Divisions

Thomas A. Guglielmo's "Divisions: A New History of Racism and Resistance in America's World War II Military" offers a searching and detailed account of how the United States armed forces grappled with race during the nation's fight against fascism abroad. The irony at the heart of the book is impossible to ignore: American soldiers were sent to defeat regimes built on racial hierarchy while serving in a military that was itself rigidly segregated. Guglielmo, a historian who has written extensively on race in twentieth-century America, uses this contradiction as the organizing thread for a book that is as much about institutional policy as it is about the lived experience of the men who served.

The book draws on an impressive range of archival material, including military records, personal letters, court-martial transcripts, and newspaper accounts, to reconstruct the day-to-day realities of segregation within the ranks. Guglielmo does not treat racism in the military as a monolithic or static force. Instead, he traces how policies shifted, sometimes in response to wartime necessity, sometimes in response to protest, and sometimes simply due to the inconsistency of an enormous bureaucracy trying to manage millions of servicemen. This nuanced approach avoids the trap of presenting the military's racial policies as a simple story of unyielding prejudice; rather, it shows a system full of contradictions, exceptions, and internal debates.

One of the book's central strengths is its attention to resistance. Guglielmo is careful to highlight the ways Black soldiers, and to a lesser extent other soldiers of color, pushed back against discriminatory treatment. This resistance took many forms: formal complaints through military channels, organized protests, individual acts of defiance, and coordinated efforts with civil rights organizations back home. By foregrounding these acts of resistance, the book resists a narrative in which Black servicemen are portrayed solely as victims of policy. Instead, they emerge as active agents who challenged the structures they lived under, often at considerable personal risk.

Guglielmo also expands the scope of his study beyond the more commonly discussed Black-white racial divide. The book examines how Japanese American, Mexican American, and Native American soldiers experienced their own forms of discrimination and negotiation within the ranks. This broader lens is one of the book's more valuable contributions, as it complicates a historical narrative that has often focused narrowly on Black and white relations. By including these additional groups, Guglielmo paints a fuller picture of how the military's racial hierarchies were multifaceted and often inconsistent across different units, regions, and branches of service.

The writing itself is clear and methodical, favoring careful documentation over dramatic narrative flourishes. Readers looking for a fast-paced or heavily narrativized account of the war may find the book's pacing more academic in nature, as Guglielmo prioritizes thoroughness and evidence over storytelling techniques. This is not a criticism so much as an observation about the book's intended purpose: it functions as a serious historical study rather than a work of popular narrative history. That said, the prose remains accessible, and Guglielmo takes care to explain context and terminology in ways that do not assume prior specialized knowledge of military history or civil rights history.

The book's chronological structure helps orient readers through changes across the war years, from the early mobilization period through the fighting overseas and into the postwar period. Guglielmo pays particular attention to how wartime experiences shaped postwar civil rights activism, suggesting that the military service of these soldiers, and their firsthand encounters with both discrimination and moments of unexpected equality abroad, contributed to a broader shift in expectations about racial justice in American society.

Overall, "Divisions" is a meticulously researched contribution to the historiography of World War II and American race relations. It does not offer easy conclusions or a simplified moral arc; instead, it presents the messy, often contradictory realities of how race was negotiated within a massive military institution during a moment of national crisis. For readers interested in the intersections of military history, civil rights history, and the social history of mid-century America, this book provides a rigorous and thoughtful examination of a period whose complexities are still being understood.
