Iliya Bisalla and the 1976 coup trials occupy an important place in Nigeria’s political and military history. Major General Iliya D. Bisalla was serving as Federal Commissioner for Defence when General Murtala Ramat Muhammed was assassinated during an attempted military takeover on 13 February 1976.
Less than one month later, Bisalla was convicted by a Special Military Tribunal and executed by firing squad in Lagos. The Federal Military Government accused him of occupying a senior position within the conspiracy associated with Lieutenant Colonel Bukar Suka Dimka.
Bisalla’s prosecution was particularly significant because of his position in government. He was not a junior officer operating outside the military establishment. He was a former divisional commander, a former Commandant of the Nigerian Defence Academy and the official responsible for defence matters within Murtala Muhammed’s administration.
His fall from senior office to execution reflected the severity with which Nigeria’s military leadership responded to the assassination of the Head of State and the attempted overthrow of the government.
Bisalla’s Rise Through the Nigerian Army
Bisalla belonged to the generation of Nigerian officers who received military training during the final years of British colonial rule. He attended the Royal Military Academy Sandhurst before rising through the ranks of the Nigerian Army.
During the Nigerian Civil War, he commanded the Nigerian Army’s 1st Division. By January 1970, he was publicly identified as the division’s commander as federal forces advanced into the remaining territory controlled by the Republic of Biafra.

The civil war ended on 15 January 1970 after the Biafran leadership surrendered to the Federal Military Government. Bisalla remained an important figure in the army during the post-war period.
He later became Commandant of the Nigerian Defence Academy in Kaduna. The academy was responsible for training officer cadets for service in the Nigerian armed forces.
Following the overthrow of General Yakubu Gowon on 29 July 1975, Murtala Muhammed became Head of State. Bisalla was appointed Federal Commissioner for Defence in the new government.
The office broadly performed the political functions associated with a defence minister. Operational command of the army rested with the Chief of Army Staff, Lieutenant General Theophilus Danjuma, while Bisalla served as a senior member of the government responsible for defence administration and policy.
The Assassination of Murtala Muhammed
On the morning of 13 February 1976, Murtala Muhammed left his residence for work in Lagos. His car travelled without a large military escort, reflecting his preference for a relatively simple security arrangement.
Soldiers involved in the coup ambushed his vehicle near the Federal Secretariat in Ikoyi. Muhammed, his aide-de-camp, Lieutenant Akintunde Akinsehinwa, and his driver were killed.
Other coup participants moved against senior government figures and strategic locations. Lieutenant Colonel Bukar Suka Dimka entered the Nigerian Broadcasting Corporation premises and announced that the government had been overthrown.
In his broadcast, Dimka accused the government of corruption, indecision, arresting innocent people and pursuing policies that threatened the country. He declared that the military administration had been removed and attempted to present the coup as a nationwide takeover.
The announcement did not produce the support the plotters needed. Senior commanders and major military formations refused to join the coup. Loyal troops regained control of the broadcasting station and other important locations in Lagos.
The coup collapsed within hours.
Obasanjo Takes Control of the Government
Lieutenant General Olusegun Obasanjo was Chief of Staff at Supreme Headquarters when Muhammed was assassinated. He assumed leadership of the government and became Nigeria’s Head of State.
The new administration continued the policies and transition programme introduced under Muhammed. At the same time, the government began a major investigation into the coup.
Military officers, policemen and civilians suspected of involvement were arrested. Investigative panels questioned suspects and examined the organisation, objectives and leadership of the conspiracy.
Dimka escaped from Lagos after the coup failed. Security forces searched for him across the country before he was captured on 5 March 1976.
By the time of Dimka’s arrest, the first group of suspects had already been investigated and brought before a Special Military Tribunal.
The Case Presented Against Bisalla
The Federal Military Government accused Bisalla of playing a directing role in the conspiracy.
On 12 March 1976, Brigadier Shehu Musa Yar’Adua, the Chief of Staff at Supreme Headquarters, presented the government’s account of the attempted coup to journalists.
The government stated that dissatisfied officers had begun planning to overthrow the administration. It also alleged that Bisalla had been involved with another group of senior and middle-ranking officers before contact was established between the two groups.
According to the official account, Bisalla opposed parts of the government’s military policies, including decisions involving promotions and the proposed reduction of the armed forces.
The authorities alleged that Bisalla instructed Dimka to begin detailed operational discussions with other officers. He was also accused of selecting 13 February as the date for the takeover and assigning responsibility for operations in different parts of the country.
The government further alleged that the conspirators planned to kill senior members of the administration. The named targets included Murtala Muhammed, Olusegun Obasanjo, Theophilus Danjuma, Shehu Yar’Adua and Ibrahim Babangida.
These allegations placed Bisalla at the senior political level of the conspiracy, while Dimka and other officers were associated with its operational execution.
The Special Military Tribunal
The accused were tried by a Special Military Tribunal rather than an ordinary civilian court.
The tribunal operated under the authority of the Federal Military Government. Investigative panels examined the cases before the defendants were brought before the military tribunal.
