In the middle of the 1970s, Nigeria was a country in a hurry.
The civil war had ended in January 1970. Oil revenues were rising rapidly, government spending was expanding and the Federal Military Government was pursuing an ambitious programme of reconstruction and development.
Across the country, roads, public buildings, factories, housing projects and military facilities were being planned. The armed forces, which had expanded considerably during and after the civil war, also required additional accommodation.
All of these projects had one basic requirement.
Cement.
Nigeria produced cement domestically, but local production was insufficient for the scale of construction being contemplated. Imports were therefore necessary.
The problem began when the government’s legitimate need for cement was transformed into a procurement programme far beyond the country’s ability to receive and distribute the material.
By early 1975, the Federal Military Government had entered into an extraordinary number of cement contracts with foreign suppliers.
The United States Court of Appeals for the Second Circuit later recorded that Nigeria had executed 109 contracts with 68 suppliers, committing itself to more than 16 million metric tons of cement at a total value approaching US$1 billion.
The scale of the orders was extraordinary even by the standards of a country experiencing an oil boom.
And there was an immediate problem.
The cement had to enter through Nigerian ports.
The principal destination was Lagos.
Lagos Was Not Built for What Was Coming
The Lagos and Apapa port complex was Nigeria’s principal gateway for international trade. But its facilities had never been designed to receive anything close to the volume of cement that the government had contracted to purchase.
The problem becomes clearer when the figures are placed beside one another.
Before the crisis, Nigeria had been importing roughly two million tons of cement a year through all its ports, according to the account later given by Lord Denning in the English Court of Appeal.
The new orders were many times larger.
The British court described government departments as having ordered about 20 million tons for delivery within twelve months.
The American court record used a different figure for the contracts before it, recording more than 16 million metric tons to be delivered within eighteen months.
Both figures belong to the historical record because they describe the procurement programme from different legal and documentary perspectives. The 16 million ton figure is firmly established in the later United States litigation as the quantity covered by the contracts, while the 20 million ton figure appears in contemporary judicial descriptions of the broader government ordering programme.
Whatever figure is used, the underlying problem was the same.
Nigeria had ordered vastly more cement than its ports could handle.
The Ships Started Arriving
The cement was purchased from suppliers around the world.
Contracts were made.
Letters of credit were opened.
Suppliers arranged for cement to be obtained and shipped.
Ships were chartered.
Cargoes were loaded.
And then the vessels began arriving at Lagos.
The port could not cope.
By July 1975, the waters outside Lagos and Apapa had become crowded with vessels waiting to discharge their cargoes.
Lord Denning’s judgment in the later Trendtex Trading Corporation Ltd v Central Bank of Nigeria recorded that between 300 and 400 ships were waiting outside the port, with more arriving daily. Most were carrying cement.
The United States Court of Appeals later gave an even more specific figure, recording that the harbour contained more than 400 ships, of which approximately 260 were carrying cement.
This is where the famous figure of 400 ships comes from.
It does not mean that exactly 400 vessels were permanently anchored in Lagos at one moment. The number changed as vessels arrived, departed or were redirected. Contemporary judicial records describe the number at different moments as 300 to 400 and more than 400.
But the spectacle itself was real.
Hundreds of ships were waiting outside Lagos.
Many were carrying cement.
And they could not unload.
Lagos Harbour Becomes a Queue
Every ship waiting outside the port created another financial problem.
Ships are not normally expected to remain idle for weeks or months. Their owners expect them to load, sail, discharge their cargo and move on to another assignment.
When a vessel is detained beyond the period allowed under its contract, the owner can charge demurrage, a form of compensation for the delay.
The cement ships were therefore costing Nigeria money even while their cargo remained undischarged.
The longer they waited, the larger the bill became.
And the situation was becoming worse because additional ships were still being dispatched towards Nigeria.
A ship arrived.
There was no berth.
It waited.
Another ship arrived.
It waited too.
Meanwhile, the government was still responsible for the contractual obligations associated with the cargoes.
The result was a maritime traffic jam on an extraordinary scale.
The Crisis Spreads Beyond Cement
The consequences did not stop with the cement industry.
Lagos was the country’s major port gateway, and the port had to handle much more than cement.
Food, machinery, industrial materials, consumer goods and other imports also needed to pass through the same facilities.
The cement ships occupied berths and port resources while other vessels waited.
The congestion therefore began affecting the wider Nigerian economy.
What had started as a procurement decision had become a national logistics crisis.
Nigeria had the money to purchase the cement.
It did not have the infrastructure to receive it.
That distinction would become one of the defining lessons of the affair.
Why Was So Much Cement Ordered?
