Dutch Captain: Pieter Aldertszoon

Pieter Aldertszoon served the Admiralty of the Noorderkwartier. Dr. Ballhausen says that the ship he commanded was the Burcht (24 guns and a crew of 100 men). According to Dr. Ballhausen, he fought in the Battle off Dover on 29 May 1652. He was with the fleet in June and took part in the voyage to the Shetlands in July and August. He seems to have been absent from the Battle of the Kentish Knock. He did fight in the Battle of Dungeness in December. He also fought in the Battle of Portland and was reported killed in the battle.
