The latter lambasted his accord with "ultra-fascist line" of "El Pensamiento Navarro" and his "posición ultramontana"; Gambra mobilized Traditionalists to challenge progressist grip on Carlism and prior to the 1976 Montejurra gathering, which effectively produced fatal casualties, called for "asistencia masiva de los verdaderos tradicionalistas, que alcallará gestos y voces, 'declaraciones' y 'manifiestos', sencillamente inadmisibles, intolerables".
