1620 – Plymouth Colony: William Bradford and the Mayflower Pilgrims land near what is now known as Plymouth Rock in Plymouth, Massachusetts. The Mayflower dropped anchor in Plymouth Harbor on December 16 and spent three days looking for a settlement site. They rejected several sites, including one on Clark's Island and another at the mouth of the Jones River, in favor of the site of a recently abandoned settlement which had been occupied by the Patuxet tribe. The location was chosen largely for its defensive position. The settlement would be centered on two hills: Cole's Hill, where the village would be built, and Fort Hill, where a defensive cannon would be stationed. Also important in choosing the site was the fact that the prior villagers had cleared much of the land, making agriculture relatively easy. Fresh water for the colony was provided by Town Brook and Billington Sea. There are no contemporaneous accounts to verify the legend, but Plymouth Rock is often hailed as the point where the colonists first set foot on their new homeland. On December 21, 1620, the first landing party arrived at the site of Plymouth. Plans to build houses, however, were delayed by bad weather until December 23. As the building progressed, 20 men always remained ashore for security purposes while the rest of the work crews returned each night to the Mayflower. Women, children, and the infirm remained on board the Mayflower, and many had not left the ship for six months. The first structure was a common house of wattle and daub, and it took two weeks to complete in the harsh New England winter. In the following weeks, the rest of the settlement slowly took shape. During the winter, the Mayflower colonists suffered greatly from lack of shelter, diseases such as scurvy, and general conditions on board ship. Many of the men were too infirm to work; 45 out of 102 pilgrims died and were buried on Cole's Hill. Thus, only seven residences and four common houses were constructed during the first winter out of a planned 19. By the end of January, enough of the settlement had been built to begin unloading provisions from the Mayflower.
