Dutch Captains named Pieter de Sitter

I am not sure that I can separate Pieter Corneliszoon de Sitter from Pieter Thomaszoon de Sitter from 1667 until 1676. We know fairly definitively that Pieter Thomaszoon de Sitter was flag captain to Abraham van der Hulst at the Four Days' Battle. The Spiegel (68 guns) was Abraham van der Hulst's flagship in that battle. Abraham van der Hulst was killed in the battle. Based on Brandt's biography of De Ruyter, I have attributed all the commands to Pieter Corneliszoon de Sitter. Pieter Corneliszoon de Sitter commanded Jaarsveld (or Huis te Jaarsveld) in the Raid on Chatham and the Raid on Harwich in 1667. In May 1672, he commanded the Agatha in the Battle of Solebay. In May and June 1673, he commanded the Agatha in the Schooneveld battles. He also fought in the Battle of the Texel in August 1673. In June 1674, he commanded the Beschermer in De Ruyter's expedition to Martinique. In 1675 and 1676, he commanded the Zuiderhuis in De Ruyter's fleet sent to the Mediterranean Sea. He was killed in 1676. Sources:
