In what chapter did Holden lose the fencing gear?

Holden Caulfield tells the story from a retrospective perspective; he begins, in chapter 1, by telling readers that instead of his "whole goddam autobiography," he is going to talk about "this madman stuff that happened to me around last Christmas." Holden is in recovery from a breakdown, and as the novel opens, he is leaving yet another boarding school, Pencey Prep. In the first chapter he explains why he isn't at the football game that most of his classmates are attending. He looks down at the field and confesses that he isn't there because he and the fencing team have been in New York for a fencing match with another school. However, the match does not take place because Holden was in charge of transporting the equipment and left it on the subway train by mistake. Consequently, as the novel opens, he has returned prematurely from the match and suffered the team's ostracizing for his mistake. Holden claims to find the situation "pretty funny, in a way."

In chapter 1, Holden recalls leaving the fencing equipment on the subway in New York City.
In the first chapter of the novel, Holden Caulfield stands on the top of Thomsen Hill overlooking the football game between Pencey Prep and Saxon Hall. Holden mentions that the reason he is not down at the game is because he has just arrived back at school from a trip to New York with the fencing team. Holden then mentions that they did not have the meet against McBurney School, because he left the fencing equipment on the subway. Holden goes on to defend his mistake by insisting that it was not his fault that he left the fencing gear on the subway; he claims that he was too distracted by reading the map to know when and where the team should have got off. After losing the equipment on the subway, Holden says that the entire team ostracized him on the ride back to Pencey Prep.
