Hamlin’s study opens with a blunt premise: the time has come to ask “soberly” whether every war the United States has fought “had to be, and if it had to be, why?” The introduction, by Charles F. Dole, sets the tone by grouping war with “old world evils, like slavery or witchcraft” that humanity should clear away. The book then moves chronologically through six conflicts, from the Revolutionary War to the World War, applying a consistent lens: each war is examined for its stated causes, the economic and political pressures behind it, and the gap between official rhetoric and historical evidence.
A Recurring Pattern of Abstraction
Across the excerpts, Hamlin identifies a repeated mechanism: wars arise not from clear threats but from abstract principles. The Civil War, he argues, was fought over “the status of slavery in the western territory”—an abstraction—with both sides claiming to defend the Constitution. He notes that Lincoln’s election defied the Dred Scott decision, and that the lower south seceded as “a gesture to uphold the courts and the Constitution.” The result was a conflict where “neither section understood the other” and “emotionalism” overwhelmed reason. This pattern of abstraction recurs: the War of 1812, the Mexican War, and the Spanish-American War are each presented as contests over legal or ideological claims rather than tangible national interests.
Numbers as Counter-Narrative
Hamlin frequently deploys statistics to undermine heroic narratives. In the Civil War section, he cites voting data to show that Lincoln received only 26,430 votes in the entire South, while the moderate Douglas and Unionist Bell together outpolled the pro-slavery Breckenridge. “A majority in the south opposed secession,” he writes, “but the southern states fell into the hands of the secessionists by a plurality.” He also tracks slavery’s decline: in Missouri, the slave population fell from 17.8% of the total in 1830 to 9.8% in 1860, and Kansas voted 11,300 to 1,788 against slavery in 1858. These figures are used to argue that slavery was “dying” and that war was not necessary to end it.
The Structure of a Systematic Reassessment
The book’s architecture is straightforward: an introduction by Dole, followed by seven chapters—one for each major war, plus an opening chapter on “Patriotism and Peace.” Each chapter appears to follow a similar method: state the conventional justification, then present evidence of economic motives, political maneuvering, and propaganda. The introduction frames the project as a “rapid survey and analysis” that “boldly carries over all the wars of our own United States into the broad generalization which includes the wars of other nations.” This structural repetition reinforces the argument that no American war was exceptional; all belong to the same category of preventable catastrophe.
Movement Between Scales
Hamlin moves fluidly between broad historical claims and specific, localized details. He cites Lloyd George’s remark that nations “staggered and stumbled” into World War I, then pivots to the precise number of slaves in New Mexico (twenty-two at one time). He contrasts the global abolition of slavery—Britain in 1833, Mexico in 1827, Brazil in 1888—with the American Civil War, noting that elsewhere abolition occurred “without conflict.” This technique of juxtaposing macro and micro evidence serves to isolate the American case as an outlier, suggesting that war was not an inevitable outcome of slavery but a choice shaped by political failure and inflamed public sentiment.
Readers should approach this book as a polemic grounded in historical data, not a neutral survey. Hamlin’s evidence is selective—he emphasizes economic and political factors while giving less weight to moral or humanitarian motives—but his method is transparent. The value lies in watching a coherent argument unfold across six case studies, each challenging a cherished national story. For those interested in the mechanics of war propaganda or the historiography of American exceptionalism, this remains a provocative document from the interwar peace movement.
I’ve often found that books whisper to one another across the decades. This old 1927 history, stripping away our wartime mythologies, feels like a skeptical, windswept sentinel—not unlike the quiet fortifications chronicled in English Coast Defences From Roman Times to the Early Years of the Nineteenth Century — Reading Companion. Both, in their way, simply ask what stone and steel were truly guarding.
