Read the passage from "Children of the Wartime Evacuation.”
As a mother, I feel deeply troubled at the thought of being forced to miss out on five or six years of my sons' childhood. I'm profoundly grateful that I have never had to face that dilemma. In Operation Pied Piper, the family suffered but I feel the real losers, as in the legend, were the parents. It was as tough for many as one would expect. Although some wrote of their immense gratitude to the kindly foster parents who had loved and cared for their children, there were far more stories of mothers feeling that they had missed part of their children's lives.
