Remembrance Day

Remembrance Day (also known as Poppy Day and Armistice Day) is a memorial day observed in Commonwealth countries since the end of World War I to remember the members of their armed forces who have died in the line of duty. It is observed on 11 November to recall the official end of World War I on that date in 1918; hostilities formally ended "at the 11th hour of the 11th day of the 11th month" of 1918 with the German signing of the Armistice ("at the 11th hour" refers to the passing of the 11th hour, or 11:00 a.m.)

Here from the Streatham and Croydon Rugby Club (Icons passim) is a quote to give us pause:

No matches were played during the First World War from 1914-18. With the cessation of hostilities in WW1 , in which thirty three members - one third of the membership in 1914 - gave their lives, those fortunate enough to return were eager to restart the club and play rugby again.

One third of the membership. Scale that up over a country, a continent, a world.
