result of an error in some editions of Marco Polo's works. The expedition was to use two small ships, Heemskerck and Zeehaen. Mauritius In accordance with Visscher's directions, Tasman sailed from Batavia on 14 August 1642 and arrived at Mauritius on 5 September 1642, according to the captain's journal. The reason for this was the crew could be fed well on the island; there was plenty of fresh water and timber to repair the ships. Tasman got the assistance of the governor Adriaan van der Stel. Because of the prevailing winds, Mauritius was chosen as a turning point. After a four-week stay on the island, both ships left on 8 October using the Roaring Forties to sail east as fast as possible. (No one had gone as far as Pieter Nuyts in 1626/27.) On 7 November, snow and hail influenced the ship's council to alter course to a more north-easterly direction, with the intention of having the Solomon Islands as their destination. Tasmania On 24 November 1642, Tasman reached and sighted the west coast of Tasmania, north of Macquarie Harbour. He named his discovery Van Diemen's Land, after Antonio van Diemen, Governor-General of the Dutch East Indies. Proceeding south, Tasman skirted the southern end of Tasmania and turned north-east. He then tried to work his two ships into Adventure Bay on the east coast of South Bruny Island, but he was blown out to sea by a storm. This area he named Storm Bay. Two days later, on 1 December, Tasman anchored to the north of Cape Frederick Hendrick just north of the Forestier Peninsula. On 2 December, two ship's boats under the command of the Pilot, Major Visscher, rowed through the Marion Narrows into Blackman Bay, and then west to the outflow of Boomer Creek where they gathered some edible "greens". Tasman named the bay, Frederick Hendrik Bay, which included the present North Bay, Marion Bay and what is now Blackman Bay. (Tasman's original naming, Frederick Henrick Bay, was mistakenly transferred to its present location by Marion Dufresne in 1772). The next day, an attempt was made to land in North Bay. However, because the sea was too rough, a ship's carpenter swam through the surf and planted the Dutch flag. Tasman then claimed formal possession of the land on 3 December 1642. For two more days, he continued to follow the east coast northward to see how far
