By 1861, Springfield's population had grown to approximately 2,000, and it had become an important commercial hub. In the late 1850s, telegraph lines, previously only to St. Louis, reached Springfield. News from point further west was brought to Springfield overland and then sent by telegraph to what was then called the New York Associated Press. At the start of the American Civil War, Springfield was divided in its loyalty, as it had been settled by people from both the North and South, as well as by German immigrants in the mid-19th century who tended to support the Union.
