Many members of the Leyden Congregation departed from Leyden in late July 1620 aboard the Speedwell. These Pilgrims sailed to Southampton, England, where they met up with the Mayflower and together the two ships departed from Southampton in early-mid August, but they had to land at Dartmouth after the Speedwell sprung a leak. After a second failed attempt, many of the passengers returned to London. 102 passengers then boarded the Mayflower and with the ship's crew departed for the New World in early-mid September, arriving at Cape Cod in late November. Most of the passengers remained on board until mid-December, when they docked at Plymouth Rock.
