In the spring of 1838 France blockaded the coast of Mexico during the Pastry War, so-called because of the mistreatment of french citizens, including pastry chefs, living in Mexico. The strategic location of Corpus Christi Bay led to the revival of smuggling in this area. Supplies were carried overland across the Rio Grande, and the illicit trade flourished as Mexico bought sorely needed goods in Texas. Although president Sam Houston did not wish to antagonize Mexico, Mexican patrols at Corpus Christi offended many Texans.
In July, 1838, authorities at Texana heard reports of Mexican activity near the bay. A captured Mexican sea captain said that his government had declared Corpus Christi a port of entry and had dispatched about 400 men to protect it. A summons was issued, calling Texans to rally at Texana, August 7, to drive the invaders from the republic's boundaries.
By the time the volunteers reached the area, some of the Mexicans had landed their supplies near the tip of Corpus Christi Bay and returned to Matamoros. The rest scattered, leaving about 100 barrels of flour and parts of a steam engine. The Texans confiscated the usable flour, and other contraband, and the site became known as Flour Bluff.
