## Core Claim

The 1797 defense is often remembered through San Juan's walls, forts, and official commanders. This follow-up keeps the same event but shifts the map east toward Loiza, Punta Cangrejos, Cangrejos, Martin Pena, and the surrounding route. That view helps show the local militias, neighbors, and Black/pardo defenders who can disappear when the story stays wall-centered.

## Safe Public Claims

1. In 1797, British forces under Ralph Abercromby attacked San Juan / Puerto Rico.
2. National Park Service identifies defenders including Spanish soldiers, the Puerto Rican Fixed Regiment, Puerto Rican Disciplined Militias, and citizens.
3. EnciclopediaPR places British ships off Loiza, in front of Punta Cangrejos / Pinones, and describes movement through the Cangrejos route.
4. EnciclopediaPR names disciplined militias, urban militias, and `milicianos morenos` as part of the local military frame.
5. Milagros Denis-Rosario argues Puerto Rican historiography neglected or silenced the role of Black Puerto Ricans / pardos in the 1797 attack.
6. The public frame should stay careful: the receipt changes when the map includes Cangrejos/Loiza, but no one group should be claimed as the sole reason for the British defeat.

### Map Attribution

Use the map as a current orientation visual, not a historical reconstruction.

## Guardrails

- Do not claim Black/pardo defenders alone defeated the British.
- Do not claim Loiza/Cangrejos alone saved San Juan.
- Treat the map as orientation, not a precise 1797 battlefield reconstruction.
- Avoid exact casualty/count claims unless clipped from a primary or source-carded record.
- Keep public scheduling notes out of the public archive page.
