that Sunday so that the deal might not be vetted by President Theodore Roosevelt himself before the stock exchange opened the next day. Convinced by Gary that U. S. Steel only wished to purchase Moore and Schley's stock in order to inject liquidity into the firm and thereby shore up investor confidence in the wider economy, Roosevelt granted the transaction antitrust immunity in November 1907, a decision for which he was later derided by critics as a hypocrite. Indeed, in 1911 the federal government sought to undo what it perceived to be Roosevelt's mistake and (without success) sued U. S. Steel. In the meantime, Moore and Schley was saved from collapse, the panic soon subsided and U. S. Steel was rewarded with a valuable prize – a controlling stake in TCI. U. S. Steel immediately replaced the Tennessee Coal, Iron and Railroad Company on the Dow Jones Index, where it remained until 1991. U. S. Steel TCI was not fully incorporated into U. S. Steel, and continued to operate as an extremely profitable subsidiary of its parent company well into the 20th century. Immediately following the merger, a venture was launched to create a new, larger TCI plant to the west of Ensley and at the center of a new company town, and so in 1910 work on the planned community of Corey, Alabama, began. Named after an executive who later committed suicide, Corey was soon renamed Fairfield, and the steel works there opened in 1917. With the discovery of new coking coal and ore deposits in the region, and with the aid of U. S. Steel's enormous capital, the Fairfield works were quickly expanded with the construction of new steel mills and rail links. Several rolling mills were completed in 1917, which produced ship materials for the nearby shipbuilding plants in Chickasaw, Alabama, in support of America's sudden entry into World War I. In 1920 a direct rail line between Fairfield and Birmingport, the new port of Birmingham on the Warrior River was opened. This was followed by the completion of the 'High Ore Line Railroad', which connected the Red Mountain and the Fairfield works; trains literally rolled down the hill from mine to mill. In 1923 a merchant steel mill was completed, followed by the opening of a sheet products mill in 1926. TCI proved to be so efficient at making cheap steel that a post-merger internal tariff