The tribunal convicted Bisalla and other defendants of offences connected with the attempted coup. Their sentences were reviewed and confirmed by the Supreme Military Council.
The process moved rapidly. Murtala Muhammed was assassinated on 13 February, and Bisalla was executed on 11 March, only 27 days later.
The use of a military tribunal reflected the political system operating in Nigeria at the time. The country was governed by military decrees, and the armed forces exercised legislative, executive and judicial authority in matters regarded as threats to the state.
The Executions of 11 March 1976
Bisalla was executed by firing squad at Kirikiri Prison in Lagos on 11 March 1976.
He was among the first group of people condemned in connection with the coup. Contemporary accounts reported that 30 people were executed that day, while the government announced 32 death sentences following the first phase of the proceedings.
Those executed included military officers and civilians accused of taking part in the conspiracy or assisting the plotters.
The executions were intended to demonstrate the government’s determination to punish those connected with the assassination and attempted takeover.
Dimka was not included in the March group. He had been captured only six days earlier and was questioned during a later stage of the investigation.
Joseph Gomwalk, the former military governor of Benue-Plateau State, was also tried during the later phase.
Dimka and Gomwalk Executed in May
Dimka was brought before the Special Military Tribunal after his capture. The authorities accused him of leading the operational phase of the coup, making the radio announcement and participating in the attempt to overthrow the government.
Joseph Gomwalk was accused of involvement in the wider conspiracy. Gomwalk had served as military governor of Benue-Plateau State from 1967 until 1975.
On 15 May 1976, Dimka, Gomwalk and five other convicted defendants were executed by firing squad in Lagos.
The five others were Colonel Isa Bukar, Major J. K. Afolabi, Lieutenant S. Kwale, Warrant Officer II E. Bawa and police officer H. Shaiyen.
The May executions marked the final major round of death sentences arising from the coup. Other defendants received life imprisonment or shorter prison terms, while some suspects were released.
Bisalla, Dimka and Gomwalk therefore faced execution in two separate phases. Bisalla died on 11 March, while Dimka, Gomwalk and five others were executed on 15 May.
The Political Impact of Bisalla’s Conviction
Bisalla’s conviction sent a powerful message through the Nigerian armed forces. A serving Federal Commissioner for Defence had been accused of joining a conspiracy against the government in which he held office.
His rank and previous commands made the case more significant than the prosecution of a junior officer. Bisalla had served at the highest levels of the army and government.
The coup also led to changes within the armed forces. Officers suspected of disloyalty were investigated, dismissed, imprisoned or executed. The government strengthened internal security and placed greater attention on the political activities of military personnel.
Murtala Muhammed’s death also transformed his public image. His brief period as Head of State, combined with the circumstances of his assassination, made him one of the most widely remembered leaders in Nigerian history.
Obasanjo remained Head of State until 1979. His administration continued the transition to civilian rule and transferred power to President Shehu Shagari on 1 October 1979.
Bisalla’s Place in Nigerian History
Bisalla is remembered principally for his conviction and execution following the failed coup. His earlier military career, including his Civil War command and leadership of the Nigerian Defence Academy, has often been overshadowed by the events of 1976.
His case illustrates the instability that characterised Nigeria’s early years of military government. Between January 1966 and February 1976, the country experienced several coups, attempted coups, political assassinations, a civil war and repeated changes of national leadership.

Military officers operated not only as soldiers, but also as governors, commissioners, ministers and heads of government. Political disagreements within the armed forces could therefore become direct threats to the state.
The failed coup of February 1976 demonstrated the danger of this arrangement. The assassination of the Head of State was carried out by soldiers, and the government’s response was controlled by military institutions.
Conclusion
Iliya Bisalla and the 1976 coup trials remain central to the history of Nigeria’s military era.
Bisalla rose through the Nigerian Army, commanded the 1st Division, led the Nigerian Defence Academy and became Federal Commissioner for Defence under Murtala Muhammed.
After Muhammed’s assassination on 13 February 1976, the Federal Military Government accused Bisalla of helping to organise the conspiracy. The authorities alleged that he selected the date of the coup, directed operational planning and identified senior government figures as targets.
A Special Military Tribunal convicted him. He was executed in Lagos on 11 March 1976.
Dimka, Joseph Gomwalk and five others were tried during a later phase and executed on 15 May.
The case remains one of the most dramatic examples of the relationship between military power, political loyalty and justice in post-independence Nigeria. Bisalla’s rise and sudden fall reflected an era in which senior officers could move rapidly from national leadership to imprisonment and execution.
Author’s Note
The life and death of Iliya Bisalla reveal the instability of an era when Nigeria’s armed forces controlled both the government and the institutions responsible for judging threats against it. His career shows how military distinction could lead to national power, while his execution demonstrates how quickly that power could disappear during a political crisis. The lasting lesson of the 1976 coup is that national security, lawful government and public trust depend on institutions capable of surviving political conflict without becoming instruments of fear or revenge.
