British Royal Navy Involvement in Biafran Blockade and Alleged Starvation Contribution

SUMMARY

This dossier investigates a Reddit claim concerning the British Royal Navy's direct involvement in the blockade of Biafra and its alleged contribution to starvation. The claim, found in a Reddit discussion about historical British activities, attributes this specific action to the Royal Navy. While the Royal Navy has a documented history of enforcing naval blockades, such as the Blockade of Africa in the 19th century and the blockade of Germany during World War I, no academic or official sources provided in the raw sources corroborate a direct Royal Navy blockade of Biafra during the Nigerian Civil War (1967-1970) or its direct contribution to starvation there. The available sources primarily discuss other historical British blockades or general methods for historical research, leaving the Biafra claim currently unverified.
