The first protest action undertaken at Greenham involved women chaining themselves to the fence of the base in September 1981. The most well-known protest actions that the Greenham women undertook were the "Embrace the Base" event and their human chain protests. At "Embrace the Base", 30,000 women held hands around the perimeter fence. In April 1983, the Greenham women and their supporters created a 14-mile human chain. In December of that year, another human chain was created, circling around the fence, while some parts of the fence were cut. In at least once instance, the women dressed as witches and attempted to cut down the base's fence.
