In Leadership in War: Essential Lessons from Those Who Made History, Andrew Roberts examines the decisions, strengths, and shortcomings of some of the twentieth century’s most consequential wartime leaders. Drawing on well-known historical episodes, he explores how character, judgment, communication, and resolve shaped the course of major conflicts.

Roberts writes with clarity and enthusiasm, making complex historical events accessible without sacrificing their significance. His concise portraits of each leader are engaging and often insightful, offering useful observations on leadership under extraordinary pressure. However, the book’s broad scope means that several subjects receive only a relatively brief treatment, leaving readers who are already familiar with the history wanting a deeper analysis.
