The arson campaign that targeted the 'white settlers' of Wales
In short: Between 1979 and 1993, a shadowy paramilitary group launched 328 attacks across Wales. Their primary targets? Holiday cottages owned by the English. Driven by a fierce nationalist sentiment against rising housing prices and the perceived threat to Welsh-speaking communities, they waged a decade-long campaign of fire and letters.
The group, known as Meibion Glyndŵr (Sons of Glyndŵr), emerged in 1979 following a failed devolution referendum. They targeted English-owned holiday homes, particularly in the Llŷn Peninsula, viewing these properties as symbols of economic displacement. Their tactics were often crude, involving devices made of sulphuric acid, wax tubes, and condoms. By late March 1980, the campaign had already destroyed 30 homes in a single month, leading to a massive police crackdown known as Operation Tân ('fire').
The identity of the group remains shrouded in historical ambiguity. While Meibion Glyndŵr eventually claimed responsibility for attacks, other organizations like Mudiad Amddiffyn Cymru (MAC), Cadwyr Cymru, and the Workers' Army of the Welsh Republic (WAWR) also claimed responsibility for various bombings and arson during the same era. Some theorists suggested Meibion Glyndŵr was simply a third iteration of the older MAC movement. The group's rhetoric was stark, frequently labeling English immigrants as "white settlers" and declaring that "every white settler is a target."
The campaign's peak in the late 1980s saw a shift toward political targets, including letter bombs aimed at Conservative Party MPs. Despite the scale of the violence—which included 228 arson attacks and various bombings of government and industrial offices—the group was remarkably elusive. Only one person connected to the group was ever arrested in 1993, marking the end of a campaign that successfully forced the state to use the Prevention of Terrorism Act 1976 to conduct large-scale dawn raids and roadblocks across the Welsh countryside.
The name itself serves as a historical anchor, referring to Owain Glyndŵr, the 15th-century leader of a major Welsh rebellion against English rule. By adopting his name, the paramilitary group linked modern economic grievances to centuries of resistance, framing their arson as an act of "despair" against the destruction of rural Wales.
