 LAS DELICIAS, Colombia (AP) — A fortified training camp with classrooms and an obstacle course. Well-appointed
 commanders' quarters with printouts on U.S. anti-terrorism strategy. A bottle of Danish vodka.

 The Revolutionary Armed Forces of Colombia, or FARC, left many items in their jungle camps as they fled a military
 offensive in their former safe haven, giving visiting reporters a unique glimpse into Latin America's oldest and largest
 guerrilla group.

 President Andres Pastrana ceded the safe haven — an area twice the size of New Jersey — three years ago at the
 start of the peace process, but revoked it after talks collapsed.

 Rebel commanders who once sipped imported liquor in bungalows outfitted with televisions, showers and satellite
 phones have retreated to the bush, where they are being hunted by government troops.

 The guerrillas have retaliated by destroying bridges, power stations, towers for electric lines, and telecommunications
 facilities. The government said Monday that 56 towns were without electricity or were rationing it.

 San Vicente del Caguan, the main town in the former rebel stronghold, had no water, telephone service or electricity
 on Monday because of rebel sabotage. Food supplies were dwindling, and roadblocks by rebel holdouts and a ban on
 flights have cut off the town from the rest of the country, said Mayor Nestor Ramirez.

 A small group of FARC rebels found deep in the zone told reporters they had used the three years to ``grow
 stronger'' — exactly what Pastrana's generals had been warning all along.

 One abandoned rebel camp near the village of Los Pozos was protected by a sandbagged guard post. A
 five-foot-deep trench ran along the perimeter. The camp had classrooms and an obstacle course complete with a
 climbing ramp, wooden chin-up bars and cement barbells.

 The camp was eerily silent when reporters visited it Sunday, save for the grunting of a pig and the meowing of a
 kitten, its only occupants.

 Robinson Ramirez, who manages a cattle ranch next door, said the rebels fled right after Pastrana announced
 Wednesday night that the peace process was over and the safe haven would be eliminated at midnight.

 ``I could hear the guerrillas leaving in cars during the night,'' Ramirez said. He had raised a large white flag over his
 farmhouse to let government warplanes know he was a civilian.

 Ramirez said he has heard the drone of airplanes and thud of explosions every night since the government began
 bombing the area. There were no signs of bomb craters or other damage at the camp, however, which is about a
 two-hour drive along dusty back roads from San Vicente del Caguan.

 The camp bore evidence of the rebels' hasty departure. Eggs still lay on a tray near a cooking area. Black threads that
 were being woven into equipment straps were tied to a tree branch — the job half finished.

 The commanders lived in a wood frame structure with canvas walls and had tables, iron beds and showers.

 In a notebook found near an open-air classroom, a rebel had meticulously described how far to aim ahead of different
 types of aircraft to shoot them down.

 Rebels — many of whom are barely in their teens — had also doodled in some notebooks like daydreaming
 high-schoolers. In one, someone had written ``Haylovio.'' Pronounced phonetically in Spanish, it sounds like ``I love
 you.''

 On a blackboard, a message instructed rebels how to respond if civilians ask what would happen if U.S. forces come to
 Colombia: ``You tell them that we will expel the gringos with guerrilla warfare.''

 The U.S. government insists it won't send troops to fight in the South American nation's 38-year war, although it has
 sent special forces during the past two years to train Colombian anti-drug troops.

 The Bush administration is, however, moving to expand its military aid beyond counter-drug efforts. On Monday, a
 senior administration official said President Bush's national security aides will meet this week to discuss ways to help.

 The rebels are clearly concerned about Washington's campaign against terrorism. The U.S. State Department has
 declared the FARC a terrorist organization, along with a smaller guerrilla faction and a rival right-wing paramilitary
 group.

 In another abandoned camp, one for commanders, reporters found a printout of U.S. government policy on terrorism
 in a small library that also had books on Marxist theory and Cuban revolutionary leader Ernesto ``Che'' Guevara.

 The document, which the U.S. Embassy in Bogota put on its Web page after the Sept. 11 terror attacks, says the
 United States will not make concessions to kidnappers of Americans and will provide anti-terrorism assistance to allied
 countries seeking it.
