Isaac Ryan was born 1805 in Louisiana. He took part in the Siege of Béxar and served in the Alamo garrison as a member of Capt. Robert White’s infantry company, the Béxar Guards. Ryan died in the battle of the Alamo on March 6, 1836.
Michael Cronican was from Massachusetts. He traveled to Texas as a volunteer in Capt. William G. Cooke’s company of New Orleans Greys in 1835 and fought in the Siege of Béxar, after which he received a furlough as a result of illness and left for New Orleans. His original company was murdered at Goliad during his absence.
William Brenan, soldier and legislator of the Republic of Texas, was born in Ireland. On October 25, 1835, he enlisted as a private in Capt. Samuel O. Pettus’s company of New Orleans Grays. He saw action at the Siege of Béxar and the disastrous battle of Coleto. He survived the infamous Goliad Massacre, however, and was discovered at Goliad by doctors J. H. Barnard and John Shackelford. He thereupon joined Capt. William H. Patton’s company – the so-called Columbia Company – of Col. Sidney Sherman’s Second Regiment, Texas Volunteers, in time to participate in the battle of San Jacinto.
Henry Warnell was born in 1812. In January 1835 he settled in Bastrop, where he lived with and worked for Edward Burleson. Warnell took part in the Siege of Béxar and later served in the Alamo garrison as a member of Capt. William R. Carey’s artillery company. There is some evidence that he escaped from the Alamo during the battle of March 6, 1836, but died in Port Lavaca in June 1836 from wounds received in the battle.
Dr. Joseph E. Field reached Texas in 1833 and lived near Brazoria and Matagorda for two years. Late in 1835, when the Texas Revolution broke out, he was at Gonzales, on his way to Mexico, and he and the four other doctors in the area volunteered their services. Field marched with the army to San Antonio and during and after the Siege of Béxar served as both doctor and soldier. On his way from San Antonio he met Sam Houston, with whom he traveled as far as Nacogdoches. At the Mexican armed incursion in the spring of 1836, Field joined the command of James Walker Fannin, Jr., fought at the battle of Coleto, and was made a prisoner along with Fannin’s other men. He and the other doctors were spared from the Goliad Massacre so that they could treat wounded Mexicans. After two weeks Field made his escape and heard the news of the battle of San Jacinto. After the revolution he made a visit to Massachusetts, where, in September 1836, he published Three Years in Texas. On his return to Texas late that year he joined the army. He died in Clear Water Harbor, Florida, in 1882.
