The thing about oral histories is that they will invariably lack a consistent tone, and rely often on the reader already knowing all the major events of the narrative; the reader takes pleasure from the tidbits, the odds'n'ends, the little details that escape the larger, known story. While this book does have occasional nuggets, most of the narrators are not particularly eloquent; making it somewhat dry going. Compiled from found material, it does not maintain any kind of narrative throughline to engage the reader.
My biggest takeaway is that it wasn't really an even fight - the invasion force was dramatically larger and superior in every possible way, and simply overwhelmed the somewhat unprepared Axis forces; that the Germans delayed the Allies in Normandy as long as they did is equal or greater heroism than the actions of the attackers.
A bloody and awful event that really isn't well documented or honored by this patchwork affair. Recommended only for diehard WWII readers.
