During the Prologue, Charles remarks on his uninspired military surroundings, making observations about the architecture as an archaeologist might observe a dig site. These observations end up being rather satirical in nature:
The smoke from the cook-houses drifted away in the mist and the camp lay revealed as a planless maze of short-cuts, superimposed on the unfinished housing-scheme, as though disinterred at a much later date by a party of archaeologists.
“The Pollock diggings provide a valuable link between the citizen-slave communities of the twentieth century and the tribal anarchy which succeeded them. Here you see a people of advanced culture, capable of an elaborate draining system and the construction of permanent highways, over-run by a race of the lowest type.”
Charles imagines his surroundings at Brideshead as a kind of inverse archaeological site, satirizing wartime by referring to soldiers as a "race of the lowest type." This passage could also serve as satire of contemporary, pre-war British society, comparing Brideshead to a "citizen-slave community." Archaeological language, utilized with a twinge of irony, reveals certain truths about the inequalities of British class organization. British people are citizens, yes, but they reside within a deeply unequal country shaped by centuries of monarchical rule and peasant oppression. As landed gentry, Sebastian and his family are part of the problem.
