Wilmington serves as the industrial and transit anchor of this 1919 military survey, where the Christiana River and Brandywine River converge before meeting the Delaware River. The map highlights a critical defensive and maritime corridor, dominated by the strategic presence of Fort Delaware on Pea Patch Is., flanked by Fort Dupont and Fort Mott. These coastal fortifications guarded the river approaches during a period of intense rail and canal expansion.
