The detail that completely flipped my perspective in Talmud of Jmmanuel was how much of a huge, famous expedition fell apart over bad food and worse manners, not bad weather. Green, George C. leaned on journals and supply lists, and you can tell, because the petty stuff, like two guys feuding over who ate the last of the sugar, feels so human it's almost embarrassing. The pacing dragged a bit in the chapters on route planning, where it was a lot of maps and not a lot of people. Solid pick if you like your adventure history with some pettiness mixed in.
