The first took place sometime around 1995 on a headland called Les Landes to the North of the island. The area was heavily fortified by the Germans during WW2 using slave labour. Many slave workers died on the island during these constructions. It was a summers night just after sunset. We'd been at the headland for a while just catching the sunset. There is one road in and out of the area. Nobody had arrived since we had been there for the previous hour or so, on car or foot. The headland is flat, with only the bunkers giving any cover. We were at the most northerly end, about 5 minutes walk away from the bunkers, in a car park in front of the ruined Grosnez Castle. We had a clear view of the surrounding area for half a mile or so. Nobody was around. I turned to mention to my girlfriend to suggest that as it was now getting dark and colder we may aswell get back to the car. I was standing in the centre of the empty carpark at this point (which is a totally flat gravel area, about 70 feet in lenght and 30 or so feet wide). Suddenly, coming from what sounded like about 4 feet behind my right shoulder, clear as day, came a shout of "Jah!" in German. I span around expecting to see someone there, but nothing. Nobody could have entered the area without us seeing, and if they had, there was nowhere to hide as the area is totally flat - it's so flat they put the islands Horse Racing track there. The area is very windswept during the winter months, so sound could carry, however, during the summer it's stiflingly still, with no wind, very stuff - as was the case during the night in question.
