Erik rounded the southern tip of the island, later known as [[Cape Farewell, Greenland|Cape Farewell]], and sailed up the western coast. Eventually, Erik reached a part of the coast that, for the most part, seemed ice-free and consequently had conditions—similar to those of Iceland—that promised growth and future prosperity.<ref>{{Cite book|url=https://books.google.com/books?id=OlxphYHf874C&q=Erik+Thorvaldsson%2C+ice-free+coast&pg=PA18|title=In the Hands of a Child: Project Pack Explorers of the World|publisher=In the Hands of a Child|language=en|access-date=2 October 2020|archive-date=23 April 2023|archive-url=https://web.archive.org/web/20230423123102/https://books.google.com/books?id=OlxphYHf874C&q=Erik+Thorvaldsson%2C+ice-free+coast&pg=PA18|url-status=live}}</ref> According to the ''[[Saga of Erik the Red]]'', Erik spent his three years of exile exploring this land.

Erik's salesmanship of Greenland proved successful as after spending the winter in Iceland, Erik returned to Greenland in the summer of 985 with a large number of colonists.

Eventually, a [[Ivittuut|Middle Settlement]] grew, but many suggest it formed part of the Western Settlement. The Eastern and Western Settlements, both established on the southwest coast, proved the only two areas suitable for farming. During the summers, when the weather was more favorable to travel, each settlement would send an army of men to hunt in [[Disko Bay]] above the [[Arctic Circle]] for food and other valuable commodities such as seals (used for rope), [[ivory]] from [[walrus]] tusks, and [[Cetacean stranding|beached whales]].<ref>{{Cite book|last=Delgado|first=James|url=https://books.google.com/books?id=xip6x68efLoC&q=Erik+Thorvaldsson%2C+summers+hunting+disko+bay&pg=PA16|title=Across the Top of the World: The Quest for the Northwest Passage|date=2009|publisher=D & M Publishers|isbn=978-1-926706-53-5|language=en|access-date=2 October 2020|archive-date=23 April 2023|archive-url=https://web.archive.org/web/20230423123231/https://books.google.com/books?id=xip6x68efLoC&q=Erik+Thorvaldsson%2C+summers+hunting+disko+bay&pg=PA16|url-status=live}}</ref> [[File:Brattachurch.jpg|thumb|21st-century reproduction of Þjódhild's church, with [[Tunulliarfik Fjord|Eriksfjord]] in the background.

The settlement flourished, growing to 5,000 inhabitants spread over a considerable area along [[Tunulliarfik Fjord|Eriksfjord]] and neighboring [[fjord]]s. Groups of [[immigrant]]s escaping overcrowding in Iceland joined the original party. However, one group of immigrants which arrived in 1002 brought with it an [[epidemic]] that ravaged the colony, killing many of its leading citizens, including Erik himself.<ref>Marc Carlson, [http://idrisi.narod.ru/mcarlson.htm History of Medieval Greenland] {{Webarchive|url=https://web.archive.org/web/20150416210928/http://idrisi.narod.ru/mcarlson.htm |date=16 April 2015 }}, 31 July 2001.

The saga of Erik the Red portrays a number of the expeditions in the Greenland saga as just one expedition led by [[Thorfinn Karlsefni]], although Erik's son Thorvald, his daughter Freydís and Karlsefni's wife Gudrid play key roles in the retelling.<ref>Smiley, Jane. ''The Sagas of the Icelanders''. New York: Penguin Group, 2000. 653–74.{{ISBN?}}</ref> Another notable difference is the location of their settlements. According to the Grœnlendinga saga, Karlsefni and the others settled in a place that is referred to only as Vinland, while in Erik the Red's saga they formed two base settlements: Straumfjǫrðr where they spent the winter and the following spring, and Hop where they later settled but ran into problems with the natives they called [[Skræling]]s, as depicted in the Greenland saga.{{citation needed|date=December 2020}} The two accounts are largely similar otherwise, both with heavy emphasis on the exploits of [[Thorfinn Karlsefni]] and his wife Gudrid.{{citation needed|date=December 2020}} ==Notes== {{Notelist}} ==References== {{Reflist}} ==External links== {{Commons category}} {{Nuttall poster|Eric the Red}} * {{cite DCB |first=T.
