Which two details are most important to include in a summary of the excerpt? excerpt from Robinson Crusoe
by Daniel Defoe

At length I spied a little cove on the right shore of the creek, to which with great pain and difficulty I guided my raft, and at last got so near that, reaching ground with my oar, I could thrust her directly in. But here I had like to have dipped all my cargo into the sea again; for that shore lying pretty steep—that is to say sloping—there was no place to land, but where one end of my float, if it ran on shore, would lie so high, and the other sink lower, as before, that it would endanger my cargo again. All that I could do was to wait till the tide was at the highest, keeping the raft with my oar like an anchor, to hold the side of it fast to the shore, near a flat piece of ground, which I expected the water would flow over; and so it did. As soon as I found water enough—for my raft drew about a foot of water—I thrust her upon that flat piece of ground, and there fastened or moored her, by sticking my two broken oars into the ground, one on one side near one end, and one on the other side near the other end; and thus I lay till the water ebbed away, and left my raft and all my cargo safe on shore.
