Another personal experience record, but a fuller, more reasoned one than most of the eye-witness accounts of the fall of France. Two Englishmen have offered their services to a French ambulance unit in early June. They are stationed behind the Marne -- and they served through the crushing defeat of the pick of France's army. It is a record of doctors and nurses and volunteers faced with a superhuman task of aid, of stretcher load after stretcher load of wounded while hospitals are bombed, of relief stations in perpetual transit as the Germans moved in. And it is the story of those last tragic days, when the roads were blocked with Parisians and with peasants in panic. An eloquent tribute and epitaph.
