Implication and Conviction in the abortive February 1976 Coup Attempt
General Bisalla was implicated by Colonel Dimka's confessional statements after investigations into the abortive 13 February 1976 Dimka led coup which resulted in General Mohammed's assassination. Bisalla was controversially convicted of conspiracy and concealment of treason by the secret Special Military Tribunal; and as a result, Bisalla's complicity is not clear (e.g., the Federal Military Government (FMG) asserted that Bisalla gave Dimka operational orders while Dimka, under interrogation, stated that another officer (Major Rabo) provided the operational orders).[3] Importantly, Dimka's confessional was not corroborated and Dimka was known to have provided inconsistent testimonies and drank beer while being interrogated.[3]
Death
General Bisalla along with 31 other alleged co-conspirators some clearly guilty (such as Colonel Dimka and Lt. William Seri) and others whose guilt remain questionable (such as Joseph Gomwalk) were executed by firing squad on 11 March 1976.[4]
