After the return to civilian rule, by-elections were held (beginning in autumn 1968) and an all-APC cabinet was appointed. Calm was not completely restored. In November 1968, unrest in the provinces led Stevens to declare a state of emergency across the country. Many senior officers in the Sierra Leone Army were greatly disappointed with Stevens' policies and his handling of the Sierra Leone Military, but none could confront Stevens. Brigadier General Bangura, who had reinstated Stevens as Prime Minister, was widely considered the only person who could control Stevens. The army was devoted to Bangura, and this made him potentially dangerous to Stevens. In January 1970, Bangura was arrested and charged with conspiracy and plotting to commit a coup against the Stevens government. After a trial that lasted a few months, Bangura was convicted and sentenced to death. On 29 March 1970, Brigadier Bangura was executed by hanging in Freetown.
