As the article says the eviction team waited until numbers at the camp were low and took the camp by surprise in the morning. Low numbers has been a major problem at the camp right from the beginning, on the day of the eviction there were only 5 people on site. The site had built up a fairly impressive amount of defences (18 months worth) but no one was willing to occupy these positions. In the end the 5 people on site when the eviction came didn't want to be arrested so left quietly with their hands in the air and decided not to put up any resistance.
