SAN ANTONIO, Texas (CNN) -- Three Americans rescued last week from captivity in the Colombian jungle will return to their homes Saturday, the U.S. Army South said.

Marc Gonsalves, Thomas Howes and Keith Stansell have been undergoing a reintegration process at Brooke Army Medical Center in San Antonio, Texas, since their return 10 days ago to the United States.



The men were among 15 hostages, including former Colombian presidential candidate Ingrid Betancourt, who were rescued July 2 in a Colombian military operation.



The men carried with them a metal lock, a bullet and a chess board made of cardboard -- small items that are reminders of the years they spent away from their families, cut off from the world outside the jungle, seeing only fellow hostages and their captors, the Revolutionary Armed Forces of Colombia (FARC).



The group had held the three U.S. government contractors hostage since February 2003, after their plane crashed in a remote region of the South American country.



"They don't recognize humanity, they don't recognize human rights. They're animals. They're terrorists," Stansell said of the FARC. "We don't want to exaggerate what happened. We just want to tell the truth."



The men painted a gruesome picture of their captivity, describing months in which they were ordered not to speak to each other and an initial campsite where they lived with a rat's nest above them. They slept on the floors of drug labs and were forced to march for hours while chained.



Chains were very much a part of their captivity.



"That was put around my neck every night," Stansell told Headline News' Robin Meade on Thursday, holding a heavy industrial lock. "This lock, with 5 meters of chain -- thick, 1-inch links -- went to his neck," Stansell said, pointing at Gonsalves.

Gonsalves also held small wooden chess pawns he had carved using a broken piece of a machete. It took three months to make them, he said.  Watch Gonsalves talk about how chess made him feel free »



"We're in chains, sitting Indian-style on a piece of plastic, just playing chess," Stansell said. "And when you're doing that, you're free."



Howes, the most reticent of the three, carried with him a bullet from a commander who had once threatened to kill him.



But despite the chains, the intolerable living conditions and the isolation, being away from their families was possibly the most difficult hardship to endure, the men said.



"I remember my darkest day was in the first month of our captivity," Gonsalves said. "We were, at that point, locked in boxes at night. ... That night, I dreamt about my daughter, who was my little girl and still is. And I had this dream about her that was so real; she was sitting on my lap, and ... she had little braids in her hair," he said.  Watch Gonsalves talk about his darkest hour »



"It was a wonderful dream, with all of my family. But the problem was, I woke up."



Colombian government agents infiltrated the FARC leadership over several months, eventually tricking the rebels into moving the hostages by saying a humanitarian group wanted to check on them.



A helicopter carrying fake rebels picked up the hostages at a rendezvous point on July 2, ostensibly to take them to another rebel camp. But it was actually a Colombian military helicopter and the hostages were flown away, free, without a shot being fired. Read about the daring rescue mission



The FARC, which has been fighting with the Colombian government and other paramilitary groups for decades, defends the taking of captives as a legitimate act of war. The group is thought to be holding about 750 prisoners in the nation's remote jungles.
