I had seen that there was a pamphlet listed in Knuttel's list that contained part of Hendrick Ernst de Bertry's journal. Carl Stapel says that it is for the period of the voyage to the Shetlands in July and August 1652. Captain de Bertry commanded the hired ship
Hollandia for the Admiralty of the Maze. I am always hoping to discover more information about Dutch captains and warships in 1652 and 1653.
