At the 11th hour of the 11th  day of the 11th month, the armistice was signed which formally ended hostilities of the First World War in 1918.  Remembrance Day is an opportunity to commemorate the contribution of British and Commonwealth military and civilian servicemen and women in the two World Wars and later conflicts. Of course, the casualties that are often forgotten are those who experienced serious mental ill-health as a result of their military service, and also ordinary people caught up in traumatic events through these conflicts.
