Launched in 1914, two years after the ill-fated maiden voyage of her sister ship, RMS Titanic, the Britannic was intended to be superior to her tragic twin in every way. But soon after her launch war intervened and in 1915 she was requisitioned as a hospital ship. Just one year later, while on her way to collect troops wounded in the First World War's Balkans campaign, she fell victim to a mine laid by a German U-boat and tragically sank in the middle of the Aegean Sea. There her wreck lay, at a depth of 400 feet, until it was discovered 59 years later by legendary explorer Jacques Cousteau. Since then a succession of expeditions, including one by Robert Ballard who discovered the wreck of the Titanic, have uncovered more about the Britannic and life on-board ship than anyone could have hoped for. In 1996 the wreck was bought by maritime historian and author of this book, Simon Mills. This book tells the complete story of the Britannic: her construction, launch and life, her fateful last voyage, her loss to a German mine, and the historical findings resulting from the exploration of the well-preserved wreck over a period of forty years. Fully illustrated with historical photos and diagrams, and scans, sonar images and stunning photographs of the wreck and the expeditions, the book will be an essential addition to the bookshelves of anyone with an interest in maritime history, First World War history, and all those interested in diving and maritime exploration. Although much has been written on the exploration of the Titanic, to date there is nothing substantial on the similar work carried out on her sister ship. Until now.
