This article based on David Bercuson’s keynote address at the 22nd Military History Colloquium held at the University of Waterloo in May 2011. Bercuson discusses his role in the controversy over the panel text about the Combined Bomber Offensive at the new Canadian War Museum. Arguing the the original text was not wrong, but reflected older scholarship, he concludes by observing that no serious scholar, whether a single author or a museum staff, should be saved from the age-old processes of historical review, revision and re-writing to reflect more recent research when it is more accurate.
