 1956.

After returning from Vietnam and retiring, he was chairman of a civilian group called American Friends of
Vietnam, demonstrating his personal commitment to the Vietnamese people.

He attended a reunion in Newark at the University of Delaware also attended by retired Marine Lt Gen. Robert
T. Pepper, and Gen. Julian C. Smith in 1967.  O’Daniel sent his alma mater a portrait given to him by Ngo Dinh
Diem, the first president of South Vietnam. The Middletown Transcript recorded his last visit to Delaware on Nov
28 1971: “Lt. Gen. John W. "Iron Mike” O’Daniel, World War II hero, returned to Newark to settle the estate of
his aunt Miss Etta J. Wilson.”

A 1945 oil portrait of General O’Daniel by Stanley Arthurs hangs in Alumni Hall at the University of Delaware.

He died in San Diego on March 27 1975, survived by his wife Gretchen, a daughter Mrs. Ruth Snyder of Pacific
Grove California, and four grandchildren. His first wife, Ruth died in 1965. His only son, John W. O’Daniel Jr., a
paratrooper, was killed in action in World War II at Arnhem in 1944. A brother, J. Allison O’Daniel, was killed in
an air crash while serving in World War I.

Lieutenant General John Wilson (Iron Mike) O’Daniel, U.S.
Army

Lt Gen John W. “Iron Mike” O’Daniel was a native son of Newark
Delaware who went on to lead one of the most distinguished and
accomplished military careers in American history.  He was an
athlete, a teacher, a warrior, an accomplished leader, and a
distinguished diplomat.  O’Daniel was short of stature (five foot six
inches) an outspoken, doughty, jut-jawed, gravel-voiced, two-
fisted, combat leader of men through three major wars spanning a
forty year career.  His motto was, “sharpen your bayonet”. In his
memoirs, Eisenhower called him “one of our outstanding combat
soldiers”.  The press likened him to General Patton for his strong
personal opinions and his fearless demeanor, as well as his dash
and daring in moving the Third Infantry across the European
Theater of Operations.
