Richard Harris’s medical documentation of the sedation protocol — the specific approach used for each extraction, the monitoring conducted during transit, the outcomes observed on arrival at Chamber 3 and at the surface — represents a unique contribution to medical knowledge about sedation in extreme and resource-limited environments. His subsequent work disseminating that knowledge to the broader medical and cave rescue communities transformed a one-time improvised solution into something with ongoing clinical value.
The Thai government’s official record of the operation — preserved in administrative and military archives and partially reflected in the commemorative museum being developed at the site — documents the command decisions, the resource allocations, the international coordination, and the specific contributions of the thousands of people who participated. That record is the institutional basis for the annual observances that keep the rescue present in Thai public memory.
What the records collectively preserve is not just what happened but how it happened: the sequence of decisions, the coordination of capabilities, the management of uncertainty. For future rescuers facing comparable situations, that record is more valuable than the narrative. The narrative tells you that it was done. The record tells you how.

## A Cave in Chiang Rai, Remembered
Tham Luang Nang Non translates roughly as “Great Cave of the Sleeping Lady.” The name refers to a local legend about a princess who is said to rest inside the mountain, and the shape of the Doi Nang Non range — seen from the right angle — does suggest a reclining figure.
The cave that existed before June 23, 2018, was a recreational destination: a large, accessible limestone system popular with local visitors and known to the spelunking community as a site worth exploring. Its deeper sections, the ones that flooded and that required technical diving to navigate, were known to specialists and largely unexplored beyond what the survey teams had documented.
