Owerri 1969: The 16th Brigade’s Breakout From Encirclement


 In his fine book “Epic Retreats – From 1776 to the Evacuation of Saigon”, Stephen Tanner analyses retreat under pressure in seven military campaigns. They are General George Washington’s retreat from New York in 1776 during the American revolution, Napoleon’s retreat from Russia in 1812, and the great retreat of the Nez Perce Indians of the American West in 1877.  Others are the evacuation of British expeditionary troops from Dunkirk in 1940, retrograde operations of the 1st Panzer army in the Caucasus in 1942, and the harrowing retreat of the American 8th Army from the Pusan perimeter in Korea in late 1950.  Lastly, he reviewed the chaotic evacuation of Saigon in 1975 by American forces retreating from Vietnam.  


However, the specific accounts of fighting withdrawals discussed in Tanner’s excellent book are by no means the only great examples from which serious students of military history can draw lessons.  In my humble opinion, two specific examples of breakouts from encirclement deserve particular emphasis.  They are:

1.  The breakout of General W. J. Slim’s Burma Corps from Japanese encirclement at Rangoon and 900 mile retreat to Imphal (in India) under pressure in 1942.

2.   The break out of the 1st US Marine Division under Brigadier General Lewis B. “Chesty” Puller from Chinese encirclement at the Chosin reservoir, under sub-arctic conditions in mountainous terrain during the Korean War, between November 27th and December 9th, 1950.

It is with these accounts, among others at the back of my mind, that I now return to the subject of this essay.

Choices open to the 16th Brigade at Owerri

Faced with encirclement, the 16th Brigade had a number of choices:  
First, they could continue their attack northwards, deep along the original axes hoping to attain the initial grand objectives of ‘Operation OAU’ and relieve their sister Brigades in the process.  As noted previously, this option was briefly pursued and then terminated.

Secondly, they could hold their position in Owerri and environs and defend encircled, as they did for many months.  This was based not only on their original operational orders in September 1968 but also the direction of AHQ, confirmed by a “stand and fight” radio signal from the C-in-C, Major General Gowon himself in February 1969.   It did seem that higher national pride (not to mention the need to maintain the aura of the 3MCDO and protect Colonel Adekunle’s image) was involved in the decision not to allow Owerri to be abandoned.   Military factors in favor of this option included the built in advantage of defending an urban area, equipped with armored vehicles (which the besieging Biafrans did not have).    These vehicles included Saracen Armoured Personnel Carriers, Ferret and Saladin Armored cars, which gave Etuk a fire power and mobility advantage using “interior lines” for rapid support by force transfer from his core support area of all round front-line positions in the “hedgehog”. In any case, if and when he had to break out he could rupture the encirclement by sheer armored force.  In support of this optimistic thinking was the initial assumption that the Brigade could be supported by air, reinforced and relieved before certain destruction by the Biafran armed forces.   The absence of Biafran air power and the curious initial Biafran strategy of attacking with one infantry Brigade at a time from only one direction in a sequential manner rather than a simultaneous all round assault encouraged such thinking.  All Etuk had to do was “jab” with his front-line infantry positions and support artillery before delivering a powerful “counter-punch” using armored vehicles concentrated on the attacking force at the point of threatened penetration. The last factor that gave Etuk initial confidence was the federal effort to para-drop supplies, supported by occasional strafing and bombing of Biafran positions by NAF L-29, Mig-17 and Ilyushin fighter jets and bombers. 

However, the Biafrans soon settled in for an alternative strategy. In between infantry assaults, harassing artillery fire and long range snipers gradually reduced the 16th Brigade by continuous external pressure through attrition.  This approach enabled the besieging Biafran units to conserve men and perhaps redeploy them for emergencies in other fronts.  But it had the disadvantage of using up a lot of ammunition in an endless orgy of repeated bombardments, which, although murderous and highly effective, were ultimately insufficient to compel Etuk to surrender.  It also allowed the siege to drag on.  The “penetration” attempt by Colonel Achuzia failed because it used only one frontal axis.  Eventually, 14 Division Commander, Colonel Ogbugo Kalu, supported by Major General Madiebo, armed with intimate knowledge of Etuk’s hopeless situation, correctly chose to attack, penetrate and exploit along multiple converging axes with little fear that Etuk – desperately short of men and supplies - could inflict punishment in retaliation.  This combination of fire and maneuver eventually forced Etuk to choose between surrender, displacement, or complete destruction.  When that point was reached, then Lt. Col. EA Etuk, with the support of his second-in-command, Major AT Hamman, decided they would ignore the suicidal orders of the 3MCDO HQ and AHQ to “hold until relieved.”  They decided they would either break out or exfiltrate to the rear, in the direction of friendly 3MCDO forces.

