implement any accords. The Betancur administration in turn criticized the M-19's actions and questioned its commitment to the peace process, while at the same time continuing to advance high-profile negotiations with the FARC. These negotiations led to the creation of the Patriotic Union (Unión Patriótica) -UP-, a legal and non-clandestine political organization. On November 6, 1985, the M-19 stormed the Colombian Palace of Justice and held the Supreme Court magistrates hostage, intending to put President Betancur on trial. The military responded with force and in the ensuing crossfire some 120 people lost their lives, including most of the guerrillas (several high-ranking operatives among them) and 12 Supreme Court Judges. Both sides blamed each other for the bloodbath, which marked the end of Betancur's peace process. Meanwhile, individual FARC members initially joined the UP leadership in representation of the guerrilla command, though most of the guerrilla's chiefs and militiamen did not demobilize nor disarm, as that was not a requirement of the process at that point in time. Tension soon significantly increased, as both sides began to accuse each other of not respecting the cease-fire. According to historian Daniel Pecáut, the creation of the Patriotic Union took the guerrillas' political message to a wider public outside of the traditional communist spheres of influence and led to local electoral victories in regions such as Urabá and Antioquia, with their mayoral candidates winning 23 municipalities and their congressional ones gaining 14 seats (five in the Senate, nine in the lower Chamber) in 1988. According to journalist Steven Dudley, who interviewed ex-FARC as well as former members of the UP and the Communist Party, FARC leader Jacobo Arenas insisted to his subordinates that the UP's creation did not mean that the group would lay down its arms; neither did it imply a rejection of the Seventh Conference's military strategy. Pecáut states that new recruits entered the guerrilla army and its urban militia units during this period, and that the FARC continued to carry out kidnappings and to target regional politicians for assassination. In October 1987 Jaime Pardo Leal, who had been the UP's presidential candidate the previous year, was assassinated amid a wave of violence in which thousands of the party's members perished at the hands of death squads. According to Pecáut, the killers included members of the military and the political class who had opposed Betancur's peace process and considered the UP to
