In August 1861, Union commander Nathaniel Lyon finally caught up with Confederate troops under the command of General Sterling Price in Springfield, Missouri.
Lyon fell at the height of the action to become the first general officer of the Union army to die in battle. The site is now a national battlefield with a visitors center and The John K. and Ruth Hulston Research Library. At the visitors center films, maps and a museum will introduce you to the battlefield and explaing the battle's significance. There is also a self-guided tour brochure for exploring the site on your own. Be sure to visit the Ray House which served as a temporary field hospital.
