From across the pond:  King George V announced that a two-minute silence would be observed in 1919, four days before the first anniversary of Armistice Day. The silence continues to be observed every year on the 11th hour of the 11th day of the 11th month

From the front line.   Note the reference to disbelief of the end of hostilities.

I have to work today.  We are not taking a day off for this memorial.  That’s kind of sad in a way.  Those who gave their all deserve to be remembered as we are living in the glory bought by their blood.
