A Father Prayer by General Douglas MacArthur (May 1952)

He was Chief of Staff of the United States Army during the 1930s and played a prominent role in the Pacific theater during World War II.
He received the Medal of Honor for his service in the Philippines Campaign, which made him and his father Arthur MacArthur, Jr., the first father and son to be awarded the medal.
He was one of only five men ever to rise to the rank of General of the Army in the US Army, and the only man ever to become a field marshal in the Philippine Army.

Raised in a military family in the American Old West, MacArthur was valedictorian at the West Texas Military Academy, and First Captain at the United States Military Academy at West Point, where he graduated top of the class of 1903.
During the 1914 United States occupation of Veracruz, he conducted a reconnaissance mission, for which he was nominated for the Medal of Honor. In 1917, he was promoted from major to colonel and became chief of staff of the 42nd (Rainbow) Division.
In the fighting on the Western Front during World War I, he rose to the rank of brigadier general, was again nominated for a Medal of Honor, and was awarded the Distinguished Service Cross twice and the Silver Star seven times.

From 1919 to 1922, MacArthur served as Superintendent of the U.S. Military Academy at West Point, where he attempted a series of reforms. His next assignment was in the Philippines, where in 1924 he was instrumental in quelling the Philippine Scout Mutiny. In 1925, he became the Army's youngest major general.
He served on the court martial of Brigadier General Billy Mitchell and was president of the American Olympic Committee during the 1928 Summer Olympics in Amsterdam.
In 1930, he became Chief of Staff of the United States Army. As such, he was involved in the expulsion of the Bonus Army protesters from Washington, D.C. in 1932, and the establishment and organization of the Civilian Conservation Corps.
He retired from the US Army in 1937 to become Military Advisor to the Commonwealth Government of the Philippines.

MacArthur was recalled to active duty in 1941 as commander of United States Army Forces in the Far East.
A series of disasters followed, starting with the destruction of his air forces on 8 December 1941, and the invasion of the Philippines by the Japanese. MacArthur's forces were soon compelled to withdraw to Bataan, where they held out until May 1942.
In March 1942, MacArthur, his family and his staff left nearby Corregidor Island in PT boats and escaped to Australia, where MacArthur became Supreme Commander, Southwest Pacific Area. Upon his arrival in Australia, MacArthur gave a speech in which he famously promised "I shall return" to the Philippines.
For his defense of the Philippines, MacArthur was awarded the Medal of Honor.
After more than two years of fighting in the Pacific, he fulfilled a promise to return to the Philippines.
He officially accepted Japan's surrender on 2 September 1945, aboard USS Missouri anchored in Tokyo Bay, and oversaw the occupation of Japan from 1945 to 1951.
As the effective ruler of Japan, he oversaw sweeping economic, political and social changes.
He led the United Nations Command in the Korean War until he was removed from command by President Harry S. Truman on 11 April 1951.
He later became Chairman of the Board of Remington Rand.
