William Burr Wooster was born on August 22, 1821 in Oxford, Connecticut, the son of Russell and Avis Burr Wooster. He attended the South Britain Academy and in 1846 graduated from Yale Law School. In 1858 he was elected to the state House of Representatives from the town of Derby, and in 1859 he was elected to the state senate. In 1861 he returned to the state house of representatives.
“In politics he has been a republican from the outset, and the honesty and uprightness of his political views have been exemplified in every step of his career. He believed in abolition, and led his troops with the idea uppermost in mind that the war would result in the abolition of slavery. But it required great moral courage not less than loyalty to one’s convictions, to assume the leadership of a regiment of colored men even in 1864. All honor is due to Colonel Wooster for the frankness and manliness of his course.”