The enormous purchases did not arise from a completely imaginary need.
Nigeria was genuinely undergoing rapid development.
The Federal Military Government had ambitious plans for infrastructure, while the Ministry of Defence was pursuing military construction projects.
A major part of the cement programme was connected with the construction and development of military facilities.
The later Belgore Tribunal examined the Ministry of Defence’s requirements and the contracts that followed.
Evidence associated with the inquiry indicated that the armed forces’ construction programme had required considerably less cement than the quantity eventually contracted for.
Later accounts of the tribunal’s findings put the Ministry of Defence’s actual requirement at approximately 2.9 million metric tons, compared with contracts for about 16 million metric tons.
The reported cost difference was equally striking.
The requirement of roughly 2.9 million tons was estimated at about N52 million, while the much larger quantity was contracted for approximately N557 million.
The figures became central to the scandal because they suggested that the problem was not simply a case of poor forecasting.
There were serious questions about how the contracts had been negotiated, why such quantities had been ordered and who stood to benefit.
The Price of the Cement
The contracts themselves attracted further scrutiny.
The historical record shows that Nigeria entered agreements with numerous foreign suppliers and trading companies.
Some contracts involved cement prices that were significantly higher than prevailing international market prices.
The tribunal examined the prices, intermediaries and officials involved in the transactions.
This was important because the scandal had now moved beyond the question of why Lagos was full of ships.
The more serious question became:
How had Nigeria ended up buying so much cement, at such prices, through so many contracts?
The answer became the subject of a government investigation after the change of power in 1975.
The Belgore Tribunal
The Federal Military Government established a tribunal headed by Justice B. M. Belgore to investigate the massive importation of cement by the Ministry of Defence.
The tribunal began public sittings in Lagos on 20 October 1975.
It heard evidence from numerous witnesses and examined a substantial body of documentary evidence concerning the contracts and their administration.
The inquiry examined officials, agents and representatives connected with the cement transactions.
The Nigeria Year Book 1976 recorded that by 31 October 1975, the tribunal had ordered 64 agents and representatives of companies involved in cement agreements to appear before it.
The inquiry was not a small administrative exercise.
It was an investigation into one of the largest procurement controversies the country had yet experienced.
What the Investigation Revealed
The investigation brought attention to the extraordinary gap between the cement required for the Ministry of Defence’s construction plans and the quantity actually contracted for.
The reported figures were stark.
The Ministry’s construction requirements were placed at approximately 2.9 million metric tons.
The contracts associated with the scandal involved roughly 16 million metric tons.
The reported cost of the required quantity was about N52 million.
The larger contracts were valued at approximately N557 million.
The findings became one of the strongest symbols of the corruption and administrative disorder that the new Murtala government claimed it was determined to confront.
The investigation also drew attention to officials within the Ministry of Defence, the Central Bank and other parts of the government machinery involved in the transactions.
The tribunal’s work therefore transformed the Cement Armada from a port disaster into a national political scandal.
Nigeria Tries to Stop the Ships
While the investigation was taking place, the government had to deal with the immediate problem at Lagos.
On 9 August 1975, the Nigerian Ports Authority issued Government Notice No. 1434.
From 18 August, vessels intending to sail for Lagos and Apapa were required to provide advance information about their expected arrival. The Nigerian Ports Authority was given responsibility for coordinating shipping movements and could refuse service to vessels that failed to comply.
The measure was an attempt to prevent the congestion from becoming even worse.
But the government went further.
On 18 August 1975, Nigeria instructed its cement suppliers to stop sending cement and to stop loading or chartering additional ships for the Nigerian trade.
The government was effectively trying to shut the door after the flood had already entered.
The Letters of Credit Become the Next Battlefield
The cement contracts had been financed through letters of credit.
This meant that banks became central to the dispute.
As the crisis deepened, the Central Bank of Nigeria instructed its correspondent bank in New York, Morgan Guaranty Trust Company, not to make payments under the letters of credit unless additional approval was obtained.
The change was significant.
Foreign suppliers had already entered contracts, purchased or arranged cement and chartered ships based on the financial arrangements established by Nigeria.
Now the Nigerian government was attempting to prevent payment.
The dispute consequently moved from Lagos Harbour to international banking and commercial courts.
The Ships Were Costing Nigeria More Every Day
The financial problem created by the waiting vessels was enormous.
One documented contract involving Etablissement Esefka International Anstalt concerned 240,000 metric tons of cement at a contract price of US$59.90 per metric ton.
The contract was worth more than US$14 million.
Its associated shipping arrangements also generated demurrage claims when the vessels could not discharge their cargoes.
