Well done, Walter! You and your colleagues have made it, but only by the skin of your teeth. The ebb and flow of the front line enables you to catch the high tide of it at Duben before it gathers you up and retreats with you. You are free at last, nestling under US Army blankets and clutching US Army K rations at an airfield near Delitzsch.
All this thanks to the self confidence and determination of the young to march out through enemy lines to freedom. This journey started with your decision to swap your identity with a soldier and hence join his work party. It has now paid off, proving that the simplest of plans are usually the best!
