Ralph Terry enlisted in Company C of the 24th Michigan Infantry Regiment in 1862. The regiment was soon assigned to the most famous unit in the Union Army - the Iron Brigade. The 24th Michigan needed to prove itself, and did so at Fredericksburg, earning them the coveted "black hats", but would later pay for them in blood at Gettysburg, and numerous other battles. Thank God for Michigan is the story of Ralph Terry's experiences.
