In Fierce Valor, historians Jared Frederick and Erik Dorr unveil the fuller story of Easy Company's longest-serving commander. Tested by trials of extreme training, military rivalry, and lost love, Speirs's international odyssey begins as an immigrant child in Prohibition-era Boston and continues through the bloody campaigns of France, Holland, and Germany. But 1945 did not mark an end to Speirs's military adventures. Uncovered by sharp scholarship, his lesser-known exploits in Korea, the Cold War, and embattled Laos also come to light for the first time. Packed with groundbreaking research, Fierce Valor unveils a compelling portrait of an officer defined by boldness on the battlefield and the inherent costs of war. His story serves as a telling reminder that few soldiers escape the power of their own pasts.
