In the poem, the conflict between the speaker's personal desire and outside pressures is demonstrated through the speaker's initial confidence in handling the crossing, which is then undermined by Mr. Bixby sending more people to make the speaker nervous. This conflict is resolved when the speaker realizes that they must rely on their knowledge and training rather than second guessing themselves. This resolution points to the theme of relying on one's abilities and not doubting one self.
