The book narrates the events of the 1962 war between India and China, focusing on the disastrous conflict in the Himalayan border regions. Dalvi, who was captured and held as a prisoner of war for seven months, recounts the battle from his unique perspective as a frontline commander. He describes the Indian soldiers as brave but ill-equipped, underfed, and demoralized, fighting against a well-prepared and powerful Chinese army. The narrative exposes the disconnect between the battlefield realities and the political and military leadership in Delhi, who issued confused and ill-informed orders.Dalvi traces the roots of the conflict back to the early 1950s, highlighting China’s gradual and silent territorial encroachments into Indian soil, which India failed to adequately counter due to its policy of maintaining cordial relations. He criticizes the Indian political leadership, particularly Prime Minister Jawaharlal Nehru, Defence Minister Krishna Menon, and General Brij Mohan Kaul, for their poor strategic decisions and lack of understanding of the military situation. Dalvi argues that their arrogance and ineptitude led to the unnecessary sacrifice of thousands of soldiers and the loss of around 1,200 miles of Indian territory.The book was initially banned by the Indian government upon its release in 1969 due to its harsh critique of the leadership and its sensitive content. Despite this, it remains one of the most authentic and insightful accounts of the war, valued for its straightforward, jargon-free language and emotional depth.
