It sounds like something out of the latest James Bond blockbuster, with epic scenery and villains to match. Birmingham accountant Joe Bates told Emma Brady how he was taken 'hostage' on holiday.
Cooped up in a freight container with a bucket toilet and prison-style bunk, Joe Bates had no idea when he would see his family again.
Being held in custody in the Far East by security men working for an American mining company was not exactly what the 51-year-old Birmingham accountant had in mind when he started his climbing holiday.
Despite having conquered Mont Blanc in the French Alps, Kilimanjaro in Africa, and Aconcagua in Argentina, nothing had prepared him for last January's trek.
After one of his friends was seriously injured falling off a perilous rope crossing more than 4,000 metres up Puncak Jaya in West Papua, he knew their party needed help.
With no helicopter able to reach them, the six mountaineers were faced with a choice: hack through a dangerous jungle where they could encounter local tribesmen, with cannibalistic tastes, or take a shorter route through land owned by US mining giant Freeport-McMoran.
It seemed to make sense to take the short-cut towards Grasberg, the world's largest gold mine, which borders the Papuan National Park.
Mr Bates, a partner at Clement Keys in Edgbaston, said: "We had made our way up more than 4,000 metres and had set up a Tyrol traverse and one of our party, Eddie Green, got into trouble halfway across, and ended up hanging upside down in the harness. He was in a very bad way, which is why we had to get off the mountain quickly.
"When the helicopter we flew in on reached base camp it crash-landed, so it was being repaired.
"We knew there wasn't another chopper, so our only options were to hack through the jungle where we risked running into cannibals and armed insurgents, or a shorter trek down to a clearing near Grasberg mine where we could pick up a transport to get Eddie to hospital. We opted for the common sense route and when we reached the mine there was a 4x4 waiting, which we thought was transport for us, but it soon became apparent that we weren't going anywhere."
Unaware they had camped on land owned by Freeport-McMoran, as it was within the national park, the mine's security team were in no hurry to let them leave - and effectively held Mr Bates and his friends 'hostage' for the next six days.
The father-of-two, who lives in Barston, Warwickshire, added: "They clearly didn't want us to die on their doorstep, so they let Eddie and Lee (Holton) go so they could get medical attention, but the rest of us remained in the caves, away from base camp, where they clearly didn't want us to be. Then the next day we were moved to a makeshift 'cell' which was basically an old freight container with prison-style bunk beds, which we all shared with an assortment of rats, wolves and all sorts of wildlife you don't want around you."
The remaining four adventurers were forced to live on rations - one bottle of water and a rice box each, which bore the legend "Come home safely, your family needs you" aimed at the mine workers.
Mr Bates developed altitude sickness, and seized the opportunity to escape to hospital, to call for help.
"I stopped eating and drinking to make my symptoms worse so the security guards would have no choice but to send me to hospital.
"I thought once I was off the mountain I'd be able to make contact with my family and the British embassy, to let someone know we needed help."
When the guards refused to send him to hospital, the rest of the party staged a protest march to the mine. They were unceremoniously sent back to the freight container.
However they were all unaware that Mr Green and Mr Holton had returned to Timika, where they had flown in from, and managed to contact the Foreign Office and Mr Bates' wife and daughter.
Finally, on day four of their incarceration, the Birmingham accountant was taken to Tembagapura Hospital where he was given oxygen through nasal tubes to help ease his condition.
"But I would breathe through my mouth to drastically cut the amount of oxygen getting into the system, so my symptoms would worsen and I'd have to be flown back to Timika.
"When an American doctor said I only had mild altitude sickness and was sending me back up the mountain, which goes against the key recovery mantra of 'descend, descend, descend', I refused - that's when I first met 'Big Dave'."
Built, according to Mr Bates, like a stereo-typical Bond baddie, 6ft 10in David Mintle, Freeport-McMoran's head of security and ex-Special Services officer, gave him two options. "Either go back up the mountain or spend a few years in an Indonesian jail for trespassing."
"That was a real kick in the stomach because I honestly thought the Americans would help us," he added.
"I read him what's written on the inside of the British passport, 'to allow the bearer to pass freely and without hindrance, and to afford the bearer such assistance and protection as may be necessary', but Dave just said 'that cuts no ice here'.
"It was at this point that I began to wonder if I would see my wife Denise and our two daughters, Danielle and Lara, again and realised I couldn't give up."
Another attempt to be returned to hospital, by faking a collapse, proved unsuccessful and it was back to the container, where the reunited gang passed the long hours by reading a book, Holding On by Jo Gambi, "which was an awful book but helped us all pass the time, we all swapped sections to pass the time".
Finally, on January 10, the team got the news they had been waiting for from 'Big Dave'.
"After a flurry of spurious phone calls, Dave announced he was going to get us a chopper. Then after a few more calls, it was 'Right I'll take you myself, you've got 30 seconds to get your gear together and go'.
"We had no idea what prompted this turn of events but were later told that Lee had called my daughter who started a chain reaction by informing West Midlands Police who then contacted the Foreign Office, prompting talks with Freeport's US headquarters."
After all four explorers were given a thorough medical, they were taken to the Sheraton Hotel in Timika, where they were able to enjoy the simple luxuries of a bath, clean clothes, a hearty meal and a good night's sleep.
"We were in the same clothes we had on at the start of the climb, so we all looked and smelled pretty awful, so this was just the ticket, but it was such an about-face by Grasberg's security team we still didn't trust it 100 per cent," said Mr Bates.
"All we'd done was innocently climb Puncak Jaya and after the helicopter accident and Eddie's injuries, we somehow ended up being treated like caged animals. I was threatened with prison and the whole experience had been very strange."
At 10am on January 12 the climbers boarded a flight to Bali to be reunited with their friends and family.
"This hasn't deterred me from travelling and climbing, but maybe I'm not in such a particular hurry to return to West Papua and Puncak Jaya," added Mr Bates.
