Over 88 years after WWI ended there are still over 50 known veterans alive across the world. Wikipedia lists 53 veterans from the UK(7), France(8), Germany(9), US(10), Italy(10), Canada(4), Poland (3), Australia and Romania (One each).
Not all would have seen combat - at least one of the British survivors was in training in November 1918. Even so I was surprised to see so many veterans still alive so long after the war’s end. Given that there were nearly 100 alive this time last year, it will not be long before they are all gone.
