Pieter Bakker Pieter Bakker served the Admiralty of the Noorderkwartier. In August and September 1672, he commanded the small frigate, the Mercurius, 24 guns. In early 1653, Pieter Bakker commanded the Jupiter, 42 guns. I have some contradictory information about what happened after that. George Legge, the captain of the English 2nd Rate Royal Katherine said in his log that he captured the Jupiter of Enkhuizen, whose captain was Pieter Bakker, and which carried 50 guns and had a crew of 150 men. I have information that Pieter Bakker commanded the Jupiter in May 1673, at the Schooneveld battles and in August 1673, at the Battle of the Texel. In April 1674, he commanded the Jupiter, presumably at Martinique, with De Ruyter.
