Of this expedition, which owes its origin to the loss of the ship De Ridderschap van Hollandt, between the Cape of Good Hope and Batavia, in the year 1685, reports are to be found in various works, as in Witsen, Valentijn, the Historische Beschrijving der Reizen, perhaps also in some others. No coherent account, however, appears to exist, although we read in the last-mentioned work that a narrative of the voyage was published in 1701, at Amsterdam.

The project originally formed was, that the expedition should set out from Batavia, and the Directors of the Council of the Seventeen write on this understanding in their dispatch of November 10th, 1695, to the Governor-General and Council of India; but in the assembly of December 8th and 10th of that year that plan was abandoned, and it was resolved that, “for various reasons” the expedition should be undertaken from the Cape of Good Hope, under the command of William de Vlamingh, with orders to land at the islands of Tristan d'Acunha, on this side of the Cape, and also at the islands of St. Paul and Amsterdam, to examine and to survey them.

For this purpose three ships were fitted out: the frigate De Geelvinck, commodore Willem de Vlamingh; the hooker De Nijptang, Captain Gerrit Collaert; and the galiot Weseltje, Captain Cornelis de Vlamingh, son of the commodore.

“On Thursday, the 3rd of May, 1696, at one o'clock in the morning, the noble Burgomaster Hinlopen sent the Company's boat, having on board the Commander Barent Fockesz, with orders that we should put to sea at daybreak.”
