The Mayflower departs from Southampton, England, carrying would-be settlers, on its first attempt to reach North America; it is forced to dock in Dartmouth when its companion ship, the Speedwell, springs a leak.

Mayflower was an English sailing ship that transported a group of English families, known today as the Pilgrims, from England to the New World in 1620. After 10 weeks at sea, Mayflower, with 102 passengers and a crew of about 30, reached what is today the United States, dropping anchor near the tip of Cape Cod, Massachusetts, on November 21 [O.S. November 11], 1620.
