Battle of Bosworth Field
The setting
Near Ambion Hill, Leicestershire, England — the site relocated roughly two miles by the 2009 survey
Open ground with marshy patches. ⚠ The location is a live correction: every surviving text agreed on a site that lead-shot scatter and a silver-gilt boar badge moved about two miles in 2009.

Recorded sideRoyal army of Richard III
Recorded resultdestroyed; the king killed on the field
Decisive Tudor victory. Richard III was killed — the last English king to die in battle — and the Plantagenet dynasty ended on the field.
How the atlas explains it
Richard saw Henry’s standard separated from the main body and charged it personally with his household cavalry, coming within yards of him. Two of the four contingents present did not fight for the man they had come with: the Stanleys committed against him and Northumberland’s rearguard never engaged. ⚠ WHY EITHER DID SO IS THE ATLAS’S CLEAREST CASE OF SOURCES AGREEING ON THE ACT AND DIVIDING ON THE REASON.
What followed
Ended the Plantagenet dynasty and began the Tudor. ⚠ FOUR SIDES — the only battle in the atlas with more than two, and two of them present without fighting for the side they arrived with. A two-side schema cannot represent this day at all.
