The boys rescued from a Thai cave were passed "sleeping" on stretchers through the treacherous pathways, a former Thai Navy SEAL who was the last diver to leave the Tham Luang complex told AFP today.
The details of the complex operation are among the first to emerge from a rescue effort to save 12 boys and their football coach that has been shrouded in secrecy since it began on Sunday and ended successfully three days later.
"Some of them were asleep, some of them were wiggling their fingers... (as if) groggy, but they were breathing," Commander Chaiyananta Peeranarong said, adding that doctors stationed along the dark corridors of the Tham Luang cave were constantly checking their condition and pulse.
"My job was to transfer them along," he said, adding the "boys were wrapped up in stretchers already when they were being transferred".
Thailand's junta chief told reporters yesterday that the group had been given a "minor tranquiliser" to help calm their nerves.
But he denied they were knocked out for the miraculous rescue.

The lack of information about the meticulously planned rescue had baffled observers given that the team were extracted safely.
The members of the "Wild Boars" team, aged 11-16, had no experience in scuba diving, and the death of an ex-Navy SEAL who had helped install oxygen tanks in preparation for the rescue underscored the dangers of the mission.
Thailand said it had called on 13 "world class" divers to help with the unprecedented job, one of whom was Australian Richard "Harry" Harris, a diver and professional anaesthetist.
Rescue chief Narongsak Osottanakorn told reporters today that the entire operation would not have been possible without the unique skills that Harris brought to the mission, though he did not elaborate.
The international bid to extract the team garnered attention from around the world after the team found themselves trapped on June 23 when they entered the cave after practice and were blocked by floodwaters.
