Remembering D-Day by Martin W. Bowman Collins $128 Subtitled 'Personal Histories of Everyday Heroes', this collage of reminiscences about D-Day comes from the prodigious Martin W. Bowman. It's an enterprising collection of hundreds of tightly edited stories and will be of interest to those already intimate with the history of the June 6 invasion of occupied Europe 61 years ago. Bowman contributes little, apart from brief, dry introductions, to what were essentially seven air and land battles. He relies on snapshots from the participants to describe what happened. There's nothing controversial here, which is, perhaps, as it should be. However, there's no real sense of fear, horror or the incalculable loss that underscores war. Soldiers who have survived battle rarely reveal to anyone but their closest comrades what they really felt under fire. This might have been a chance to share the experience with another generation. Were they all heroes? History, always on the side of the victor, has judged them to be so. The tougher question is: What makes a hero? Remembering D-Day is too filtered to offer any help with this question, and hence limits its appeal.
