him shackled in contorted positions for days were the most common forms of abuse. During "Operation Sandman", soldiers woke Kurnaz every one or two hours to change cages, forced him to stand or kneel 24 hours a day, and deprived him of sleep for three weeks. Toward the end, he was semi-conscious and not able to walk, and they had to drag him from cage to cage. Kurnaz was also put in solitary confinement in a windowless refrigerator and subjected to hypothermia. He was caged in a container in the Cuban sun baking in extreme heat, and in a small airtight box so that over hours and days he suffocated slowly. He was starved or force-fed; subjected to sexual humiliation; and beaten constantly. Detainees were terrorized by the treatment of fellow detainees. A military doctor amputated both legs of a Saudi detainee named Abdul Rahman because of frostbite. Kurnaz watched from the neighboring cage as soldiers beat the legless man's fingers off the chain link fence when he tried to pull himself up to sit on his toilet-bucket. Dragged out for interrogations with his stumps dangling, he would return with his face bloodied from beatings. Another had frostbite on one finger and a military surgeon amputated all his fingers, leaving only his thumbs. A third complained of a toothache and the dentist pulled his healthy teeth. Wounds and fractured limbs, including fingers broken during interrogations, were left untreated. Kurnaz's health suffered over the years but he "tried to avoid being taken to the doctor at all costs. I wanted to keep my teeth, fingers, and legs." American and German intelligence agencies had concluded that Kurnaz was innocent of any involvement in terrorism by early 2002. He was held at Guantanamo under these conditions and brutalized for five more years, until 2007. Military tribunal declares him enemy combatant After two and a half years at Guantánamo, in 2004, Kurnaz was brought before a military tribunal. The Combatant Status Review Tribunals began after the US Supreme Court decision in Rasul v. Bush that detainees had a right to due process and habeas corpus to challenge the grounds of their detention. A Summary of Evidence memo was prepared for each detainee listing the allegations that supported detention as an "enemy combatant". Tribunal rules forbade Kurnaz from seeing or challenging his file. The evidence against Kurnaz included his association with an alleged suicide bomber
