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".
