Broadside: the Influence of Sea Power in History is a documentary that tells the story of an English monarch, Charles II, leading his country into the fiercest trade war in the age of sail, and his Dutch adversary, Johann de Witt, a bold and able leader, whose untiring efforts saved the young Dutch republic from a war it could not win.

The website hosts as well several interviews to XVIIth history specialists such as Jonathan Israel or Andrew Lambert, and a good number of videos and useful information about the Anglo-Dutch Wars.
