Crusoe realizes he's all alone with no supplies, only a "Knife, a Tobacco-pipe, and a little Tobacco in a Box" – he proceeds to have a meltdown (41).
After finding water, Crusoe climbs up a tree to sleep and rest.
Waking, Crusoe decides he needs supplies, so he swims out to the still intact ship. (It wasn't torn to bits by the waves after all.)
Crusoe snags food, clothes, spirits, tools, ammunition, and arms. He then makes a raft out of some of the ship materials and floats them all back to shore.
Crusoe, even though he knows nothing of the land or where he is, must now figure out where to set up camp. Surveying the land, he sees that the island is barren and, he guesses, uninhabited. He builds a hut on the shore.
Crusoe makes another trip out to the ship for supplies. He fortifies his hut area by adding a tent, and then finally goes to sleep.
Crusoe continues to make daily trips out to the ship to strip it of any useful supplies. After thirteen days, he has made eleven trips back to the ship.
On his last trip to the ship, he finds gold and silver. He starts to take the money, but a storm rises up and he swims back to shore. The next morning, the ship has completely sunk.
