Why Sherman's March belongs in naval history

Moving a very large army through a country with too few suitable roads is the campaign's opening problem. Sherman's dispersed columns were an operational response to that constraint, with corps advancing on four and sometimes six parallel routes. Bigger armies brought more combat power, but they also required more transport, organisation, route protection, and supporting troops simply to reach a battle. Rivers and coastal access therefore made riverine warfare, amphibious assaults, and administrative landings central to the wider Civil War. This framing places a famous land campaign within an integrated movement-and-supply system.
