Amos Pollard, chief surgeon of the Alamo garrison, son of Jonas and Martha (Martin) Pollard, was born at Ashburnham, Massachusetts, on October 29, 1803. He was raised in Surry, New Hampshire, and graduated from the medical school of the Vermont Academy in Castletown, Vermont, in 1825. Pollard lived for a time in Greenbush, New York, and then spent the years 1825 to 1834 practicing medicine at various locations in Manhattan. He married Fanny Parker in 1828, and they had one daughter. His wife died in 1831. In 1834 Pollard traveled to Texas by way of New Orleans.
He settled in Gonzales, Texas, and took part in the fight for the Gonzales 'come and take it' cannon, the opening skirmish of the Texas Revolution, on October 2, 1835. He later marched on San Antonio de Béxar as a private in Capt. John York's volunteer company. On October 23, 1835, he was appointed surgeon of the regiment by Stephen F. Austin.
After the siege of Bexar Pollard remained in the town as chief surgeon of the Texan garrison, on the staff of Lt. Col. James C. Neill. He cared for the sick and wounded of the garrison and also set up a hospital within the Alamo. On February 23, 1836, Antonio López de Santa Anna's Mexican army besieged the Alamo. Pollard died in the battle of the Alamo on March 6, 1836, probably defending the Alamo hospital. A portrait of him was done sometime before he moved to Texas. Besides Travis, Bowie, and Crockett, he is the only Alamo defender of whom a portrait was done from life. A copy of the portrait is on display in the Alamo.
