“From Brandywine to Philadelphia” by Thomas Sullivan (1910), published in The Pennsylvania Magazine of History and Biography, is a brief interpretive article tracing the operational sequence of the Philadelphia campaign during the American Revolutionary War, from the British victory at Brandywine to the subsequent occupation of Philadelphia in 1777.
The piece focuses on the strategic movement of British forces under General Sir William Howe following the Battle of Brandywine (September 1777), emphasizing how the defeat of American forces opened the route toward Philadelphia. Sullivan outlines the logistical and tactical steps by which British troops advanced, secured key crossings, and eventually entered the city, marking one of the major turning points of the campaign.
A portion of the discussion addresses the composition of the British expeditionary force, including the integration of auxiliary German troops drawn from states such as the Electorate of Hesse. These units are presented as part of the broader coalition structure supporting British operations, particularly in garrisoning occupied territory and securing lines of communication during the advance.
The article connects Brandywine and Philadelphia as part of a continuous operational chain rather than isolated engagements, highlighting how battlefield success translated into strategic occupation. It also reflects on the implications of the British capture of Philadelphia for the Continental Congress and American political leadership.
As a short historical essay, the work is primarily synthetic, drawing on earlier military histories and documentary sources to provide a concise narrative of the campaign’s progression. It reflects early 20th-century scholarly interest in clarifying campaign sequences and situating individual battles within broader operational frameworks.
