Jake writes to Robert Cohn in Spain to say that he and Bill will meet Cohn at Bayonne (near the French-Spanish border), to go fishing together. At a café that evening, Mike Campbell (who is drunk again) invites himself and Brett along on the excursion, and they arrange to rendezvous in Pamplona. Brett tells Jake that Cohn was with her in San Sebastian before Jake and Bill depart Paris via rail. After encountering various Americans on the train (a small family and a large group of Catholic pilgrims), they arrive in Bayonne in the evening.
