 This was due to his enthusiasm when engaging in alliance talks with the Alfonsinos and personal friendship with their leader, José Calvo Sotelo; though new Traditionalist jefe Manuel Fal approached Bloque Nacional as tactical option to be eventually abandoned, Bau was suspected of pushing for a dynastical compromise.In the spring of 1935 Don Alfonso Carlos and Fal considered Bau's activity in the Bloque intolerable and semi-rebellious.Also present-day scholars name his position as "conspiration", while others claim that he was loyal to Calvo rather than to Traditionalism.
