In 1834 he was elected the first alcalde of Matagorda and wrote the Goliad Declaration of Independence, signed on December 22, 1835. During the Texas Revolution Ingram participated in the capture of Goliad as commissary and secretary to commandant Philip Dimmitt. In November 1835 he requested a transfer from Stephen F. Austin. He served in Capt. Thomas Stewart's company of Matagorda Volunteers in 1836. On April 5, 1836, Gen. Sam Houston ordered Ingram, then commissioned as a major, to return to East Texas and the United States to recruit volunteers for the Texas army. Ingram was Matagorda representative in the First Congress of the Republic of Texas and was elected speaker of the House. He resigned from the legislature on May 1, 1837, possibly because of the disclosure that he had once been convicted of forgery and imprisoned in New York. He was again elected mayor of Matagorda, but died on September 22, 1837, before his inauguration. Ingram was present at the first meeting of the Masonic fraternity in Texas on January 11, 1828. In his will he left $70,000 to the Matagorda schools.
