For example, in the chapter on the anti-trust trial, Chernow concluded that Rockefeller had an unstoppable monopoly that needed the government to reign it in (the conventional view). Yet in the text he wrote that throughout the trial, Standard Oil's market share steadily declined and Rockefeller was unable to stem the retreat. There was no explanation of the discrepancy.
A different take on this is "Nothing Like It In The World" by Ambrose. It's about the building of the first continental railroad. Ambrose writes in it that he fully embraced the conventional view of it, but his research for the book turned everything on its head, and he came out of the experience with a very different view.
I do have copy of Chernow's tome on Hamilton, but haven't got around to reading it yet.
