The Abagana Ambush (March 31, 1968) was a military ambush by Biafran guerrilla troops led by Major Jonathan Uchendu that wiped out the Nigerian 2 Division. Of the 6000 Nigerian troops ambushed, only very few survived including General Murtala Muhammad.
On October 4, 1967, the Nigerian 2nd Division began bombarding Onitsha and continued the assault for eight days before a 10 boat armada crossed the Niger River into the city. The occupying Nigerians didn't pursue retreating Biafran soldiers and instead opted to loot and burn the Onitsha market to the ground. The Biafran 11th and 18th Battalions under Maj. Joseph Achuzie and Col. Assam Nsudoh formed a pincer and attacked Onitsha from two directions, capturing and killing most Nigerian soldiers. In December 1967 the Nigerian 2nd Division an 6th Battalion crossed the Niger River at Idah and began making their way towards Onitsha, finally capturing the City after several attempts. The Nigerian Forces now intended to link up the 1st Division at Enugu with the 2nd Division at Onitsha. To this end the Nigerian 2nd Division moves out towards Enugu in a long convoy supported by armored cars on 31 March 1968.
On March 31, 1968, a 106 vehicle convoy of the Nigerian 2nd Division transporting 6000 infantry as well as armor from Onitsha to Enugu was ambushed and decimated in the town of Abagana by a small troop of Biafran soldiers led by Maj. Jonathan Uchendu. Homemade Ogbunigwe rocket missiles were launched by the Biafrans at a tanker truck carrying gasoline which caused an enormous explosion that tossed armored cars like tin cans. 350 tons of equipment were destroyed or captured by the Biafran troops.
The successful ambush at Abagana gave both Biafran soldiers and civilians hope in the war as well as temporarily halting the Nigerian advance into Biafran territory. General Murtala Mohammed was relieved of his command and never commanded a division again.
- Though John de St. Jorre mentions Colonel Joseph Achuzie as commander of the operation, Major-General Alexander Madiebo (General Officer Commanding the Biafran Army) credits Major Uchendu. Chinua Achebe and others also credit Uchendu. From all indications, Achuzie was the commanding officer of Uchendu`s division and strategically planned the operation, while Uchendu led the actual ambush.
- International journalists present in Biafra at the time like Frederick Forsyth, Gilles Caron and other authors give the strength of the ambushed Nigerian troops as 6000 men supported by armor, of which almost all were lost. Chinua Achebe gives the much lower figure of about 500 Nigerian troops. All sources state that the convoy was about 100 vehicles long including troop transport, ammunition transport, tankers and armored cars.
Major Jonathan Uchendu carried out the very attack. His 39 Battalion was an offshoot of 18 Battalion commanded by Col. Nsodor. In his own words, Uchendu said the sight of the convoy almost paralyzed his troops. His boys were so anxious to start firing, more out of panic than anything else. He asked them to remain calm until he gave the command. He allowed many of the Nigerian 2 Div. convoy pass through. His boys were shocked why he would allow them go through into Biafran held zone. They were nervous, suspicious, yet they trusted he military gallantry and so awaited to know his strategy. He said they concluded that the war was over, but as brave soldiers, they must fight to the last!
As he was guiding the soldier (I think a Sergeant) with the rocket launcher on what to do to the invading convoy and when best to strike, the soldier nervously and accidentally pressed the trigger,letting go the rocket! Luckily, he hit a target - a fuel Tanker! The Tanker exploded and threw its contents onto a nearby Armour carrier setting everything ablaze. The multiple explosion commenced! In panic, soldiers who already crossed over into Biafran line ran in different directions in total confusion. Biafran soldiers attacked. They radioed the regular troops and they joined in the attack. When Uchendu learnt that Muritala Mohammed was with the Convoy and somewhere in Nawfia, he set off hurriedly to capture him but was late as Muritala was sighted taking off with a Helicopter!
