Ah yes, Ambrose's famous work of plagerism.
Another product of his student populated "book factory". His problem centered upon his staff using another author's material without permission. Ambrose accepted responsibility and the other author was not unhappy about the publicity. By the way, the title was lifted straight from a Walt Boyne book too. Walt was amused, but not annoyed especially.
Seriously, Ambrose writes "oral" history. This type of work is much loved for it's "real feel", but is frequently loaded with historical inaccuracies. Ambrose, unfortunately, rarely makes any effort to correct these inaccuracies. Thus, he takes a lot of heat from historians. They feel he misimforms the reading public. My take is that while this is true to some extent, many people would not have read any WWII history but for Ambrose's books. So, in total weight, his work provide a greater service than the inaccuracies do a disservice. In other words, less than perfect is still much better than nothing.
I enjoyed Band of Brothers, both in book and on film.
