In any case, the various dispositions of the armies and river fleets aren't nearly so interesting as another apparent example of the author's laziness.
This chapter has a brief section relating to the film The Horse Soldiers, which in our history was produced in 1959, but in this story is produced in 1939, but more on that in a moment. The section takes place by opening with a reference to IMDB (yes, the Internet Movie Database, founded in 1990, clearly a difference of 129 years leads to this) talking about the film. The movie is referring to a story 'loosely' based on General Bufords's "Tennessee Raid" in the summer of 1863. Historian Bridget Catton relates:
"[Buford] drove through western and central Tennessee, tearing up railroads and upsetting [rebel General] Van Dorn's troop deployments before reaching US-held Nashville. The climactic battle scene at the “Palmyra Meeting House,” where the Buford character, General James “Jim” Butler (whose Tennessean antecedents are heavily played up) faces his brother John, a rebel cavalry officer, is based on the fighting at Pittsburg Landing, Tennessee, between Buford’s division and that of the rebel general Nathan Bedford-Forrest.While all well and good for an alternate history section, the authors sheer laziness in writing this section boggles the mind.
