Based on this paragraph, what industry did Gardiner Hall create a business in and how was it impacted by the Civil War?

South Willington's industrial history began in 1840, when Origen Hall and two partners founded the Willington Thread Company. Hall and his brother Gardner founded a second company in 1848 for the production of cotton wadding and batting. After several failed business ventures, Gardiner Hall founded the Hall Thread Company in 1860, building what is now the oldest surviving industrial building in the village. This venture also failed due to a lack of cotton occasioned by the American Civil War, but Hall restarted the business in 1867. This business flourished, operating at the site until 1954. The Halls practiced a paternalistic form of management and care of the mill workers, building a school and church, as well as housing for their workers. The company's success was instrumental in the village's growth during the late 19th and early 20th centuries.[2]

Gardiner Hall was in the textile business and ran the Hall Thread Company. His business was impacted by the Civil War due to a cotton shortage, but he restarted the business following the Civil War.