Indeed, Biafran sources are of the opinion that Etuk considered this line of action at least three times. Two of these occurred in March when he first realized encirclement was total on or about March 7th, and then later in the month had to beat back ferocious efforts by the “S” Division to penetrate and divide his forces.   Russian and German forces often did this to encircled enemy units during WW2.   However, on each occasion impatient Biafran units rushed into the Owerri pocket in frontal pursuit to take advantage, only to be badly beaten back when Etuk suddenly reconfigured his armor for counter-attack.

There is some evidence that Biafran units used the technique of selective reduction of strong points.  On February 10th, for example, Ojukwu claims that 500 Russian automatic rifles and 100 boxes of ammunition were secured from one of the 16th Brigade’s defensive positions.  Madiebo does not, however, make any comment that such a vast haul of weapons was secured.  In any case, organized systematic selective reduction targeted at large groups of key battlefield assets did not occur.   This would have involved choosing one of Etuk’s main ‘teeth’ arm detachments, such as armor, for example, (or artillery) and then destroying that first (as a whole) before focusing on other combat and combat support elements. One reason was that Etuk usually withdrew his armored vehicles back into center of the Owerri pocket after using them for a counter-attack.  He never left them open.  The other reason was the shortage of appropriate anti-tank weaponry.  It does, however, seem that there were efforts at reduction by infiltration which involved penetrating the perimeter with small commando units designed to isolate small elements of the 16th brigade from their parent unit.  

During pauses between attacks, such as was the case when Ojukwu called off Achuzia’s penetration attack, Biafran Commanders supported their attrition strategy with continuous reconnaissance probes and psychological operations (psyops).  Examples of psyops include the case of the female Captain who regularly showed up in full view of federal troops to hail “Biafra Kwenu” and the choice of nighttime to do most of the shelling of federal positions in Owerri.  In addition, inadvertently routing the final approach to over-fly Owerri of early morning relief aircraft bringing ammunition to Uli-Ihiala airstrip before daybreak sent an unmistakable message to the besieged forces.   They also had to live with the knowledge that most of the federal para-dropped ammunition and food meant for them were going to their tormentors.   They even had to fight for the little they got!  Then there were the sniper shots, slowly but surely killing all the leadership figures in the Brigade.  All of this was backed up by electronic measures such as federal communications interception.   On the flip side, Ojukwu visited Biafran units besieging Owerri at least twice in the month of March, raising morale and getting involved in tactical decisions.

Relevant developments outside Owerri
On the federal side and international front, other developments ultimately impacted the Owerri situation.    At the February meeting in Lagos of divisional commanders mentioned earlier, a semblance of coordination was urged.  But deep mistrust and rivalry remained.  Colonel Adekunle, for example, did not tell his fellow divisional commanders (ie Colonels Shuwa and Ibrahim Haruna) in the 1st and 2nd divisions the full extent of his Owerri dilemma.  Instead, the meeting focused on resolving the question of which Division would be given the task of taking Umuahia, following Adekunle’s disaster in October 1968 when he tried doing so on his own to beat Shuwa to it and end the war.

Therefore, rather than instructing the 1st Division to relieve the 16th Brigade directly by attacking Owerri from Okigwe which is 30 miles away (as the crow flies) in the north-easterly direction, Shuwa was told to veer southwest to take Umuahia, then administrative capital of Biafra. This clarified an old dispute with Adekunle but did not directly address the Owerri situation.  In retrospect, although Umuahia was highly significant, if Shuwa had successfully attacked Owerri (rather than Umuahia) in early 1969, in coordination with a southern assault on Owerri from Port Harcourt by 3MCDO, both divisions would have relieved the beleaguered 16th Brigade. They would also have divided Biafra into two, separating the Biafran capital at Umuahia from its resupply airfield at Uli-Ihiala in the west.  Chances are that the war – with its horrendous losses - may have been shorter. 

The fall of Umuahia to the 1st Division will be discussed in detail in a future essay.  In summary, Colonel Shuwa tasked the commanders of 1 and 2 Sectors (later called Brigades) of the 1st Division to take Umuahia and Bende respectively.  Under the command of 1 Sector Commander, Lt. Col. ADS Wya, the plan for the fall of Umuahia – code-named Operation Leopard - was drawn up by his Brigade Major, Major Abdullahi Shelleng and the Sector Deputy Assistant Quartermaster General  (DAQMG), Major Mamman Jiya Vatsa. 

