Why read this explainer

Follow Nicholson's discipline from resistance into collaboration before comparing the bridge's destruction. His pride changes the meaning of an accomplishment whose military purpose serves the opposing side.

PlotGeeks note

The bridge gives Nicholson's pride an accomplishment whose military purpose contradicts his self-image. Its destruction concentrates that irony in a visible object he has worked to preserve.
