Book excerpt: The historian and author of The Army in British India analyzes the British Indian Army’s devastating loss to the Imperial Japanese during WWII. The defeat of 90,000 Commonwealth soldiers by 50,000 Japanese soldiers made the World War II Battle for Malaya an important encounter for both political and military reasons. British military prestige was shattered, fanning the fires of nationalism in Asia, especially in India. Japan’s successful tactics in Malaya—rapid marches, wide outflanking movement along difficult terrain, nocturnal attacks, and roadblocks—would be repeated in Burma in 1942–43. Until the Allied command evolved adequate countermeasures, Japanese soldiers remained supreme in the field. Looking beyond the failures of command, Kaushik Roy focuses on tactics of the ground battle that unfolded in Malaya between December 1941 and February 1942. His analysis includes the organization of the Indian Army—the largest portion of Commonwealth troops—and compares it to the British and Australian armies that fought side by side with Indian soldiers. Utilizing both official war office records and personal memoirs, autobiographies, and oral histories, Roy presents a comprehensive narrative of operations interwoven with tactical analysis of the Battle for Malaya.
