Synopsis The invention of cannons and their use in warfare added a different dimension to battles.  The fates of nations were decided by the use of cannons.  The science of gunpowder and the technology of cannons, from their introduction in the Indian subcontinent in the middle of the fifteenth century up to the premodern period, have been illustrated using Mughal miniature paintings and analysis of extant cannon pieces.  The massive and wonderful forge welded iron cannons and cast bronze cannons of medieval India have been presented, some for the first time, in this book.  The mighty cannons that established Mughal, Maratha, Sikh and Deccan powers have been described.  Indian innovations in cannon technology like shaturnal (cannons fired from back of camels), composite cannons (of inner wrought iron bore and outer bronze casting) and bans (battlefield rockets) offer sufficient proof of Indian ingenuity in science and technology.  The book draws inspiration and major material from the original publications on the subject by the author.  Written simply and profusely illustrated with the drawings and photographs, the book embodies the latest researches on the subject. It will fascinate both serious scholars and lay readers, and provide them rare glimpses into India's rich military and metallurgical heritage.
