The Gulf and Inland Waters The Navy in the Civil War. Volume 3. — Inside the Classic

Navigating the Mississippi's Strategic Knot

The excerpts show Mahan focusing on the Mississippi as a strategic spine. He details the interplay between army and navy at Vicksburg, where canals were dug and levees cut to bypass batteries. The Yazoo Pass expedition, ordered by Grant and executed by Porter's light-draught Forest Rose, illustrates the experimental, often improvised nature of river warfare. Mahan's narrative ties these engineering efforts to the larger goal of opening the river, emphasizing that success required constant adaptation to terrain and enemy fire.

Farragut's Daring Passage at Port Hudson

Mahan devotes careful attention to Farragut's run past Port Hudson. He describes how the Hartford and her consort alone reached the final trial, nearly wrecked by the current but ultimately succeeding. The passage ensured the Red River was blockaded, though the Mississippi remained contested for months. Mahan notes that Farragut, after passing, tried to signal the fleet below, fired three guns as prearranged with General Banks, and then proceeded upriver. This episode exemplifies Mahan's focus on tactical risk and its strategic payoff.

The Ellet Rams and the Cost of Initiative

Mahan recounts the fate of the rams Switzerland and Lancaster, sent downriver without Porter's full approval. The Lancaster, an old boat, was shattered by a boiler explosion; the Switzerland survived but was badly holed. Mahan notes Porter's subsequent caution to Farragut about keeping the remaining ram under close watch. The episode highlights the tension between aggressive initiative—embodied by the Ellet family—and the logistical realities of maintaining a fleet in hostile waters.

Official Reports and the Gaps They Leave

Mahan's preface is a key to his method: official reports are the backbone, but they often omit facts well known to the writer. He sought to fill these gaps by corresponding with participants, though some never replied, forcing him to rely on his own judgment. This scholarly caution pervades the excerpts, where Mahan weighs evidence and notes uncertainties. Readers should expect a narrative that distinguishes between documented events and inferred connections, especially in the earlier, less thoroughly recorded phases of the war.

Mahan's volume rewards readers who attend to his source criticism and tactical geography. The excerpts show a writer more interested in how decisions were made—and how they were later reconstructed—than in simple heroics. For those new to Civil War naval history, the preface and early chapters establish a framework of strategic logic that the later, more dramatic actions depend upon.
