: : What does the "D" in D-Day stand for?
: I don't know and, surprisingly, from the information on the following Web site, nobody else does either.
: From http://www.ddaymuseum.org/education/dday_education_factsheet_whatdoes.html
: This is the most frequently asked question by visitors to The
National D-Day Museum. Many people think they know the answer: designated
day, decision day, doomsday, or even death day.
: Our answer, like many answers in the field of history, is not so simple. Disagreements between military historians and etymologists about the meaning of D-Day abound.
: Here are just two explanations:
: In Stephen Ambrose's D-Day, June 6, 1944: The Climactic Battle of World War II, he writes, Time magazine reported on June 12  that "as far as the U.S. Army can determine, the first use of D for Day, H for Hour was in Field Order No. 8, of the First Army, A.E.F., issued on Sept. 20, 1918, which read, 'The First Army will attack at H-Hour on D-Day with the object of forcing the evacuation of the St. Mihiel salient.'" (p. 491) In other words, the D in D-Day merely stands for Day. This coded designation was used for the day of any important invasion or military operation. For military planners (and later historians), the days before and after a D-Day were indicated using plus and minus signs: D-4 meant four days before a D-Day, while D+7 meant seven days after a D-Day.
: In Paul Dickson's War Slang, he quotes Robert Hendrickson's Encyclopedia of Word and Phrase Origins. Many explanations have been given for the meaning of D-Day, June 6, 1944, the day the Allies invaded Normandy from England during World War II. The Army has said that it is "simply an alliteration, as in H-Hour." Others say the first D in the word also stands for "day," the term a code designation. The French maintain the D means "disembarkation," still others say "debarkation," and the more poetic insist D-Day is short for "day of decision." When someone wrote to General Eisenhower in 1964 asking for an explanation, his executive assistant Brigadier General Robert Schultz answered: "General Eisenhower asked me to respond to your letter. Be advised that any amphibious operation has a 'departed date'; therefore the shortened term 'D-Day' is used." (p.146)
: Brigadier General Schultz reminds us that the invasion of Normandy on June 6, 1944 was not the only D-Day of World War II. Every amphibious assault-those in the Pacific, in North Africa, and in Sicily and Italy-had its own D-Day. The National D-Day Museum's opening exhibition explores the history and lessons of the Normandy invasion. In 2001 a special exhibition will highlight the D-Days of the Pacific Theater, North Africa, and the Italian Campaign.
Surely it just stands for day.
