 Two raids on Indiana soil during the war caused a brief panic in Indianapolis and southern Indiana.The Newburgh Raid on July 18, 1862, occurred when Confederate officer Adam Johnson briefly captured Newburgh by convincing the Union troops garrisoning the town that he had cannon on the surrounding hills, when in fact they were merely camouflaged stovepipes.The raid convinced the federal government that it was necessary to supply Indiana with a permanent force of regular Union Army soldiers to counter future raids.
