Mola emerged as the chief planner
among the plotters. While General
José Sanjurjo, in exile in Portugal, remained the recognized leader, Mola was delegated the authority within the organization to plan operations in Spain. Known as "the Director", Mola sent secret instructions to the various military units to be involved in the uprising and worked out a detailed plan for a post-coup government. In a memorandum dated 5 June 1936, Mola envisioned a "republican dictatorship" based on the Portuguese model. The initial government would consist of a "directory" that would oversee a semi-pluralist but authoritarian state. According to Mola: "The Directory will guarantee no change in the republican regime during its administration, with no change in any worker claims that have been legally obtained" but would "create a strong and disciplined state". The 1931 constitution would be suspended and new elections would be held. Certain liberal elements, such as separation of church and state and freedom of worship, were to be maintained. Agrarian issues were to be resolved by regional commissions with the aim of developing small holdings, but allowing for collective cultivation in some circumstances. Despite extensive planning, Mola apparently doubted the chances for the coup's success. His dim view of the capabilities of monarchist militias and the conservative Catholic party
Spanish Confederation of the Autonomous Right (CEDA), as well as only limited support from the
Falange, led him as late as 9 July to consider the possibility of having to flee to France if it failed. After several delays, 18 July 1936 was chosen as the date of the coup.
Francisco Franco's participation was not confirmed until early July. Although events ran ahead of schedule in the
Spanish Protectorate of Morocco, Mola waited until 19 July to proclaim the revolt. When Mola's brother was captured by the Republicans in Barcelona, the government threatened his life. Mola replied: "No, he knows how to die as an officer. I can neither take back my word to my followers and probably you cannot either from yours." The brother ended up committing suicide. Mola then ordered systematic executions in captured cities to instill fear. More than 40,000 were killed, overseen by Mola. He famously declared: The
Nationalist coup failed to gain control of Madrid and other urban areas, although most of the armed forces had supported it. As the situation devolved into civil war, Sanjurjo was killed in an air crash on 20 July. Mola then became Nationalist commander in the north, while Franco became commander in the south. With the death of Sanjurjo, Mola established a multi-member governing body for the so-called "Nationalist zone" () called the
National Defense Junta. Based in Burgos, it was nominally headed by
Miguel Cabanellas, the most senior participating general. On 5 September a
Nationalist offensive sent by General Mola under Colonel
Alfonso Beorlegui took
Irún and closed the French border. Mola's forces went on to secure the whole of the province of
Guipúzcoa, isolating the remaining Republican provinces in the north. A
junta in
Burgos proved unable to set overall strategy; thus, Franco was chosen commander-in-chief at a meeting of ranking generals on 21 September. Mola continued to command the Army of the North and led an unsuccessful effort to take
Madrid in October. In a radio address, he described Nationalist sympathizers in the city as a "
fifth column" that supplemented his four military columns. The Republican government then proceeded to carry out the mass execution of as many as 2,000 suspected civilian and military supporters of the Nationalists. What was later known as the
Paracuellos massacres crushed any potential fifth column. ==Death==
