In June, Franco was contacted and a secret meeting was held within the forest of La Esperanza on Tenerife to discuss starting a military coup. An obelisk commemorating this historic meeting was erected at the site in a clearing at Las Raíces.
On 12 June, Prime Minister Casares Quiroga met General Juan Yagüe, who falsely convinced Casares of his loyalty to the republic. Mola began serious planning in the spring. Franco was a key player because of his prestige as a former director of the military academy and as the man who suppressed the Asturian miners' strike of 1934. He was respected in the Army of Africa, the Army's toughest troops. He wrote a cryptic letter to Casares on 23 June, suggesting that the military was disloyal, but could be restrained if he were put in charge. Casares did nothing, failing to arrest or buy off Franco.
