Statue of Padre J. Nicolas Balli Located on South Padre Island. Historical Marker on base reads: "Padre Island, off the South Texas coast, is named for Padre Jose Nicolas Balli (177?-1829), whose family migrated from Spain in 1569 and became large landowners in the Lower Rio Grande Valley. In 1800 Balli applied to King Charles IV of Spain for 11 1/2 leagues of land on the island, and in 1804 started its first settlement, Rancho Santa Cruz. Padre Balli served as collector of finances for all the churches in the Rio Grande Valley and founded the first mission in present Cameron County. Padre Balli's ministry was a great influence on the lives of early South Texas settlers."

Barrett commanded Federal troops on Brazos Island 12 miles to the east. The Confederates occupied Fort Brown 12 miles to the west, commanded by Gen. James E. Slaughter and Col. John S.

Photograph of Historical Marker entitled: "Site of Camp Belknap." Text reads: "In May 1846 when war was declared against Mexico, the U.S. Congress authorized the raising of 50,000 volunteer troops to supplement the regular U.S. Army. General Zachary Taylor was quickly inundated with volunteer soldiers arriving at Brazos Santiago, and was forced to place them in temporary encampments. Camp Belknap, located on this site, was established in the summer of 1846. The camp was located on a long narrow rise of land, measuring about 2 miles in length and one-half mile at its widest point. It was the first high ground encountered after leaving the Gulf Coast. Thought to be the largest encampment for volunteer soldiers, troop estimates total 7,000-8,000 men including several regiments from eight states. Soldiers suffered exposure to the elements, unsanitary living conditions, overcrowding, biting insects, thorny plants, and disease. Many died a premature death, often resulting in one two two funerals daily. No enemy attacks took place despite one false alarm. During August and September most of the volunteers were moved upriver either to camps nearer Matamoros, or further to Camargo. The camp was completely empty by December 1846."