Meanwhile, the other brigades of Adekunle’s 3MCDO division had reorganized and recaptured Mkpom, Usung-Ubum, Ikot-Abia and Ikot Obom on February 3rd, followed on March 20th and 27th by the recapture of Umudike and Aba Ala earlier lost in the Biafran counter-offensive of 1968.  The Colonel General Staff at 3MCDO HQ at this time was Major George Innih while Lt. Col. Emmanuel Abisoye, a former 2 Sector Commander with the 1st Division, was in charge of 3MCDO (rear) in Lagos, securing supplies for front-line units “by any means necessary”.

On March 27, 1969, with the support of a squadron of armoured vehicles under Captain Garba Duba, 11 Field Squadron of Nigerian Army Engineers under Captain Gida Inakusu, “Q” Battery of Nigerian Army Artillery under Captain AB Mamman, and 1 Field Ambulance, five infantry battalions launched the assault on Umuahia.  These battalions, namely the 4th, 21st, 25th, 44th, and 82nd were commanded by Major Ado Mohammed (later replaced by Lt. Steve Samaila Yombe), Major YY Kure, Lt. Balarabe Haladu, Major IB Babangida (later replaced by Major MJ Vatsa) and Major Ibrahim Bako respectively.  NAF fighter-bombers later assisted in close air-support although there were a few unfortunate incidents of deadly ‘NAF friendly fire’ at Abriba and Uzuakoli.

A Zambian delegation had visited Biafra from March 13 – 15 followed two weeks later by the British PM’s visit to Nigeria.  When the objective of ‘Operation Leopard’ became evident, Ojukwu started desperately mobilizing soldiers and resources from all corners of what remained of Biafra (including Owerri) to save Umuahia, eventually stalling but not stopping Col. ADS Wya’s advance in two weeks of fierce fighting.  During the time, nevertheless, Ezi Alayi, Ovim, Amoyi, Ndi Ihube, Uzuakoli, Isikwuato, Umuokorola and Bende fell to the 1stDivision, while elements of the 3rd MCDO took back Umuomayi and Okuenyi on April 4th. This was followed by the recapture of Obetete on April 5th which had been lost only 24 hours earlier.  On April 13th, 3MCDO lost Obokwe again, typical of its extremely labile situation since October 1968. 

Biafra’s final offensive to retake Owerri 
Beginning with his visit to Uzuakoli, followed by the precautionary evacuation of the Biafran government from Umuahia to Nkwerre, near Orlu on April 4th up until the fall of Bende on April 14th, Ojukwu became increasingly concerned about the fate of Umuahia, where his bunker was located.  According to Madiebo:

“By the 14th of April, it had become obvious judging from the situation on the ground, that Umuahia was going to be lost.   It was also clear that such an event would destroy completely the will of the Biafran people to continue the war.  It was then that Colonel Ojukwu told me of the need to revive the Owerri operation on the off-chance that we might score a victory there to counter-balance the loss of Umuahia.  The idea was to share the few resources available into two to try and clear what was left of Owerri before it was too late.  The whole idea was a calculated risk worth taking if the Head of State who alone knew what ammunition the nation had, thought so.
On the 18th of April, therefore, the Owerri operations were reopened.  As I was still at Umuahia, I did not know exactly what was available for the offensive.  However, the plan of the operation which was sent to me for approval, showed that the 60 Brigade was again to clear the right side of the town up to the Clock Tower and including the Holy Ghost College, the Catholic Cathedral and the Progress Hotel.  The 52 Brigade, now under Major Igweze, was to have another go at Orji and the northern part of the town, down to the Public Works Department and the Government Secondary School.  Elements of “S” Division under command of 14 Division in the absence of Onwuatuegwu, who was still at Umuahia, had the task of advancing through Egbu and Nekede into Owerri, as far as to the motor park.”

Far away in Monrovia, Liberia, the OAU consultative committee was meeting on April 17th.  No one knew that history was about to be made on an African battlefield.    Remnants of the 16th Brigade of the 3MCDO that had held Owerri since September 16, 1968 and was at least partially cut off for almost six months since November 1st, and totally besieged since March 14th, were about to break out.  Etuk was finally persuaded not just by Biafra’s equally historic final offensive to retake Owerri, an act that in turn had been prompted by the impending fall of Umuahia to federal units under Col. ADS Wya, but by what transpired inside Owerri on April 19th. 

