Wheeler, let’s move from arrangements for the artillery to that of the infantry on the parapet.  Mahan, like his contemporaries, left the infantry on a bare parapet, with a firing step on the banquetteContinue reading “Fortification Friday: As Wheeler would say, “Loopholes are not just for blockhouses””

Last week we gave time to Junius B.
