In the dark of night, the French flagship, L'Orient, one of the most powerful warships in the world, suddenly explodes. She sinks quickly, taking an estimated $20 million in gold and silver to the bottom. How did the mighty battleship sink so quickly that night? And what happened to the lost fortune in gold and silver? Veteran divers John Chatterton and Richie Kohler plunge into Aboukir Bay--and discover that history's telling of the L'Orient's demise is wrong. Did Admiral Nelson'spin the events of that day?

  From 1526 to 1858, the Mughals, a dynasty of nomadic Asian rulers, created a massive and powerful empire covering much of India, Pakistan, and Bangladesh, passing along an appetite for territory expansion and brutality. But they were also technological innovators and builders of some of the most enduring architecture in South Asia. Through their conquests and achievements, we learn about their military innovations like composite bows, matchlock guns, rocketry, chain mail, and cannons. We explore their feats of archery on horseback and use of elephants as fearsome weapons. And we examine their culture and enduring architecture, including palaces, forts, water systems, gardens, and the Taj Mahal--a tomb that took 22 years to build in honor of the most beloved of the sultan's wives. Join us for a sweeping history of the military ambition, innovative weapons and battle strategies, material excess, architectural wonders, and cultural flowering that shaped modern India.
