Ladies led by Clara Driscoll supported a plan emphasizing the Texas revolutionary period, with the church as the principal structure.
Governor Oscar B. Colquitt also favored a full-scale restoration of the convento and cancelled the order granting custody of the Alamo property to the DRT. The proposal to reconstruct the convento was abandoned when the lieutenant governor engineered the removal of the structure's second story during one of Colquitt's absences from the state.
