Why it matters

The plot threatened a strategic Hudson River position and turned Arnold into a lasting symbol of treason, often obscuring the material, political, and personal conditions of his defection.

Why this provisional tier

This tier predates canonical assessment v1. It remains a research hypothesis and must not be used as settled label priority.

Exposure prevented a potentially serious strategic loss and had a large memory afterlife, though its military effect was the failure of the plan.

Arnold’s name became shorthand for betrayal. The timeline should still distinguish the failed military transaction from the moral emblem later attached to it.
