This bill authorizes the Secretary of the Interior to permit the establishment of two distinct memorials honoring Wisconsin infantry officers and enlisted men who participated in significant Civil War battles. One memorial will be situated within Antietam National Battlefield, commemorating the Second, Third, Fifth, Sixth, and Seventh Wisconsin Infantry Regiments for their service at the Battle of Antietam. The second memorial will be located at Manassas National Battlefield Park, recognizing the Second, Sixth, and Seventh Wisconsin Infantry Regiments for their contributions to the Second Battle of Bull Run. The Secretary will select the entities responsible for establishing these memorials and must approve their size, design, and inscriptions. A key provision states that no Federal funds may be used for the design, acquisition, site preparation, or installation of these memorials. The Secretary can suspend authorization if fundraising efforts misrepresent affiliations, and annual reports on fundraising and progress are required until installation. Upon installation, the Secretary will assume responsibility for the memorials' maintenance and may accept contributions for this purpose.
