Losing Hearts and Minds explores the loss of British power and prestige in colonial Singapore and Malaya from the First World War to the Malayan Emergency. During this period, British leaders relied on a growing number of Asian, European and Eurasian allies and servicepeople, including servants, police, soldiers, and medical professionals, to maintain their empire. At the same time, British institutions and leaders continued to use racial and gender violence to wage war. As a result, those colonial subjects closest to British power frequently experienced the limits of belonging and the broken promises of imperial inclusion, hastening the end of British rule in Southeast Asia.

  From the World Wars to the Cold War, European, Indigenous, Chinese, Malay, and Indian civilians resisted or collaborated with British and Commonwealth soldiers, rebellious Indian troops, invading Japanese combatants, and communists. Historian Kate Imy tells the story of how Singapore and Malaya became sites of some of the most impactful military and anti-colonial conflicts of the twentieth century, where British military leaders repeatedly tried—but largely failed—to win the "hearts and minds" of colonial subjects.