April 19th, 1968: The Final DC-3 overflight and death of Major A Ted Hamman
On April 19th, Captain Francis Mokonogho and his DC-3 crew lifted off from Port Harcourt airport for yet another routine tactical airdrop over Owerri.  But, unknown to them, fate beckoned.  They flew right into a Biafran offensive.  Biafran anti-aircraft gunners were no longer in the mood to accept the free aerial gifts from the federal government, nor were they going to allow Etuk the luxury of any more ammunition or food, no matter how small.  Thus, they shot at the plane furiously, forcing Mokonogho to abort its final approach and turn around to Port Harcourt with its cargo.  He barely made it back.  The DC-3 was badly riddled with bullet holes.  It would be the last attempt by the 3MCDO to resupply its beleaguered brigade. 

Back in Owerri, Etuk, now at his wit’s end, was faced with the penetration of Biafran units, so close in one axis that they were nearly upon his HQ.  He called his trusted second in command (2iC) and Brigade Major (Hamman) aside for urgent consultations.   They agreed – without reference to 3MCDO HQ or AHQ - that a last ditch effort to breakout towards the rear with all they had was only the only credible option.  Surrender was out of the question.

As of this time, the surviving troops of the 16th brigade had acquired the “thousand yard stare.”  As described by a survivor of the American break out from the Chosin reservoir in Korea, the stare results from a combination of tiredness, sleeplessness, and fear, combined, paradoxically, with a strong will to survive.  When men get into that condition, they are fighting for no one but themselves and their buddies, not any country or imaginary ideal.  For many months, the Brigade had endured chronic sleep deprivation, repeated mortar and 105mm artillery barrages, short, but repeated violent firefights back and forth in and out of foxholes and buildings with shot guns, rifles and machine guns.  Practically every building in the town had been destroyed.  Then there were the deaths of numerous colleagues, impromptu burials, personal injuries, near death experiences, rain, hunger, cold, heat, insect bites, separation from family, the emotional highs and lows of relief over-flights and DC-3 air drops, the stench, and worst of all, a suspicion that they had been abandoned. 

 According to Colonel Etuk (rtd),

“My decision to withdraw wasn’t proper. The Army Headquarters should [ordinarily] give me the go-ahead but I did [without authority] and said let me be court-martialled when I am out with my troops.  [If] I didn’t do that, it would have meant complete elimination of the whole troops and that was what Ojukwu was waiting to do. If not through hunger it would have been through torture by whatever means he chose to use. But the Army Headquarters did little or nothing to get me as a Brigade Commander out of that place. What sort of battle organization is that?  So I said to myself, ‘When I come out let them put me on trial.’  But they didn’t do it; maybe they knew that that was the only way to save the few lives I was able to…..”

“…..the rebels had penetrated into the town where my headquarters was situated and so the firing was so close; as we are sitting here you will just hear deafening sounds. One should not stay at a position for too long for the time may turn out to be enough for the enemy to kill you….”

“So one Sunday morning, when the rebels were almost at my headquarters and we were doing nothing because there was nothing we could do then – no ammunition, the men were gone, no weapons – I called the attention of others and said to them: 

“We have to pull out of this place to see what we can do next week to save a few lives remaining”

So we set out towards Emmanuel College.  We were all determined to get out of the place, be it a cook, a washerman; in fact, every one of us with or without a weapon.  As we left, within 30 minutes after the decision, I heard a cry,

“Oga, come oh! Oga come oh!  Dem don kill Oga oh!”

Behold, he was shot right there.  The man was gasping for breath. He had a very large wound. If the road had been opened and if we had immediate medical attention, possibly his life might have been saved.   There weren’t even drugs. The doctor I had was just sitting and watching while the man died. 

“…before the poor boy died, he [Major Hamman] said,

“Oga, Allah, Allah, if I see Adekunle I will finish him. Adekunle is the man that has caused this.”

I said, “Well, we cannot say, but all we should be thinking is to be able to leave this place if it is possible.”

Coming as it did at the tail end of the siege, after a preliminary decision had been made to plan a break out, the death of the competent and popular Major Ted Hamman was absolutely devastating for unit morale.  It stretched the cohesion of the unit to the limit and sorely tested the command and leadership skills of Etuk.  The next day, April 20, 1969, Ojukwu made an entry in his diary, documenting the Biafran interception of weak federal radio transmissions from Owerri alerting 3MCDO HQ of Major AT Hamman’s death.  However, 3MCDO HQ did not notify AHQ of the development.  For the Biafran side, Hamman’s death was a signal that before long the 16th brigade might simply collapse.

Meanwhile, according to Colonel Etuk (rtd):
“The death of that young man forced me to take a decision of praying to God that if He is the God that delivered the children of Israel from Egypt then He should deliver my troops.  Of course, God delivered us.”
