The proposed expansion assumes the Cornish polity is the most organized surviving group in Britain. Its navy would project power while carrying the supplies needed to extend control around the island. Expansion would secure access to resources and materials absent from the initial territory. Other communities would face a choice between joining the polity and being forced into it. That coercive assumption is part of the scenario's account of how maritime logistics supports industrial recovery.
