During the middle decade of the 16th century a new type of sailing vessel emerged, designed to carry the wealth of the Americas to Spain. This was the galleon, and over the next century these vessels would serve Spain well as treasure ships and warships, becoming a symbol of Spanish power and wealth during the period. The development and construction of the Spanish galleon are discussed in this book, and the ordnance and crewing needed to produce and maintain these stately vessels is covered. The author also examines the role of the galleon as a treasure ship, and describes how these ships were manned and fought in action.
