On 29 July 1966, a group of officers, including Majors Murtala Muhammed, Theophilus Yakubu Danjuma, and Martin Adamu, led the majority Northern soldiers in a mutiny that later developed into a "Counter-Coup" or "July Rematch". The coup failed in the South-Eastern part of Nigeria where Ojukwu was the military Governor, due to the effort of the brigade commander and hesitation of northern officers stationed in the region (partly due to the mutiny leaders in the East being Northern whilst being surrounded by a large Eastern population).
