KANSAS CITY, Mo. (AP) – The National World War I Museum in Kansas City is planning a wreath-laying ceremony to mark the death of the last known veteran of the Great War.

The remembrance for Florence Green will take place Wednesday on a glass bridge that overlooks a field of 9,000 silk poppies.

They represent the 9 million combatants who died in the fighting.

Green was 110 when she died Saturday in eastern England. She was serving with the Women’s Royal Air Force as a waitress when the guns fell silent in November 1918.

The museum also had a ceremony to mark the February 2011 death of Frank Buckles, the last known American World War I veteran. Museum head Brian Alexander says it’s more important than ever to keep the memory of the veterans alive.
