I've started this book as well. Very well written but that particular quote worries me a bit. It implies Braddock's situation was hopeless. If it was hopeless, it was primarily because he lost control of the situation. Contrast this disaster with the situation facing Bouquet at Bushy Run where his troops did not flee in disorder under similar circumstances. Instead they held their ground and managed to rout the Indians. Comparing Braddock to Frederick the Great sounds like something only a true anglophile could come up with.
Well....... Easier said than done! Standing your ground against an Indian (Native American) ambush was a lesson that still hadn't been learned over a hundred years later (and hardly a Brit in sight) i.e. Fetterman route,Custer at LBH,Perry at White Bird Canyon......to name but a few. All defeats due to ambush or the inability to hold your ground leading to panic and defeat (during all these encounters, certain individuals performed heroically, but couldn't stem the tide)
