The tussle between Samir Geagea and Elie Hobeika for control over the Lebanese Forces had started as early as March 1985. That same month, Samir Geagea gained control over the LF after defeating the last leader of the Phalangist militia, Fouad Abou Nader. In May of that same year, however, Elie Hobeika was appointed to lead that unit. In December 1985, Hobeika signed in the name of the LF an agreement with the Syrian government, the DruzeProgressive Socialist Party led by Walid Jumblatt, and the Shia MuslimAmal Movement headed by Nabih Berri, which became known as the Tripartite Accord. One of the cornerstones of the agreement was the disbandment of Lebanese militia forces. It also provided for initiating political changes that would end Christian dominance of the Lebanese parliament and army. There was a dispute over whether to retain links with Israel and how to react to Syrian-sponsored negotiations to end the fighting. Hobeika broke LF links with Israel and supported the negotiations between the LF, the Lebanese government, Syria, and Druze leaders such as Walid Jumblatt. Geagea opposed the negotiations which he claimed would make unacceptable concessions to Syria and weaken the Lebanese Christian community's political power. In October 1985, with negotiations in progress, skirmishes took place between Geagea's supporters and Hobeika's supporters, where hobeika's supporters tried to bribe geagea's supporter's to betray Geagea. In December 1985, a peace agreement, the Tripartite Accord, was reached. It was signed by Hobeika for the LF, but the LF Command Council was split, with only half agreeing with the deal. In addition, the agreement was criticized by the former President of LebanonCamille Chamoun and leader of the predominately Christian MaroniteNational Liberal Party, and by some Maronite Church leaders because they felt that this agreement was one sided favoring the muslim communities in lebanon.
The coup
Samir Geagea and president Amine Gemayel decided not to accept the agreement, with Geagea's LF faction attacking Hobeika's LF Loyalists' positions in east Beirut on 8 January 1986, being backed by the Lebanese Army's 9th Brigade. On 13 January, in a bid to greatly extend Hobeika's own power, his faction stepped up the conflict by assaulting the positions held by the Kataeb Party militia loyal to Amine Gemayel. The Kataeb party leader, Amine Gemayel, was at the time serving as president of Lebanon. The support of the Kataeb to the pro-Geagea LF faction during the conflict that ensued proved decisive in the defeat of Hobeika, resulting in his ousting from the command of the LF, which was subsequently taken over by the victorious Geagea. The defeated Hobeika escaped from east Beirut in a helicopter and made his way to the town of Zahle in the Syrian-controlled Beqaa Valley, where he rallied his remaining supporters to form the dissident Lebanese Forces – Executive Command militia sponsored by Syria. Later, Geagea attacked the Kataeb that supported him and started a consolidation of power campaign which resulted in crippling the Kataeb. with Dany Chamoun of the NLP and Leila Hawi, east Beirut, late 1980s.
