First, A Caveat:

I don't necessarily agree with or endorse the sentiment in this quote, but I thought it was an interesting one:

"I will come to a time in my backwards trip when November eleventh, accidentally my birthday, was a sacred day called Armistice Day. When I was a boy, and when Dwayne Hoover was a boy, all the people of all the nations which had fought in the First World War were silent during the eleventh minute of the eleventh hour of Armistice Day, which was the eleventh day of the eleventh month.

It was during that minute in nineteen hundred and eighteen, that millions upon millions of human beings stopped butchering one another. I have talked to old men who were on battlefields during that minute. They have told me in one way or another that the sudden silence was the Voice of God. So we still have among us some men who can remember when God spoke clearly to mankind.

Armistice Day has become Veterans' Day. Armistice Day was sacred. Veterans' Day is not.

So I will throw Veterans' Day over my shoulder. Armistice Day I will keep. I don't want to throw away any sacred things.

What else is sacred? Oh, Romeo and Juliet, for instance.

And all music is."

"At last eleven o'clock came - but the firing continued"

From Eyewitness To History

Armistice - The End of World War I, 1918
The final Allied push towards the German border began on October 17, 1918. As the British, French and American armies advanced, the alliance between the Central Powers began to collapse. Turkey signed an armistice at the end of October, Austria-Hungary followed on November 3.

Germany began to crumble from within. Faced with the prospect of returning to sea, the sailors of the High Seas Fleet stationed at Kiel mutinied on October 29. Within a few days, the entire city was in their control and the revolution spread throughout the country. On November 9 the Kaiser abdicated; slipping across the border into the Netherlands and exile. A German Republic was declared and peace feelers extended to the Allies. At 5 AM on the morning of November 11 an armistice was signed in a railroad car parked in a French forest near the front lines.

The terms of the agreement called for the cessation of fighting along the entire Western Front to begin at precisely 11 AM that morning. After over four years of bloody conflict, the Great War was at an end.

"...at the front there was no celebration."

Colonel Thomas Gowenlock served as an intelligence officer in the American 1st Division. He was on the front line that November morning and wrote of his experience a few years later:

"On the morning of November 11 I sat in my dugout in Le Gros Faux, which was again our division headquarters, talking to our Chief of Staff, Colonel John Greely, and Lieutenant Colonel Paul Peabody, our G-1. A signal corps officer entered and handed us the following message:

Official Radio from Paris - 6:01 A.M., Nov. 11, 1918. Marshal Foch to the Commander-in-Chief.

1. Hostilities will be stopped on the entire front beginning at 11 o'clock, November 11th (French hour).
2. The Allied troops will not go beyond the line reached at that hour on that date until further orders.
[signed]
MARSHAL FOCH
5:45 A.M.

'Well - fini la guerre!' said Colonel Greely.

'It sure looks like it,' I agreed.

'Do you know what I want to do now?' he said. 'I'd like to get on one of those little horse-drawn canal boats in southern France and lie in the sun the rest of my life.'

My watch said nine o'clock. With only two hours to go, I drove over to the bank of the Meuse River to see the finish. The shelling was heavy and, as I walked down the road, it grew steadily worse. It seemed to me that every battery in the world was trying to burn up its guns. At last eleven o'clock came - but the firing continued. The men on both sides had decided to give each other all they had-their farewell to arms. It was a very natural impulse after their years of war, but unfortunately many fell after eleven o'clock that day.

All over the world on November 11, 1918, people were celebrating, dancing in the streets, drinking champagne, hailing the armistice that meant the end of the war. But at the front there was no celebration. Many soldiers believed the Armistice only a temporary measure and that the war would soon go on. As night came, the quietness, unearthly in its penetration, began to eat into their souls. The men sat around log fires, the first they had ever had at the front. They were trying to reassure themselves that there were no enemy batteries spying on them from the next hill and no German bombing planes approaching to blast them out of existence. They talked in low tones. They were nervous.

After the long months of intense strain, of keying themselves up to the daily mortal danger, of thinking always in terms of war and the enemy, the abrupt release from it all was physical and psychological agony. Some suffered a total nervous collapse. Some, of a steadier temperament, began to hope they would someday return to home and the embrace of loved ones. Some could think only of the crude little crosses that marked the graves of their comrades. Some fell into an exhausted sleep. All were bewildered by the sudden meaninglessness of their existence as soldiers - and through their teeming memories paraded that swiftly moving cavalcade of Cantigny, Soissons, St. Mihiel, the Meuse-Argonne and Sedan.

What was to come next? They did not know - and hardly cared. Their minds were numbed by the shock of peace. The past consumed their whole consciousness. The present did not exist-and the future was inconceivable."
