A definitive account of India’s decisive military response to Pakistan-backed terrorism — told by Lt Gen K.J.S. Dhillon, one of India’s most respected Army commanders. On 22 April 2025, the Baisaran Valley in Pahalgam, south Kashmir, witnessed a horrifying attack when heavily armed terrorists from the Resistance Front, a proxy of Lashkar-e-Taiba (LeT), fully sponsored by the Pakistan Army and Inter-Services Intelligence (ISI), shattered its serenity with gunfire, killing twenty-six innocent individuals and injuring several others. The victims included newlyweds, elderly parents and solo trekkers. A Hindu professor narrowly escaped death by reciting the kalma, a Christian sacrificed his life to save his family and a local Muslim was killed while saving others. This was an attempt to rupture India’s religious harmony and create widespread outrage in the country. India chose to respond to this incident, which shook not just the nation but the world, with Operation SINDOOR, showcasing its military modernization and might. The mission targeted terror camps, including the ones in Bahawalpur and Muridke, linked to Jaish-e-Mohammed and LeT, respectively, and terrorist launch pads in Pakistan-occupied Jammu and Kashmir. India’s response demonstrated military professionalism, technological maturity and diplomatic sagacity, ensuring regional stability while delivering a powerful message against Pakistan and its terror factory. This book carries minute details and a blow-by-blow account of the ‘Four-Day War’ between two hostile nuclear powers. The author underscores the intelligent use of media and social media in the battle of narratives, discusses the ‘new normal’ and emerging rules of engagement, and suggests a way forward. Offering hitherto unrevealed information, Lt Gen. ‘Tiny’ Dhillon (Retd) opens a window to Operation SINDOOR, a testament to the strength of the Indian military and the unity of India when confronted with an adverse situation. With visuals from the destroyed target areas, this book is a powerful reminder of the impact of terrorism and the enduring hope for peace and justice. Operation SINDOOR is a must-read for everyone.
