Michigan City, Indiana.
Michigan City, in the confederation of Indiana, is one of the largest cities in the Confederation of North America. It is a rail hub, a site of major steel production, and a financial capital surpassed only by New York City and rivaled only by Norfolk. Major newspapers in the city include the Michigan City Dispatch, the Michigan City Ledger and the Michigan City Star.
The focus of the dramatic growth of Indiana, Michigan City grew by 1840 into an urban center of half a million people, the fifth largest in the C.N.A., on what had been uninhabited swampland thirty years before. Like other Indiana cities it was heavily fortified against native attack, but that did not prevent its capture in 1839 by the messianic warrior Chief John Miller, who massacred 5000 civilians after a two-week battle. Retribution was swift, however, at the hands of General Winfield Scott (a former resident of the city) and his combined C.N.A. army, who overwhelmed Miller's forces and took no prisoners.
With rail connections to the N.C. by 1836 and the growth of steel production, Michigan City became the dominant center of the western C.N.A., surpassing St. Louis with its river connections and ties to the Southern Confederation. By 1878 it has two of the C.N.A.'s twenty largest banks. It remained a center for immigration -- ethnic gangs were a noticeable problem in 1868 and by 1930 half the population were recent arrivals (mostly Negro) from Southern Vandalia. In 1937 protests against the impending Global War led to a total breakdown of social order for three days.
In 1969 a Mexican espionage operation in Michigan City was found by the C.B.I., aimed at obtaining the secrets of the atomic bomb.
It seems clear that Sobel intended Michigan City to be on the site of Chicago IOW.
