Lt S. E. Idowu, service number N/359, belonged to a generation of Nigerian Army officers whose careers unfolded during the turbulent first years after independence. Commissioned as a second lieutenant in 1963, he served with the 2nd Battalion and was promoted to substantive lieutenant shortly before the July 1966 counter-coup.
Later family-linked accounts identify him as Stephen Ekundayo Idowu. A photograph associated with his family describes him on his wedding day in 1959, years before Nigeria entered the political and military crises that would transform both the country and its armed forces.
By the end of July 1966, Idowu’s battalion at Ikeja had become one of the centres of a violent military revolt. The upheaval that swept through Nigerian Army formations on 29 July cost the lives of numerous officers and soldiers and brought an abrupt end to Idowu’s military career.
Lt S. E. Idowu and His Early Army Career
The Federal Republic of Nigeria Official Gazette of 30 May 1963 recorded Officer Cadet S. E. Idowu among those granted Combatant Short Service Commissions.
He received the rank of second lieutenant with effect from 27 April 1963, with seniority dating from September 1962. His Nigerian Army personal number was N/359.
An Army listing published in January 1964 placed Second Lieutenant S. E. Idowu, N/359, with the 2nd Battalion.

The battalion would become one of the most important military formations during Nigeria’s political crises of 1966. Stationed at Ikeja in Lagos, it stood close to the centre of events during both the January coup and the counter-coup six months later.
Idowu continued to progress in his military career. The Official Gazette published on 7 July 1966 recorded his promotion to the substantive rank of Lieutenant, effective from 1 May 1966.
The promotion came at a dangerous moment in Nigerian history. Within weeks, tensions that had been growing inside the Army since January erupted into another violent military confrontation.
Nigeria After the January 1966 Coup
Nigeria entered 1966 under civilian government, but the political order created at independence was shattered by the military coup of 15 January.
Senior political leaders and military officers were killed in Lagos, Kaduna and Ibadan, while military operations took place in several other locations.
Among those killed were Prime Minister Sir Abubakar Tafawa Balewa, Northern Region Premier Sir Ahmadu Bello, Western Region Premier Chief Samuel Ladoke Akintola and senior military officers including Brigadier Samuel Ademulegun.
The coup eventually collapsed.
Major-General Johnson Aguiyi-Ironsi, then the most senior Nigerian Army officer, emerged as Head of State after authority passed from the civilian government to the military.
The months that followed were marked by intense political and military tension.
The pattern of the January killings became a major source of resentment, especially in Northern Nigeria. Many Northern political and military figures believed that the coup had disproportionately targeted leaders from their region while several senior Igbo officers and politicians survived.
Within the Army, anger also developed over the treatment of the officers responsible for the January coup.
Aguiyi-Ironsi’s government attempted to reorganise the country, but political suspicion deepened. His introduction of the Unification Decree in May 1966, which replaced Nigeria’s federal administrative structure with a more centralised system, generated strong opposition in parts of the country.
By July, resentment within sections of the armed forces had reached a dangerous level.
The July 1966 Counter-Coup Begins
The military revolt that became known as the July 1966 counter-coup began during the night of 28 July and the early hours of 29 July.
Abeokuta became one of the first major centres of the uprising.
Northern soldiers turned against officers and soldiers they associated with the January coup and the government of Aguiyi-Ironsi. The violence quickly spread beyond Abeokuta.
Military formations in Ikeja, Ibadan, Kaduna, Kano and other areas were affected as command structures began to break down.
The counter-coup combined political objectives with personal grievances, military resentment and ethnic tension. Northern officers and soldiers played the central role in the uprising, while Igbo and other Eastern military personnel became major targets.
The crisis soon reached the 2nd Battalion at Ikeja.
Lt S. E. Idowu and the 2nd Battalion at Ikeja
During the early hours of 29 July, troops connected with the revolt at Abeokuta reached the 2nd Battalion at Ikeja.
Northern soldiers inside the formation seized important positions and gained access to the armoury. The battalion rapidly descended into violence.
Officers and soldiers of Eastern origin were attacked in their quarters and as they arrived for normal military duties.
Several officers connected with the battalion were killed during the upheaval.
Among the casualties associated with the 2nd Battalion were Major Bernard Nnamani, Captain John Chukwueke, Captain Jonathan Egere, Captain Godwin Ugoala, Lieutenant Godson Mbabie and Second Lieutenant Pius Onyeneho.
Lt S. E. Idowu was also killed during the July military violence.
The battalion where he had served since the early part of his career had become one of the principal centres of Nigeria’s second military revolt in six months.
Fighting at Ikeja Barracks
The violence at Ikeja was part of a wider breakdown of military discipline in and around Lagos.
The Nigeria Year Book 1967 described heavy fighting at Ikeja Barracks on 29 July. Sporadic shooting continued into the night as the military authorities struggled to regain control.
Troops moving towards Ikeja encountered resistance around the Maryland area, while uncertainty spread across Lagos.

