The ghostly apparitions are part of a performance project marking the presence 75 years ago of 10,000 American GIs, who came to North Devon to prepare for the D-Day landings of the Second World War. The project, devised by Multi Story Theatre, is part of Devon D-Day, a summer long programme of events commemorating the local contribution to the Normandy landings in 1944. Preparations are cloaked in secrecy, but it is understood that young men from across the local area have been kitting themselves out in suitable attire and are receiving final briefings behind closed doors. Bill Buffery of Multi Story Theatre said: "We're not telling anyone anything much about what's happening, but if anyone spots these mysterious figures while they're out and about in North Devon this weekend, we hope they'll share what they see using the special hashtag #OverHere." The Devon D-Day project commemorates the British and American military presence on the North Devon coast in 1943-44, as soldiers used the area's beaches, estuaries and sand dunes to prepare to invade German-occupied continental Europe. The project also recalls the impact of this presence on local communities and landscapes. A free What's On programme listing all of the events in Devon D-Day is available from tourist information and visitor centres and museums. Devon D-Day is supported using public funding by the National Lottery through Arts Council England, with additional financial support from North Devon Council, North Devon Coast AONB Sustainable Development Fund and North Devon Marketing Bureau.
