The Blood of Baisakhi: The Forgotten Fire of Udham Singh is a powerful historical narrative that brings to light the long-ignored legacy of one of India's most fearless revolutionaries-Udham Singh. Set against the backdrop of the Jallianwala Bagh massacre, British colonial cruelty, and India's fractured caste and political landscape, this book is both a biography and a bold social commentary. With rich detail and insight, author Mayankaditya Lohiya dives deep into Singh's life-his pain, exile, defiance, and ultimate act of vengeance in Caxton Hall. From revolutionary Europe to British prisons, from caste politics to lost legacies, this book tells a story India has not fully acknowledged. Why has Udham Singh remained in the shadows of freedom history? Was it caste? Politics? Or silence by design? Meticulously researched and passionately written, this book challenges narratives and asks uncomfortable questions-making it essential reading for anyone who believes history is more than just names in textbooks.
