The East Africa Squadron operated continuously from the 1850s through to the early years of the twentieth century, when the trade had been sufficiently suppressed and British colonial presence on the East African coast made a dedicated anti-slavery patrol less necessary.
The financial cost was sustained over decades. Ships had to be maintained on station thousands of miles from home. The depot at Zanzibar required permanent infrastructure. The diplomatic effort required to maintain and extend the treaty framework with the Arabian sultanates consumed significant Foreign Office resources alongside the naval budget.
The human cost on the East Africa Station was real, though less extensively documented than the grim mortality records of the West Africa Squadron. The West African coast was notorious as one of the most lethal postings in the Royal Navy, with death rates from malaria and yellow fever that far exceeded any other station. The East African coast and the Indian Ocean were somewhat less deadly, but tropical disease remained a constant hazard, and the close-quarters nature of dhow interception carried its own dangers.
What is documented is the sustained commitment. The Royal Navy maintained a presence on the East Africa Station for roughly fifty years after the 1873 treaties. That is not a token gesture. It is a prolonged military and diplomatic campaign against a trade that had no connection to British commercial interests and that Britain had no obligation under international law to suppress. Britain chose to fight it anyway.
The East Africa Squadron represents the same underlying reality as its Atlantic counterpart: a country that had participated in slavery and then decided, at genuine cost to itself, to spend the next century trying to stop it.
