Having recently visited Vicksburg, MS I have been thinking a lot about cities under seige or cities whose basic componentry — the streets, buildings, ridges, hollows, defiles and valleys — have become the very syntax of warfare. People tend to forget that Philadelphia was, too, occupied like Vicksburg. And I’ve always wanted to know where the line of British redoubts constructed in 1777 were and how they fit with the protuberances of Lemon Hill, Promontory Rock, Bush Hill, etc. If I can trust the British topographer P. Nicole, then their line of works were placed north of these high grounds–in flagrant opposition to military dogma. Strong places were constructed to cover the upper and middle ferries, and at fording points in the Schuylkill River.
Maybe it’s because we’re civilians but we rarely try and rate the defensibility of our urban spaces. For others living in our city, interior spaces and other enclosed structures are seen as defensive “positions” and assessed as hard targets and safe zones. Most times, interior spaces are never as safe as they feel. Perhaps we don’t need to look at texts like these in order to imagine a militarized cityscape. For some Philadelphia “civilians”, just intellectualizing about urban space as a battlefield is a luxury.
