30 November 1990.  From: http://www.nps.gov/saan/learn/historyculture/espadahistory1.htm

"Spanish Franciscan missionaries pursued a powerful vision for God and country. They aligned and trained the
Coahuiltecan (kwa-weel-teken) hunting and gathering cultures to be servants of God and loyal, productive
citizens of New Spain. Over a 50-year period, they earnestly taught the principles of farming, ranching, architecture,
blacksmithing, loom weaving, spinning, and masonry. Espada was the only San Antonio mission where bricks and
tiles were made. The Catholic faith and Spanish language became the foundation of the new culture."
