Yesterday I was out on Salisbury Plain, enjoying a bit of wind and rain and open space, to see a little project that may become big. It’s the brainchild of Diarmaid Walshe (a sergeant with an archaeology PhD). As part of their rehabilitation process, soldiers from 1 Rifles injured in Afghanistan are digging an archaeological site. And it’s no ordinary site: they’re on the vast mound of rubbish that reshaped the hill at East Chisenbury around 700BC, a deep spread of black earth so rich with animal bones and artefacts that excavating it is like turning over a decayed museum store. We don’t understand it. But sometimes there is more to archaeology than just understanding the past.
