Campaigning was due to start on 13 April for the second round, until its disruption as a result of the coup d'état. Days before the coup, fellow Lusophone country Angola announced its forces would be ending the two-year-old Angolan Military Mission in Guinea Bissau (MISSANG) that followed a similar failed effort by the European Union as part of the United Nations Integrated Peacebuilding Office in Guinea-Bissau (UNIOGBIS). State-owned Angolan news agency "ANGOP" said that the Angolan troops were sent to Guinea-Bissau in March 2011 in accordance with a bilateral military agreement to reform the armed forces. On 16 April, Guinea-Bissau Defense Minister Jorge Tolentino Araújo was scheduled to arrive in Angola to meet his counterpart Cândido Pereira dos Santos Van-Dúnem and the Army Chief-of-Staff Geraldo Sachipengo Nunda. He was also expected to visit the Higher Warfare School (ESG) and the Higher Technical Military Institute (ISTM). The same day as the coup, the two Lusophone countries of Angola and Cape Verde agreed to review their defense cooperation agreements. Presidential candidate and former Prime Minister Carlos Gomes Júnior was also unpopular with the army for his attempts to reform the institution. According to Portugal's "SIC Notícias", a day before the coup an unidentified military commander claimed Gomes Júnior would allow Angolan troops into the country. He also claimed that soldiers possessed a "secret document" that allowed the Guinea-Bissau government to sanction an Angolan attack on Guinea-Bissau's military. The leaders of the junta released an unsigned communique that read they "did not have ambitions of power" and that the coup was a reaction to the alleged agreement with Angola because the 200 military trainers would "annihilate Guinea-Bissau's armed forces." The spokesman for the junta that took over after the coup, Lieutenant-Colonel Daha Bana na Walna later said that Gomes Júnior and Pereira were ousted because of "unease" in the armed forces over the election, a sentiment echoed by diplomats. Gomes Junior was also viewed as the "candidate of Angola" in the election, according to Chatham House's Africa director Alex Vines. He also said that the months leading up to the events featured media commentary and hostility towards Angola. On 12 April, gunfire was heard between 19:00 and 21:00, as mutinous troops attempted to overthrow the government by seizing control of the centre of the capital Bissau.
