Hello
A few years ago there was a display in my local Library including the following books
The Last Fighting Tommy: The Life of Harry Patch, Last Veteran of the Trenches, 1898-2009;
Kitchener's Last Volunteer: The Life of Henry Allingham, the Oldest Surviving Veteran of the Great War
The Last of the Last: The Final Survivor of the First World War
I can recommend all three, ordinary guys doing extraordinary things.
