Fortress Britain 3 with Gordon Barclay

The third part of our Fortress Britain series takes us north, where Gordon Barclay joins us for a deep dive into Scotland’s defense plans during the Second World War—and how they’ve been misunderstood ever since.

We talk about stop lines, airfield vulnerabilities, pillbox design, and the sheer logistical push it took to prepare the country for invasion. Gordon breaks down how anti-tank ditches, coastal artillery, and naval fortresses fit into a larger strategy—one that included Polish and Norwegian forces defending the Scottish coast. We also look at how these defenses evolved, what still survives today, and how some of it is only just being re-discovered.

Toward the end, we discuss how Gordon’s research was misrepresented during Scotland’s independence debate, and why wartime history—when twisted—can still fuel modern mythmaking.
