For years, the war announced itself after sunset at Uli. Aircraft came in low and unlit, engines throttled back, touching the ground only long enough to unload food, medicine, and limited supplies before disappearing again into the darkness. These landings were brief, risky, and irregular, but they became a familiar rhythm for those nearby. They were proof that Biafra, despite blockade and isolation, still had a connection to the outside world.
In January 1970, that rhythm ended. The aircraft stopped coming. The silence that followed was not merely the absence of sound. It was the clearest sign yet that the war was reaching its conclusion.

By the opening days of the year, the Biafran enclave had been reduced to a narrow and increasingly indefensible pocket of territory. Years of blockade and sustained fighting had drained resources and manpower. Civilians and soldiers endured the same shortages, the same hunger, and the same uncertainty. Supplies were critically low, movement was dangerous, and survival depended less on strategy than endurance. It was into this exhausted landscape that the Nigerian federal military launched its final campaign.
A War Compressed to Its Final Space
The offensive, officially designated Operation Tail Wind, began on January 7, 1970. Its objective was no longer containment or pressure, but closure. Federal commanders sought to end the conflict by seizing Biafra’s remaining strongholds and eliminating the final routes that sustained resistance.
The plan relied on speed, coordination, and overwhelming force. Nigerian troops advanced in a pincer formation, converging from multiple directions to compress what remained of Biafran-held territory. The intention was clear: deny withdrawal, prevent regrouping, and leave no room for prolonged resistance.
Operation Tail Wind was led by the Third Marine Commando Division under Colonel Olusegun Obasanjo. By this stage of the war, the balance of power had shifted decisively. Federal forces held clear advantages in manpower, equipment, and logistics. Biafran units, weakened by prolonged isolation, faced the offensive with dwindling ammunition and almost no prospect of reinforcement. The disparity shaped the tempo of the campaign and the speed with which events unfolded.
The Pincer Closes
Federal troops pressed forward from the north, south, and east, denying Biafran forces the ability to stabilise new defensive lines. Towns that had endured earlier phases of the war now faced coordinated assaults from several fronts at once. The strategy avoided drawn-out engagements. Instead, it aimed to overwhelm quickly, leaving defenders no time to adapt to each loss before the next followed.
On January 9, Owerri fell. For months, the town had been one of the most prominent symbols of Biafran resistance, surviving repeated attempts to dislodge its defenders. Its capture marked more than the loss of territory. It signalled that the remaining defences could no longer hold. For civilians in surrounding areas, the fall of Owerri brought further displacement and fear, although detailed civilian accounts from these final days remain limited in surviving records.
Uli and the End of the Lifeline
Two days later, on January 11, federal troops captured Uli. This moment proved decisive. The airstrip was not simply a military objective. It was Biafra’s last operational link to the outside world, the narrow passage through which aid and supplies had continued to arrive despite the blockade.
With the capture of Uli, that connection was severed entirely. There would be no further landings, no additional supplies, and no realistic means of sustaining resistance. The loss carried immediate military consequences and a profound psychological impact. For years, the airstrip had sustained not only material survival but belief. Its fall made defeat unavoidable.
Collapse of Leadership and Authority
Soon after the fall of Uli, Chukwuemeka Odumegwu Ojukwu left Biafra for exile. The available material does not fully document the circumstances of his departure, but its significance was unmistakable. Leadership passed to his deputy, Major General Philip Effiong, at a moment when the space for decision had all but disappeared.
By January 13, 1970, Effiong formally surrendered to Nigeria’s Head of State, General Yakubu Gowon. With that act, the Nigerian Civil War came to an end. The surrender was not the result of negotiations conducted from a position of balance. It was the final outcome of exhaustion, isolation, and overwhelming military pressure.
Why the Final Offensive Succeeded
Operation Tail Wind succeeded where earlier campaigns had stalled because it exploited conditions that had been developing for years. Biafra was already economically and militarily drained by blockade. Its forces suffered acute shortages of food, ammunition, and equipment. Nigeria’s ability to apply superior resources at multiple points simultaneously closed off every remaining alternative.
Speed proved as decisive as strength. The rapid fall of Owerri and Uli denied Biafran commanders the time needed to adjust or recover. Once Ojukwu departed, the symbolic centre of resistance collapsed as well. In the final days, resistance faded quickly. Whether this reflected formal orders, physical impossibility, or cumulative exhaustion is not fully established in the surviving documentation.
The War’s Quiet End
The conflict that ended in January 1970 had been defined by prolonged stalemate, intense fighting, and widespread suffering under blockade and famine. Its conclusion came not through a single climactic battle, but through a final convergence of forces that closed every remaining gap.
When the fighting stopped, Nigeria emerged territorially intact, but profoundly changed. Authority had been reasserted through force. Communities had been displaced. The social and political fabric of the country had been permanently altered.
The silence over Uli after January 11 was not simply the absence of aircraft. It was the quiet confirmation that the war had finished speaking, leaving a nation to live with what had been decided in those final days.

Author’s Note
This article traces how Operation Tail Wind brought the Nigerian Civil War to its conclusion by capturing Owerri and Uli, severing Biafra’s final lifeline, and forcing surrender through exhaustion and isolation. It highlights how the war ended not in negotiation, but through a decisive military convergence that reshaped Nigeria’s postwar reality.
