In today’s post, we’re looking at CAL/6, the Orderbook of Admiral Sir Henry Osborn, covering the years 1747-1757. This is one volume in a series of papers collected by the Caldwell family and donated to the National Maritime Museum together.
Admiral Sir Henry Osborn served in that crucial period from approximately 1710 to not quite 1760. This book coontains copies of his orders, rather than a collection of the physical orders themselves. Many are from Osborn to the captains of various ships under his command. During this period, Osborn was in command of fleets in the Channel, Atlantic and Mediterranean. This volume actually includes orders from just immediately prior to the Battle of Cartagena (Spain), where the Royal Navy defeated the Spanish (and redeemed themselves in their own eyes for the loss of Minorca).
Unfortunately, this volume does not contain any of his orders from his time as Commodore-Governor of Newfoundland in the early 1720s. However, this is an absolutely fascinating set of documents, a critical resource for anybody researching Osborn, Royal Navy command and control practices, or the Royal Navy during the War of the Austrian Succession.
I have 130 images of this volume, including one of the spine of the volume. This is not a complete set of the entire volume, and only cover the orders up until September 1st 1748.
