They planted crops and developed new agricultural techniques. The colonists were not familiar with the climate and soil of the New World, so they had to experiment with different crops and farming methods. They eventually developed a successful method of farming that allowed them to produce enough food to survive.
They built fortifications and established a militia. The colonists were vulnerable to attack from both the natives and the Spanish, so they built a series of forts to protect themselves. They also established a militia to defend the colony in the event of an attack.
They received supplies from England. The colonists were not able to be completely self-sufficient, so they relied on England for supplies. These supplies included food, weapons, and ammunition.
They were led by strong leaders. The Jamestown colony was fortunate to have a number of strong leaders, such as John Smith and Christopher Newport. These leaders were able to guide the colony through difficult times and inspire the colonists to work together.
By taking all of these steps, the Jamestown colonists were able to overcome the challenges they faced and establish a successful colony.
