By 1793 the convento had been expanded until its ground floor extended around the four sides of the present well courtyard (Old Spanish Missions Historic Research Library [OSMHRL], Mission San Jose, San Antonio, Texas, missions microfilm roll 4). The second floor of the west side continued around the southwest corner and along the south side of the patio. The one-story section along the north side was only partially roofed, the east side was nothing but bare walls.
The church itself remained unfinished and in virtually the same condition from at least 1772. The decorative facade was finished only to a height of about 25 ft; from the description it looked virtually the same in 1793 as it does today. No towers had been built, although the bases for the towers were present (Eaton 1980:Figure 6). The apse, at the east end of the church, was the only portion with any vaulting. The remainder of the church had the arches to support the dome and the vaulting of the nave and transepts, but not all these were finished. Since the mission was secularized in 1793, no further work was done. Subsequent stories about the church being full of rubble from its fallen vaults and towers are not altogether true; undoubtedly, some rubble would have been present had one or more of the arches fallen, but this would have consisted only of scattered cut stone blocks.
In the north courtyard the building which is now the north half of the Long Barracks was built as a granary before 1745 but had served in the 1740s as the church. In 1793 this building contained the equipment usually found in a granary, such as a large sieve and several measures of various sizes; but the roof was being replaced or was incomplete, so a nearby jacal was being used as a temporary granary (OSMHRL, microfilm roll 4). Next to the granary, within the present courtyard, were several other rooms of the workshop complex, which had been in use throughout the years 17451793 (OSMHRL, microfilm roll 4). The cloth-making workshop was apparently directly east of and adjoining the granary, but the locations of the other workshop rooms within the courtyard are uncertain. They were likely placed along the walls of the courtyard rather than in its central areas, but no descriptions of any such walls along the north or east sides of the courtyard have yet been found.
In 1793 San Antonio de Valero was secularized (Habig 1977:66), and the property outside the walls was divided among the mission Indians and a group of refugees from the Presidio los Adaes and its associated missions in east Texas, which had been closed in 1772. The property within the walls of the mission remained nominally in the hands of the Catholic church, although the Spanish government exercised considerable control over it. In about 1803, the Segunda Compañía Volante de San Carlos de Parras del Alamo, a company of Spanish Cavalry, was assigned to San Antonio and posted to the mission grounds in the barracks. They occupied the mission intermittently from 1803 until about 1825 (Habig 1977:71).
Little is presently known about changes to the Alamo buildings introduced by the Compañía Volante. The available evidence indicates they were probably housed in the old Indian quarters. That the structure along the south side
