The line comes from Chapter 1 of Treasure Island. The line can be more easily understood in the context of what becomes before and after it. "He" in this case refers to a lodger at the inn of the narrator's father. The "crossed" refers to a story he is about to tell, in which someone crosses (stands up to) the lodger.
"...towards the end" is unclear from a quick skim of the chapter, but likely alludes to the end of the narrator's father's time at the inn, or to the end of his father's life, or the end of the lodger's stay.
"...far gone" and "took him off" refers to the narrator's father, and his physical and/or mental deterioration, and possibly, death.