In another documented case, a demurrage rate of approximately US$3,500 per vessel per day became the subject of litigation.
The cost depended on the particular contract and circumstances, but the principle was devastating.
Nigeria was paying for cargo it could not efficiently receive while also facing claims for the time ships spent waiting to unload it.
The Government Tightens the Embargo
The government eventually formalised restrictions on ships entering Nigerian ports.
On 19 December 1975, Nigeria promulgated Decree No. 40, which prohibited the entry of vessels into Nigerian ports without the required prior approval and imposed criminal penalties for unauthorised entry.
The decree demonstrated how far the crisis had escalated.
What had begun as a commercial procurement programme had reached the point where the government had to regulate the movement of foreign ships into its ports by decree.
The Cement Crisis Enters the Courts
The foreign suppliers did not simply accept Nigeria’s refusal to pay.
They went to court.
Cases relating to the cement contracts appeared before courts in Britain and the United States.
One of the most important was TrendAtex Trading Corporation Ltd v Central Bank of Nigeria.
The case concerned Nigeria’s attempt to rely on sovereign immunity in resisting legal proceedings connected with the cement transaction.
The English Court of Appeal ruled in 1977 that the Central Bank could not use sovereign immunity to escape the proceedings in the circumstances before the court.
The judgment also preserved one of the clearest contemporary descriptions of the Cement Armada.
Lord Denning recorded the extraordinary sight of 300 to 400 ships waiting outside Lagos and explained that the port had been overwhelmed because government departments had ordered far more cement than the country’s ports could handle.
The cement crisis had now become a landmark dispute in international commercial law.
The American Litigation
The legal consequences continued in the United States.
In Texas Trading & Milling Corporation v Federal Republic of Nigeria, the United States Court of Appeals for the Second Circuit considered claims arising from several of the cement contracts.
The court’s 1981 judgment recorded the scale of the programme.
Nigeria had entered 109 contracts with 68 suppliers.
The total quantity exceeded 16 million metric tons.
The value approached US$1 billion.
The court rejected Nigeria’s attempt to rely on sovereign immunity in the cases before it.
The decision was subsequently left standing when the United States Supreme Court declined to review it.
Another case, Verlinden B.V. v Central Bank of Nigeria, eventually reached the United States Supreme Court in 1983.
The case arose from the Nigerian cement transactions and became significant in the development of American law concerning lawsuits against foreign states and their instrumentalities.
The Cement Armada had therefore outlived the government that created the contracts.
Some Ships Eventually Unloaded
The story did not end with every vessel remaining indefinitely outside Lagos.
Some cargoes were eventually discharged.
Others were affected by negotiations, contract settlements, liens, diversions and continuing disputes.
One later American case provides a detailed example.
The company National American Corporation had a cement contract involving several vessels.
The first six vessels connected with its contract carried a combined 37,630 tons. Nigeria completed payment for those cargoes by September 1975, although the vessels had not necessarily been unloaded at the time of payment.
Four of those six vessels were eventually unloaded in Lagos.
Two departed without discharging their cargoes.
Other vessels connected with the transaction never completed their intended journey to Nigeria before the government’s restrictions took effect.
The episode demonstrates how uneven the eventual resolution became.
There was no single moment when the entire Cement Armada simply disappeared.
Different ships, suppliers and contracts were dealt with at different times.
The Cost Continued After the Ships Left
The physical congestion eventually eased, but the financial and legal consequences remained.
Nigeria faced claims for unpaid cement, demurrage and contractual damages.
Suppliers challenged the government’s actions.
Banks became involved.
Shipowners asserted rights over cargoes and claims for unpaid freight or demurrage.
Courts in different countries examined the contracts and the government’s attempt to halt payments.
The crisis therefore continued long after the most dramatic images of ships outside Lagos had disappeared.
A Procurement Disaster Becomes a Symbol
The Cement Armada became one of the most enduring symbols of Nigeria’s oil boom.
The country had suddenly acquired vast financial resources.
The government wanted rapid development.
There was a genuine shortage of cement.
Foreign companies were ready to supply it.
But procurement was not properly matched with infrastructure.
The port could not absorb the volume.
The financial system was tied to international contracts.
And the government eventually found itself trying to stop the very transactions it had authorised.
The result was an extraordinary chain of events.
A construction programme produced massive cement orders.
The orders produced hundreds of ships.
The ships overwhelmed Lagos.
The congestion produced demurrage.
The financial disputes produced lawsuits.
The political transition produced an investigation.
And the investigation turned the cement purchases into a national scandal.
What Happened to the Cement Armada?
There was no single day on which the Cement Armada ended.
