On 16 July 1949, Arana delivered an ultimatum to Arévalo, demanding the expulsion of all of Árbenz' supporters from the cabinet and the military; he threatened a coup if his demands were not met. Arévalo informed Árbenz and other progressive leaders of the ultimatum, who all agreed that Arana should be exiled. A secret meeting of the permanent committee of the congress met and voted to dismiss Arana. Cuban President Carlos Prío Socarrás agreed to give Arana asylum there. Two days later, Arévalo and Arana had another meeting, at which Arévalo later said that Arana was highly threatening and abusive. On the way back, Arana's convoy was intercepted by a small force led by Árbenz. A shootout ensued, killing three men, including Arana. Arana's supporters in the military rose up in revolt, but they were leaderless, and by the next day the rebels asked for negotiations. The coup attempt left approximately 150 dead and 200 wounded. Many of Arana's supporters, including Carlos Castillo Armas, were exiled. The details of the incident were not made public.
