Summary

In 1960-61, Scottish peace activists and national disarmament groups protested the establishment of a US Navy Polaris submarine base at Holy Loch, Scotland. The campaign involved marches, sit-ins, and nonviolent occupations aimed at preventing the base’s operation. Despite widespread protests and arrests, the base remained operational until 1991, making the campaign unsuccessful in its primary goal.

Background

In November 1960, the US and British governments agreed to use Holy Loch, Scotland, as a base for Polaris missile submarines, sparking local and national opposition. Opponents feared Americanization, risks to local shipbuilding, and nuclear attack, while national groups sought unilateral nuclear disarmament. Public support for disarmament was only 20% at the time.

What happened

In December 1960, a Glasgow rally of 2,700 protesters and internal government debate delayed the arrival of the submarine tender USS Proteus until after Christmas [source: nv-database]. On 18 February 1961, 5,000 staged a sit-in at Whitehall, and a Glasgow march drew 4,000-10,000 people [source: nv-database]. The DAC organized direct actions, including a planned occupation of the base, and local ‘Glasgow Eskimos’ attempted to block the Proteus with kayaks on 3 March, but lacked sufficient boats [source: nv-database]. In May, a 465-mile march from London reached Holy Loch with 35 participants, and on 21 May, 16 canoes and 70 protesters tried to board the Proteus, facing water hoses and arrests; 200 held a 22-hour sit-in at Ardnadam pier, with 32 arrested [source: nv-database]. In September, the Committee of 100 led demonstrations, with 351 arrested at Holy Loch and 12,000 at an illegal Trafalgar Square protest [source: nv-database]. The campaign lost momentum due to internal disagreements between the DAC and trade unions/political officials, and the base remained until 1991 [source: nv-database].

Key people & organizations

  • Campaign for Nuclear Disarmament (CND)
  • Direct Action Committee Against Nuclear War (DAC)
  • Committee of 100
  • Glasgow Eskimos
  • British government
  • US Navy
  • Harold Macmillan

Outcome

Verdict: lost.

The campaign failed to achieve its goal of preventing the base’s establishment; the US Navy remained at Holy Loch until 1991. Internal divisions between the DAC and trade unions/political officials reduced unity and momentum, and the government’s repressive measures, including arrests and bans on demonstrations, limited the campaign’s effectiveness.

Lessons

  • Internal unity among diverse coalition partners is critical for sustaining a campaign’s momentum.
  • Nonviolent direct actions can generate significant public attention but may not overcome determined government opposition without broader political support.
  • Combining local grievances with national issues can broaden a campaign’s appeal but may also create tensions between different factions.
