Fusiliers Dougald McCaughey, 23, Joseph McCaig, 18, and his brother John, 17, were executed on a remote mountain road in Northern Ireland on March 10, 1971.

The off-duty troops were drinking in Belfast bars when three men pretended to befriend them then lured them to their deaths with the promise of meeting young women at a party.

They were lined up at the side of the road and shot in the back of the head at close-range at White Brae in Ligoniel, overlooking north Belfast.
