Billy Bones (“the captain”) Character Analysis

I remember him looking round the cove and whistling to himself as he did so, and then breaking out in that old sea-song that he sang so often afterwards:
“Fifteen men on the dead man’s chest—
Yo-ho-ho, and a bottle of rum!”

Now, if I can't get away nohow, and they tip me the black spot, mind you, it's my old sea-chest they're after; you get on a horse—you can, can't you? Well, then, you get on a horse, and go to-well, yes, I will!—to that eternal Doctor swab, and tell him to pipe all hands—magistrates and sich—and he'll lay'em aboard at the 'Admiral Benbow'—all old Flint's crew, man and boy, all on 'em that's left. I was first mate, I was, old Flint's first mate, and I'm the on'y one as knows the place. He gave it me at Savannah, when he lay a-dying, like as if I was to now, you see.

Now, to tell you the truth, from the very first mention of Long John in Squire Trelawney’s letter, I had taken a fear in my mind that he might prove to be the very one-legged sailor whom I had watched for so long at the old “Benbow.” But one look at the man before me was enough. I had seen the captain, and Black Dog, and the blind man Pew, and I thought I knew what a buccaneer was like—a very different creature, according to me, from this clean and pleasant-tempered landlord.

“I were in Flint’s ship when he buried the treasure; he and six along—six strong seamen. They was ashore nigh on a week, and us standing off and on in the old Walrus. One fine day up went the signal, and here come Flint by himself in a little boat, and his head done up in a blue scarf. The sun was getting up, and mortal white he looked about the cutwater. But, there he was, you mind, and the six all dead—dead and buried. How he done it, not a man aboard us could make out. It was battle, murder, and sudden death, leastways—him against six. Billy Bones was the mate; Long John, he was quartermaster; and they asked him where the treasure was. ‘Ah,’ says he, ‘you can go ashore, if you like, and stay,’ he says; ‘but as for the ship, she’ll beat up for more, by thunder!’ That’s what he said.”
