The Tenasserim range between the Khwae Noi and the Three Pagodas pass is a week of forest with no town: the pass is the low saddle over the range and the shortest land road between the Gulf of Siam and the Andaman sea, and the corridor is the stretch that makes it expensive to use and easy to ambush (board).
Karen, Mon and other hill villages (modern terms, not documented for 1200) live here; the tin of the streams moves along the road. The Khmer outpost of Muang Sing watches the road; no Pagan or Mon force is dated against it. The Thai-Myanmar border is the seam with the Burma records: Pagan's reach beyond the range, and the Mon coast, are theirs to write.

The campaign board: alluvial tin in the streams of the range, documented only in much later centuries, resting on the geology and on tin moving along the Three Pagodas road; no source we read names the peoples of the corridor in 1200.
Overlord
None attested; Muang Sing watches the road and Pagan lies across the range (the Burma researcher's).
What it holds
- Hill villages and swidden fields
- The Three Pagodas road and its crossings
- Tin in the streams (later documentation)
How things stand that morning
An unwatched corridor; no event.
Wealth
Tin, forest goods.
Places of note
- Three Pagodas pass: Saddle over the range.
- Tenasserim tin workings: Streams of the range (board).
Where the sources disagree
- The campaign board entry tenasserim-tin-workings: 'contested', resting on geology; we treat it as unproven for 1200.
Evidence: Geography and the campaign board.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
On the map: A block on the Thai side only.
