Major hostilities of World War I were formally ended at the 11th hour of the 11th day of the 11th month of 1918 with the German signing of the Armistice.
According to the Library of Congress (from the American Memory Project), "the Allied powers signed a cease-fire agreement with Germany at Rethondes, France on November 11, 1918, bringing World War I to a close. Between the wars, November 11 was commemorated as Armistice Day in the United States, Great Britain, and France. After World War II, the holiday was recognized as a day of tribute to veterans of both world wars. Beginning in 1954, the United States designated November 11 as Veterans Day to honor veterans of all U.S. wars."
In Flanders Fields
by Colonel John McCrae
In Flanders fields the poppies blow
Between the crosses, row on row,
That mark our place; and in the sky
The larks, still bravely singing, fly
Scarce heard amid the guns below
We are the dead. Short days ago
We lived, felt dawn, saw sunset glow,
Loved, and were loved, and now we lie
In Flanders fields.
Take up our quarrel with the foe
To you from failing hands we throw
The torch; be yours to hold it high.
If ye break faith with us who die
We shall not sleep, though poppies grow
In Flanders fields.
Honoring our Veterans.
