They haven’t disappeared yet. World War I veterans, that is. The last one may have died more than two years ago, but Richard Rubin’s new volume, “The Last of the Doughboys’’ brings them back, the last few survivors of the Great War, for one more march on the parade ground of history. For a long while they were forgotten but not gone. Now, thanks to Rubin, they are not forgotten.
Rubin interviewed dozens of the last doughboys when they were between the ages of 101 and 113, no easy task — not easy to find them, not so easy to converse with them. Some were sparing of speech, reflecting spare memories. Others were fountains — overflowing fountains — of recollections.
