From Hundred Days: The Campaign That Ended World War I, by Nick Lloyd (Basic Books, 2014), Kindle Loc. 5198-5212:
Behind the lines, the news rarely provoked outright celebration. When the battery commander, Major F. J. Rice, got up that morning and was on his way to the regimental mess for breakfast, one of his men told him that ‘it was all over sir’. Orders had come in that hostilities would cease at 11 a.m. ‘All the officers took it very calmly,’ he recalled. After breakfast they managed to get their hands on a bottle of port and shared it with their NCOs. When they saw one of the sergeants walking across the gun park, they shouted out the news. The man merely halted, saluted, and said ‘very good, sir’, before continuing on, seemingly as unconcerned as ever.
The American First-Lieutenant Clair Groover of 313th Infantry Regiment – the junior officer who had survived the assault on Montfaucon – remembered how the quietness that followed the Armistice ‘got to you’. ‘It was so unreal, that it disturbed you emotionally,’ he admitted. ‘Some of the hardest officers wept. It was so unusual that you would walk around without being shot at.’ Within moments he noticed German soldiers getting up out of their positions and moving out into the open. One of them came over and told him, with tears in his eyes, that his brother had been killed the day before and that he would like permission to locate and bury the body. Groover agreed. That night ‘all the troops along the line were treated to the greatest display of fireworks ever set off. Both sides were setting off their entire pyrotechnic supply of rockets, Very candles, red, blue, green, were sparkling in the air. The first few scared you and you would flatten out on the ground, forgetting that it was all over. That night there were camp fires all along the lines.’ That was it; it was over. ‘It was the end of the shooting war.’
