EDINBURGH, SCOTLAND—A network of trenches dug in 1914 by soldiers headed to France to will be preserved in Scotland. In the first step of the project, military archaeologists will map the trenches with GPS equipment. “We do not know anything about the extent of the trenches, what condition they are in, or the type of trenches they are. The results of this survey will be vital in helping us plan how best to manage the future of this important piece of military heritage,” said Phil Abramson of Scotland’s Defense Infrastructure Organization.
