Why it matters
Yorktown broke the British ministry's capacity to continue the same offensive war in North America, but it did not itself produce peace, settle sovereignty, or end violence across the continent.
Why this provisional tier
This tier predates canonical assessment v1. It remains a research hypothesis and must not be used as settled label priority.
The surrender was the decisive military crisis that made negotiations and a change in British policy possible, produced by a coalition rather than an American army acting alone.
Counterfactual test: Without French naval superiority and coordinated siege forces at the Chesapeake, Cornwallis could have escaped or been reinforced, prolonging major British operations and altering the terms or timing of peace.
The event is a military culmination, not a universal ending. Keeping the later peace, evacuations, Native wars, slavery, and constitutional settlement as separate records prevents Yorktown from swallowing their histories.
