The January 1966 coup marked a turning point in Nigeria’s history, toppling elected officials and placing the military at the centre of national governance. Three senior officers Major-General Johnson Aguiyi-Ironsi, Brigadier Samuel Ademulegun, and Brigadier Babafemi Ogundipe found themselves navigating unprecedented challenges. Their actions, decisions, and fates shaped the country’s trajectory for years to come.
Ironsi: The Army Commander Who Took Control
Major-General Johnson Aguiyi-Ironsi was the General Officer Commanding of the Nigerian Army at the time of the coup. When the coup erupted, several senior officers and political leaders were assassinated, creating a power vacuum. Ironsi, as the highest-ranking officer, assumed control to restore order. He became the Head of State and Supreme Commander of the Armed Forces, leading a military government that sought to stabilise the country.

Ironsi later introduced Decree No. 34, which replaced the federal system with a unitary government. While intended to streamline governance, it sparked suspicion among northern officers and heightened ethnic tensions, setting the stage for the counter-coup of July 1966.
Ademulegun: The Senior Officer Who Paid the Ultimate Price
Brigadier Samuel Ademulegun commanded the 1st Brigade in Kaduna. On the night of 15 January 1966, mutineers entered his residence and killed him along with his pregnant wife. Historical accounts indicate that Ademulegun questioned the coup plotters and refused to cooperate, reflecting loyalty to the existing chain of command. His death symbolised the vulnerability of senior officers during the uprising and intensified the sense of betrayal felt within the army.
Ogundipe: The Second-in-Command Who Stayed Out of Politics
Brigadier Babafemi Ogundipe served as Chief of Staff, Supreme Headquarters under Ironsi. Following the coup, he played an administrative and coordinating role within the military government but did not claim the position of Head of State. His seniority made him a natural candidate, yet he lacked the support of northern officers and the loyalty of troops, making any attempt to lead untenable. Ogundipe later served as Nigeria’s High Commissioner to the United Kingdom after the July counter-coup.

Impact of Their Actions on Nigeria
The different paths taken by these three officers illustrate the stakes of leadership during crisis. Ironsi’s decision to assume power ensured immediate stability but also fuelled ethnic distrust. Ademulegun’s death highlighted the human cost of the coup and the fragility of military loyalty. Ogundipe’s restraint reflected the limits of authority in the absence of political and military backing. Together, their experiences shaped Nigeria’s early military era and the patterns of governance that followed.
Author’s Note
The January 1966 coup was a defining moment in Nigeria’s history, with far-reaching consequences for the nation’s politics and military. This account shows that leadership, loyalty, and survival were tested under extreme circumstances. Ironsi stepped in to maintain order, Ademulegun remained loyal to command and lost his life, while Ogundipe chose administrative continuity over political ambition. Their stories reveal how decisions in moments of crisis can shape a nation’s destiny, highlighting both the fragility of institutions and the profound responsibility carried by those in power.
