Hi. Although you submitted a text, you did not submit any questions regarding it. This prevents me from giving you any answers. However, to help you out, I'll explain what the text presented means. Hope it's useful.
The text posed in the question above is an excerpt from "Of Plymouth Plantation" written by William Bradford, where he presents a real account of the life of the first English settlers, recently arrived in America. In this excerpt, he shows how the arrival in America was very challenging for all the settlers. They had already faced problems on the way between England and America and when they arrived in the new world, they landed in a place where there was no one to help them with anything. The settlers had neither house nor food, they had to face the harsh winter without any resources to protect them, they did not know any place they could shelter and lived in constant concern about being attacked by the "savages", that is, the natives.
