The Civil guards took the ground floor of the telephone building, but were prevented from taking the upper levels. Soon, trucks carrying armed anarchists arrived. CNT councilors demanded the removal of police commissioner Rodríguez Salas, but Lluís Companys refused. The POUM stood by the CNT and advised them to take control of the city, but the CNT appealed to the workers to cease fighting. With the situation deteriorating, a meeting of CNT delegates from Valencia and the Generalitat under Companys agreed on a ceasefire and a new provisional government, but despite of this, the fighting continued. Dissenting anarchists such as the "Friends of Durruti" and radical members of the POUM along with Bolshevik Leninists spread propaganda to continue to the fighting. On Wednesday, 5 May, prime minister Largo Caballero, under constant pressure from the PSUC to take control of public order in Catalonia, appointed Colonel Antonio Escobar of the Republican Guard as delegate of public order, but on his arrival in Barcelona, Escobar was shot and seriously wounded. After constant appeals by the CNT, POUM and UGT for a ceasefire, the fighting abated on the morning of 6 May. In the evening, news reached Barcelona that 1,500 assault guards were approaching the city. The CNT agreed on a truce after negotiations with the minister of interior back in Valencia. They agreed that the assault guards would not be attacked as long as they refrained from violence and that the CNT would order its members to abandon the barricades and go back to work. On 7 May, the assault guards entered Barcelona unopposed, and soon there were twelve thousand government troops in the city.
