At the start of the year there were 53 known veterans alive across the world. Just seven months later, if the Wikipedia listing is to be accepted, there are just 22 veterans alive. There are from the UK(6), France(2), Germany(2), US(3), Italy(6), Germany, Canada, Poland and Australia(One each).
Of the Britons, Harry Patch is the last to have fought in the trenches. At 111 Henry Allingham is the oldest living veteran.
In a few years all will have passed into memory.
