Constructing a conceptual framework linking physical geography with the politics of mobility, Shell presents historical examples of the secret, subversive mobilization of people and cargo across watery spaces and harsh terrain, carried by watercraft and transport animals including pigeons, mules, camels, elephants, and sled dogs. Efforts to suppress such clandestine mobilities ranged from the violent (the shooting of pigeons) to the indirect—curtailing financial support, certain kinds of social knowledge, or schemes for infrastructural development. To show how such efforts at immobilization could affect cities and urban transportation, Shell looks at the Port of New York in the early twentieth century, where potentially transformative plans for inner-city freight transportation were rejected—likely, Shell argues, due to fears of anarchist activities. The innovative argument advanced by Shell in Transportation and Revolt challenges conventional wisdom about the supposed obsolescence of transport methods that have become marginalized in the modern era.