The crisis was dismantled gradually.
Nigeria restricted new shipments.
Ships were prevented from entering without approval.
Some vessels unloaded.
Some departed without discharging their cargoes.
Some cargoes became subject to liens.
Some contracts were renegotiated.
Some suppliers went to court.
Others pursued settlements.
The legal disputes continued into the late 1970s and early 1980s.
The United States Supreme Court’s 1983 decision in Verlinden B.V. v Central Bank of Nigeria was one of the later major legal consequences of the original cement transactions.
The episode had therefore become much larger than the port congestion that first brought it to public attention.
The People Behind the Crisis
The Cement Armada involved far more people than the military government at the centre of the story.
Government ministries initiated and administered the purchases.
The Ministry of Defence was particularly important because of its construction requirements.
The Central Bank of Nigeria played a major role in financing the contracts through letters of credit.
The Nigerian Ports Authority had to manage the resulting shipping congestion.
Foreign cement manufacturers and trading companies entered the contracts.
Shipowners and charterers transported the cargo.
International banks handled payments.
Lawyers and courts in several countries eventually became involved.
And at the centre of the political aftermath was the new military administration of Murtala Mohammed, which turned the affair into part of its wider campaign to investigate the conduct of the previous government.
Why the Story Still Matters
The Cement Armada is remembered because its central image is almost unbelievable.
Hundreds of ships.
Millions of tons of cement.
A major African port unable to unload the cargo.
Bills accumulating while vessels waited.
And a government eventually fighting some of the contracts it had authorised.
But the deeper significance of the episode lies in what it revealed about Nigeria in the oil boom.
The country had money.
It had ambitious plans.
It had urgent construction needs.
What it lacked was sufficient coordination between those plans and the systems required to execute them.
The crisis demonstrated that a country could not simply spend its way into development.
Ports had to be capable of handling imports.
Roads and railways had to move cargo away from the ports.
Warehouses had to receive it.
Contracts had to be carefully negotiated.
Financial institutions had to protect public funds.
Government agencies had to communicate.
And procurement had to correspond with genuine requirements.
When those elements failed simultaneously, the result was not development.
It was congestion.
The Historical Legacy
The Cement Armada left several lasting legacies.
Its first was political.
The scandal became part of the wider record of corruption and administrative failures associated with the final period of the Gowon government. After the July 1975 coup, the Murtala administration launched investigations into the previous government’s handling of public resources, and the cement contracts became one of the most prominent cases.
Its second legacy was financial.
Nigeria was left facing substantial claims arising from cement contracts, letters of credit, shipping and demurrage. The disputes tied the country to international litigation for years.
Its third legacy was legal.
The cases arising from the cement contracts became important decisions in British and American law concerning sovereign immunity and the responsibility of foreign governments and their agencies when engaging in commercial transactions.
Its fourth legacy was infrastructural.
The episode demonstrated the vulnerability of Nigeria’s dependence on Lagos as the country’s principal maritime gateway and reinforced the need for expanded port facilities.
Most importantly, the Cement Armada entered Nigerian historical memory as a warning about the consequences of spending on a scale that physical infrastructure and administrative systems cannot support.
The Ships That Became a National Metaphor
The waters outside Lagos in 1975 carried more than cement.
They carried evidence of a country undergoing a dramatic transformation.
Nigeria was richer than it had ever been.
Its government wanted to build.
Its military wanted new facilities.
Its construction industry needed materials.
Foreign companies wanted access to a booming market.
But the systems connecting all those ambitions were not ready for what was coming.
The result was a line of ships stretching across the waters of Lagos and Apapa, waiting for berths that did not exist.
The Cement Armada was therefore not simply a story about an excess of cement.
It was the story of what happened when a development ambition moved faster than the institutions responsible for delivering it.
The ships eventually disappeared from the waters.
The contracts did not disappear so easily.
The tribunal’s investigation became part of Nigeria’s history.
The court cases became part of international legal history.
And the phrase Cement Armada survived as one of the most memorable descriptions of Nigeria’s turbulent oil boom years.
Author’s Note
The Cement Armada remains one of the clearest historical reminders of the extraordinary contradictions of Nigeria’s oil boom era. Nigeria genuinely needed cement for its expanding construction and military programmes, but the government committed itself to quantities far beyond what its ports could receive, turning Lagos Harbour into a vast waiting area for hundreds of ships. The resulting congestion produced enormous demurrage claims, disrupted other imports, triggered a government investigation and eventually generated years of international litigation. What began as an attempt to accelerate national development became a costly lesson in procurement, infrastructure, financial responsibility and public administration.
