Douglas MacArthur Turns 70: Birthday Greetings from the Secretary of State

Today’s post was written by David Langbart, Archivist at the National Archives at College Park.

Douglas MacArthur was born on January 26, 1880.  As his 70th birthday approached, he was serving as Supreme Commander for the Allied Powers (SCAP) in occupied Japan.  In that position he had significant interaction with the Department of State.  In honor of the General’s birthday, Secretary of State Dean Acheson signed the telegram shown below.  The relationship between SCAP and the Department of State was, to put it mildly, not the best, so perhaps sending the telegram to celebrate this milestone birthday was an effort to improve connections at the policymaker level.  


Telegram from the Secretary of State to the Supreme Commander for the Allied Powers, 25 Jan 1950; 711.551/1-2550, RG 59

MacArthur responded with the following telegram:


Telegram Z-35888 from the Supreme Commander for the Allied Powers to the Secretary of State, 27 Jan 1950; 711.551/1-2750

Given the events of the next 15 months, this exchange of messages might reflect the high point in the contentious relationship between MacArthur and Acheson.  MacArthur’s actions in Korea after the Chinese intervention in the war there in late 1950 ultimately led President Truman to relieve the General of his command and led to a total rupture in the remaining professional and personal relationship between MacArthur and Acheson.  Acheson later referred to MacArthur as a “jackass” and in his memoirs referred to the damage MacArthur’s “willful insubordination and incredibly bad judgment” did to the U.S.  He further noted that his actions “diminished” the “effectiveness” of U.S. foreign policy.
