On the 11th 11th hour on the 11th day of the 11th month of 1918, the fighting on the Western Front stopped as the armistice came into effect.

They shall grow not old,
as we that are left grow old:
Age shall not weary them,
nor the years condemn.
At the going down of the sun
and in the morning
We will remember them.

We will remember them.
Lest we forget.
