The Forgotten Siege: How Oba Kosoko’s Tactical Error Changed the Fate of Lagos
By the National Patriots. April 2025
A Kingdom on the Brink
In the dawn of January 1852, the cannons of the British Royal Navy thundered off the coast of Lagos, marking the beginning of one of the most consequential battles in West African colonial history. The British invasion of Lagos was not simply a clash of muskets and gunboats—it was a calculated betrayal, a story of fractured loyalties, and a fateful miscalculation by one of Yorubaland’s most formidable monarchs: Oba Kosoko.
Kosoko: The Warrior King of Lagos
Oba Kosoko ascended the throne of Lagos in 1845 after ousting his cousin and rival, Oba Akitoye, in a palace coup. Kosoko was no ordinary king—he was a tactician, a diplomat, and a symbol of African resistance against European imperialism. His reign coincided with a pivotal moment in global history when the British Empire, under the guise of suppressing the transatlantic slave trade, was aggressively expanding its colonial reach across Africa.
Kosoko refused to bow to British demands to abolish the slave trade—a move that, although morally indefensible by today’s standards, was economically strategic in that era. Lagos was a flourishing commercial hub, and Kosoko’s resistance to British economic control made him a target.
A Formidable Alliance of Resistance
As British warships approached Lagos in December 1851, Kosoko was ready. Far from being isolated, the Oba had formed a multinational alliance of mercenaries and warriors who pledged loyalty to the Yoruba crown:
Portuguese and Brazilian ex-military men, remnants of the slave trade economy who saw Lagos as a vital node.
Italian and Scottish gunmen, many of them maritime freelancers turned mercenaries.
A legendary force of female Amazons from the Kingdom of Dahomey, dispatched by King Gezo himself in solidarity with Kosoko. These warriors, renowned for their ferocity, served as palace guards and frontline fighters.
Kosoko’s elite guards and Yoruba warriors, armed with gunboats, cannon batteries, and fortified shoreline defenses.
Together, this coalition transformed Lagos into a citadel of resistance. Historian Patrick Cole notes in Modern and Traditional Elites in the Politics of Lagos (1975), “Kosoko’s Lagos was the best defended West African port at the time, with firepower superior to many European colonial outposts.”
The Siege of Lagos: December 26–28, 1851
The British naval squadron, commanded by Commodore Henry Bruce aboard the HMS Bloodhound, began bombardment from the Lagos lagoon. For two days, the attack was confined to long-range artillery and naval shelling, failing to make a successful ground assault. Kosoko’s gunboats returned fire, while Dahomey’s Amazons manned the barricades and snipers countered from concealed rooftops.
However, on the second day of the battle, Oba Kosoko made a costly strategic error: believing the British were retreating, he pulled back some of his artillery and allowed his forces to regroup inland, reducing the pressure on British landing craft. This miscalculation gave the British the window they needed to re-enter the lagoon with reinforcements and better-coordinated assault plans.
Commodore Bruce wrote in his report to the Admiralty:
“The King’s defensive line was impressive, but our second return met with reduced fire. They were not expecting us to land again so swiftly.”
Betrayal from Within: Akitoye’s Role
The battle was not only external. Oba Akitoye, Kosoko’s cousin and exiled rival, had struck an agreement with the British in return for their support in reclaiming the throne. Akitoye promised to abolish the slave trade and open Lagos to British commercial and political influence.
As historian J.F. Ade Ajayi explains in History of West Africa:
“Akitoye’s alliance with the British was more than opportunistic—it represented a shift from resistance to acquiescence that would shape Nigeria’s future for over a century.”
Fall of Lagos and the British Entry into the Region.
By December 28, British forces had successfully landed and launched a ground assault. With cannon fire decimating his defences, Kosoko was forced to retreat to Epe with his remaining warriors. Akitoye was reinstalled by the British in January 1852, and Lagos became a de facto British protectorate, formally annexed in 1861.
This victory opened the floodgates. The British used Lagos as their colonial gateway into what would later become Nigeria. From Lagos, they extended control inland—eventually amalgamating the Northern and Southern Protectorates in 1914.
Legacy: What If Kosoko Had Held Lagos?
The events of the 1851 invasion pose one of the most compelling “what-ifs” in African colonial history. If Oba Kosoko had maintained his defensive posture and successfully repelled the British assault, Nigeria’s colonial timeline might have been drastically altered. The alliance of indigenous African states and foreign mercenaries might have set a precedent for broader West African resistance.
But history favored the Empire—and Kosoko’s single tactical error proved fatal.
Conclusion: A Battle that Redefined a Nation
Today, Kosoko’s legacy is mixed: a king who defied imperialism but whose reliance on the slave economy casts a long shadow. Yet, in the context of Yoruba resistance and African sovereignty, he remains a symbol of fierce independence and a stark reminder that one misstep in battle can alter the destiny of nations.

“Kosoko stood not only for Lagos, but for the right of Africans to decide their own fate—long before independence was a dream.”

Modern-day researchers and governance experts see this episode as more than a relic of colonial history—it is a lesson in strategic sovereignty, self-determination, and the enduring danger of internal betrayal.
“Kosoko’s resistance was not just about the throne of Lagos—it was about who gets to shape Africa’s future. The lesson for today is clear: divided leadership invites foreign dominance. Africa must learn from its past to control its present.”

Oba Kosoko’s Last Stand: How a Tactical Error Opened Lagos to British Rule
In December 1851, British forces launched a naval assault on Lagos under the pretext of suppressing the slave trade. Oba Kosoko, the reigning king of Lagos, refused British interference and mounted a formidable defense with the support of European mercenaries—Portuguese, Italians, Scots, Brazilians—and the famed Amazons of Dahomey, sent by King Gezo.
Lagos was well-armed with gunboats and coastal artillery. For two days, the British were held at bay, firing from their warships without success. But on the second day, Kosoko made a critical error: misinterpreting the British withdrawal as a full retreat, he redeployed some of his defenses, giving the British room to return with reinforcements and launch a decisive land assault.
His rival, Oba Akitoye—exiled earlier—had allied with the British and was reinstalled as king after Kosoko’s retreat to Epe. This paved the way for Lagos’ annexation and Britain’s deeper penetration into Nigeria.

Strangers in Their Own Land: Yoruba Indigenes Call for Protection in Lagos
Lagos indigenes are raising alarms over what they describe as economic and cultural displacement by non-indigenous groups—particularly Igbos—across key local government areas such as Oshodi, Isolo, FESTAC, and Amuwo-Odofin.
Yoruba residents allege being excluded from housing, commercial opportunities, and port-related jobs in their own ancestral land. Reports include cases where Yorubas are forced to pay exorbitant rents to Igbo property developers, while fellow Igbos enjoy preferential treatment. In sectors like clearing and forwarding, claims of monopolization and exclusion persist.
Community leaders are calling on President Tinubu and Governor Sanwo-Olu to act swiftly, warning that unchecked encroachment could lead to unrest. They advocate for lease-only land policies for non-indigenes, economic inclusion quotas, and indigenous protection laws—similar to models used in Dubai, Malaysia, and New Zealand.
> “Lagos is open to all, but we must not be erased in our own land,” said Chief Adebayo Onasanya.
The call is not for exclusion, but equity and respect—to preserve the cultural and economic rights of those who founded Lagos and have sustained it for generations.
