Logistics of U. S. Grant’s 1863 Mississippi Campaign: From the Amphibious Landing at Bruinsburg to the Siege of Vicksburg

The historiography of U. S. Grant’s 1863 Vicksburg Campaign is extensive. Numerous tactical studies dissect in detail unit movements, strategy, and the intricacies of the siege leading to the fall of Vicksburg. Much of the campaign’s logistics remain largely untreated. This study assesses the impact of environmental conditions on complex logistical operations and how those conditions constrained battle plans, dictated command decisions, and determined tactics, given the limitations of Civil War technology. Primary focus is on Grant’s land campaign from Bruinsburg Landing to the initiation of the siege of Vicksburg. A shift from a combat operations-based to a science-based paradigm synergizes battlefield weather conditions, terrain limitations, physical properties of soils traversed by an animal-dependent army on the move, and the impact of geology on trafficability and sources of potable water, offering a new understanding of what many consider the most important campaign of the Civil War.
