Transcript from Xenonaut agents' interview with Lt. General Thomas L. Palmerston, high commander of NATO forces in Operation Verne.

"For the record, I assumed overall command of NATO ground forces in Iceland at approximately 10.30am on 23rd April 1958. My first action was to establish a perimeter around the crash site to prevent the local civilians accessing the area. Then we locked the place down and awaited the arrival of the Soviet ground forces. I believe the official line was a malfunctioning B-52 bomber had come down. I doubt anyone believed us.

"The bulk of the Soviet forces arrived at 1pm. They looked like good soldiers, mostly paratroopers, probably mixed in with special forces. A couple of their big cargo planes landed at our airstrip and unloaded a handful of T-54 tanks too. I met their commander, a fellow called Mikhail, and he introduced his men as the Soviet Fourth Army. We lent them our trucks and headed over to the crash site together.

"I had soldiers from the 95th Airborne and the 202nd Infantry on the perimeter, supported by half a dozen Patton tanks. We ceded half of the perimeter to the Soviets and, when they were in position, we began our advance. You could see the remains of the UFO from the perimeter - it was heavily damaged, but still in one piece. Everything around the impact site that could burn was either ablaze or had already charred to a cinder. It was a desolate, hellish scene. Gave the men the jitters.

"We slowly tightened the perimeter ring, closing in on the downed UFO until we were about a kilometre away. Then the shooting started. The extraterrestrials were concealed in the shattered hull of their ship and the wreckage around it, and we were advancing over a barren wasteland. There was almost no cover. We were taking horrendous losses from the moment they opened fire.

"Their weaponry seemed to take two main forms, either energy beams or searing bolts of superheated energy. I saw a beam, a thrumming red ray of light, carve a Patton in two. It cut through the steel as if it was just tissue paper. The energy bolts were scything through my soldiers, charring the flesh from the bones of any man unlucky enough to be hit by one. One flicked past and missed me by a couple of yards, leaving me half-blind and tasting the crackling electricity in the air.

"We replied as best we could. Our tanks pounded the crashed vessel with dozens, perhaps hundreds, of cannon rounds. The soldiers stitched anything that moved with streams of machine-gun fire. The battle was fierce, but by mid-afternoon the extraterrestrial return fire had slackened enough that we resumed the advance and tightened the perimeter. I returned to the nearby command post and left the operation in the charge of my assistants. At just before 5:00pm I received a message informing me the perimeter had closed to within half a kilometre of the downed spaceship.

"At 5:07pm a detonation centred on the crash site registering 50 megatons was picked up across the entire globe. I was later informed that the ground-level detonation and peculiar behaviour of the blast meant that it inflicted far less damage on the surrounding area than a conventional nuclear weapon would have, but it still extinguished all life within ten kilometres of the crash site. Windows were reportedly shattered as far away as fifty kilometers. The mobilised elements of the 95th Airborne, 202nd Infantry and Soviet Fourth Army were all wiped out in their entirety - only the staff officers located at the remote command facility survived the blast.

"Later analysis of the seismological data suggested that an extremely large power store had exploded, assumed to be either the vessel's power core or munitions stocks. We guessed the aliens had done it deliberately, knowing they could not hold out forever. In any case, niether NATO nor Soviet scientists were able to find any recoverable trace of the crashed vessel after the detonation, leaving us little the wiser about our alien brethren or their technology.

"Inevitably, the incident was hushed up. I took a lead role in the later press conferences - the official story being a Soviet invasion of Iceland was thwarted by the deployment of nuclear weapons. A permanent joint NATO/Soviet military presence was established on the island as a show of good faith, allowing both sides free access to the remains of the crash site. But, as far as I know, none of the countless military scientists studying the site has ever managed to uncover anything of worth. I doubt they ever will."