Emergency measures were introduced, and curfews were imposed in Ikeja, Ibadan and Abeokuta.
The crisis extended far beyond the barracks.
Communication between military formations became uncertain, senior officers struggled to determine who controlled particular units, and the fate of the Head of State remained unclear for several days.
Nigeria had effectively entered another struggle for control of the armed forces and the government.
The Killing of Aguiyi-Ironsi and Fajuyi
While fighting unfolded at Ikeja and other military formations, another major event was taking place in Ibadan.
Major-General Johnson Aguiyi-Ironsi was visiting the Western Region and staying at Government House with the Military Governor of the region, Lieutenant-Colonel Francis Adekunle Fajuyi.
During the counter-coup, soldiers surrounded the residence.
Aguiyi-Ironsi and Fajuyi were taken away and killed.
Their deaths removed both Nigeria’s Head of State and the military governor of one of the country’s most important regions at a moment when the armed forces were already deeply divided.
For several days, uncertainty surrounded the leadership of Nigeria.
On 1 August 1966, Lieutenant-Colonel Yakubu Gowon announced that he had assumed responsibility for the government and the armed forces.
Nigeria had entered another phase of military rule.
The Family Behind Lt S. E. Idowu
Military history often preserves officers through ranks, units and service numbers, but behind N/359 was a husband and father.
Later Nigerian accounts identify his wife as Esther and state that the couple had four children.
The family story places Esther and the children close to the violence surrounding Idowu’s death. It also remembers the intervention of his military orderly during the crisis.
A photograph associated with the family depicts a much earlier period in his life. Described as having been taken on his wedding day in 1959, it presents Idowu before the coups, barracks violence and political instability that would later dominate Nigeria.
The contrast is striking.
The officer remembered through the violence of 1966 had once stood as a newly married young man at the beginning of family life, before Nigeria itself had even become independent.
The Human Cost of the July Counter-Coup
The death of Lt S. E. Idowu formed part of a much larger military tragedy.
Dozens of commissioned officers died during the July and August 1966 violence. Large numbers of non-commissioned officers and ordinary soldiers were also killed.
Eastern military personnel, particularly Igbo officers and soldiers, suffered heavily.
The killings profoundly changed the Nigerian Army.
Trust between officers from different regions deteriorated. Soldiers increasingly viewed military events through regional and ethnic loyalties, while large numbers of Eastern personnel attempted to leave postings elsewhere in Nigeria.
The armed forces, which were supposed to represent a unified national institution, became increasingly fractured.
The consequences reached far beyond military barracks.
From the Counter-Coup to National Crisis
The July counter-coup did not resolve Nigeria’s political problems.
Instead, it deepened them.
Later in 1966, further violence against Easterners occurred in parts of Northern Nigeria. Large numbers of people fled towards the Eastern Region.
Relations between Lieutenant-Colonel Yakubu Gowon’s Federal Military Government and the Eastern Region’s military governor, Lieutenant-Colonel Chukwuemeka Odumegwu Ojukwu, deteriorated.
Efforts were made to reach a political settlement.
Military leaders met at Aburi in Ghana in January 1967, but disagreements subsequently emerged over the interpretation and implementation of the agreement reached there.
The political crisis intensified during the following months.
On 30 May 1967, Ojukwu declared the Eastern Region the independent Republic of Biafra.
The Federal Government rejected the secession.
War began in July 1967.
The military violence in which officers such as Lt S. E. Idowu lost their lives therefore belonged to a chain of events that increasingly divided Nigeria and ultimately contributed to the outbreak of the Nigerian Civil War.

Remembering Lt S. E. Idowu
The career of Lt S. E. Idowu was relatively short.
He entered the commissioned ranks of the Nigerian Army during the early post-independence years, served with the 2nd Battalion and achieved substantive lieutenant rank in 1966.
His career ended during one of the most turbulent moments in Nigerian military history.
The personal number N/359 links the different stages of that career: the officer commissioned in 1963, the second lieutenant serving with the 2nd Battalion in 1964 and the lieutenant promoted shortly before the events of July 1966.
Beyond the military record stands the memory of Stephen Ekundayo Idowu as a husband and father whose life became intertwined with one of Nigeria’s defining political crises.
Conclusion
Lt S. E. Idowu belonged to a generation of Nigerian officers whose military service coincided with the collapse of the country’s First Republic and the rise of military government.
His commission came during the hopeful early years following independence. His promotion came during a period of growing instability. His death followed only weeks later as the July 1966 counter-coup spread into the 2nd Battalion at Ikeja.
The violence of that period would reshape the Nigerian Army, remove Aguiyi-Ironsi from power, bring Yakubu Gowon to national leadership and deepen the political divisions that preceded the Nigerian Civil War.
Idowu’s story gives that turbulent history a human dimension.
Behind the service number N/359 was a young officer whose life, career and family were overtaken by a national crisis that transformed Nigeria.
Author’s Note
The life of Lt S. E. Idowu shows how quickly the ambitions of individuals can become entangled with the crises of a nation. He entered the Army during Nigeria’s early independence years, rose through its ranks and was building both a military career and a family when political divisions reached the barracks themselves. Remembering officers such as Idowu broadens the history of 1966 beyond coups and changes of government, revealing the personal cost carried by soldiers, spouses and children when a national institution fractured from within.
