The "Armageddon Scenario": Britain's Secret Plans for a Hong Kong Exodus
London, UK – Declassified documents reveal the extensive and highly sensitive contingency planning undertaken by the British government in the late 1980s, referred to internally as the "Armageddon scenario," to prepare for a potential mass exodus from Hong Kong before and after the 1997 handover of sovereignty to China. This planning, led by the Official Group on Contingency Planning for Hong Kong (MISC 140), aimed to address a crisis that the United Kingdom recognised it could not manage alone.
The plan was designed to respond to several potential triggers for a mass departure: a haemorrhage of confidence, sudden panic, internally generated panic, or Chinese provocation. These were broadly categorised into "pre-1997" and "post-1997" scenarios.
Three-Phase Contingency Framework: Contingency planning was structured around three distinct phases:
- "Green" Phase: The current planning phase, focusing on monitoring the situation, preparing the groundwork for any eventual crisis, and securing international support. Minimal additional expenditure was anticipated during this phase.
- "Amber" Phase: Activated when a crisis appears imminent, requiring decisions on immigration control relaxation, outline plans for chartering aircraft and ships, and steps to improve military asset readiness. This phase could be very short.
- "Red" Phase: Initiated when a mass exodus has begun, involving evacuation, reception, and resettlement operations.
Anticipated Impact on the UK: The documents highlight several critical impacts on the United Kingdom should a mass exodus occur:
- Massive Financial Costs: A large influx would create a "hugely expensive" resettlement problem. Estimates for moving one million people by sea to Taiwan were about £165 million, and flying them to Manila around £40 million, excluding significant consequential and refitting costs. The total cost for one million people going to the Philippines and six months of reception in the UK could be £5.4 billion. Establishing reception centres for 1,000 refugees was estimated at £5 million, and for 100,000 refugees, £500 million.
- Resettlement Challenges: Accommodation, jobs, education, health, and social services would face immense pressure. While around 400,000 empty dwellings might be available, not all could be requisitioned.
- Strain on Transport and Resources: There were serious constraints regarding the availability of aircraft and ships. Securing sufficient transport would be difficult, requiring long lead times and high costs for chartering or leasing. Military assistance would be crucial but limited.
- Immigration Control and Refugee Status: Decisions on immigration control would be tightened, and applications for asylum would likely be more difficult to refuse as many individuals would not possess British Dependent Territory Citizen (BDTC) status.
- International Burden: The UK recognised it could not handle a mass evacuation alone and that securing international support and firm pledges to take refugees would be essential. Diplomatic efforts would be made during the "green" phase to secure commitments from other governments.
- Secrecy and Public Opinion: Maintaining confidence in Hong Kong was a key British policy. The government aimed to prevent public knowledge of contingency planning to avoid panic and ensure stability.
While the declassified documents concerning the "Armageddon scenario" primarily detail the British government's comprehensive contingency planning for a potential mass exodus from Hong Kong, they do reveal certain internal debates, candid assessments of limitations, and strategic concerns that could be interpreted as "opposing voices" or at least significant counterpoints within the planning process. These are not outright rejections of the plan's necessity, but rather critical perspectives on its feasibility, scope, and communication.
Here are some of the key "opposing voices" or critical viewpoints identified in the sources, along with their reasonings:
The Home Office (specifically A.J. Langdon, representing the Immigration Department):
- Reasoning: The Home Office expressed concern over its initial perceived exclusion or under-representation in the composition and terms of reference for the Official Group on Contingency Planning for Hong Kong (MISC 140). They argued that it would be a "mistake" to limit their involvement given the broad implications of the scenarios under review, particularly regarding immigration control and refugee status. They also highlighted the potential difficulties in refusing asylum applications from individuals who would not possess British Dependent Territory Citizen (BDTC) status after 1 July 1997, noting that such applications would be "more likely" and "more difficult to refuse" in practice. This implies a concern about the practicalities and legal complexities of managing a large influx under existing immigration frameworks.
W.D. Reeves (Cabinet Office, reflecting Treasury/logistical concerns):
- Reasoning: Reeves made a stark assessment regarding the practical and financial capacity of the United Kingdom to handle a mass exodus alone. He stated unequivocally that "it is financially impossible for the UK to mount such an evacuation and resettlement exercise alone" and that it would be "physically impossible to get everyone out". This underscores a critical "opposing voice" to any notion that the UK could manage the crisis unilaterally, thereby stressing the absolute necessity of international support and firm pledges from other countries. This perspective highlights the inherent limitations of the UK's resources for such a large-scale event.
D.G. Manning (Cabinet Office) and other officials regarding "possible leaks" and public confidence:
- Reasoning: There was significant concern about the secrecy of the contingency planning and the potential for any public knowledge or "leaks" to cause panic or undermine confidence in Hong Kong. Manning, for instance, advised against updating the "Armageddon paper" if it contained "alarming" passages, stressing that British policy aimed to maintain and strengthen confidence in Hong Kong. This suggests a "voice" cautioning against actions that, while part of necessary planning, could inadvertently trigger the very crisis they sought to manage or prevent. He also pointed out that the Governor of Hong Kong had not been consulted on the contents of the paper.
The "Corry Report" (External Economic Analysis):
- Reasoning: While not an "opposing voice" within the government's planning group, Professor Bernard Corry's economic analysis on the impact of mass Hong Kong immigration on the UK, commissioned by the South China Morning Post, offered a detailed perspective on the potential challenges. The report noted that its "best case" scenario for the UK's economic impact was predicated on the assumption of managed immigration between 1990 and 1998, suggesting that unmanaged scenarios would lead to greater difficulties. It highlighted potential strains on housing, jobs, education, and social services in the UK from a large influx, even while acknowledging potential economic benefits. This served as an external, analytical "voice" providing a realistic (and in some respects, sobering) assessment of the economic and social implications, implicitly arguing for proactive measures to mitigate these impacts.
In essence, these "opposing voices" were less about fundamental disagreement with the need for contingency planning and more about the practicalities, political sensitivities, and resource limitations that would shape any response to the "Armageddon scenario." They functioned as internal checks and external realities that informed the refinement of the plan.
This is akin to a ship's crew debating the best route and provisions for an unexpected storm: they all agree a storm is coming and a plan is needed, but they may have differing opinions on the ship's actual seaworthiness, the quantity of supplies, and the safest course of action, all of which are critical for survival.
