It's personal for lots of people. For us we will attend a local war memrorial bearing the name of Wifes Grandfather having recently attended his grave in Ypres on the 100th Anniverary of his death. A late twist to our knowledge meant we were also in position of the grid reference where he was recovered in September 1919, some 200m from the start line that morning.
Using the exhumation records from the battlefield cleanup im also plotting the locations of other 120 or so who fell that morning, which i plan to include in a small booklet about that particular incident, along with trenchmaps and current pictures. Work in progress of course!
