Understanding Battlefield Performance of U.S. Marines Ashore during the Civil War

During the American Civil War, U.S. Marines rarely engaged in land operations and even more rarely conducted land-based or amphibious operations involving more than one company. The Marine Corps’ lackluster battlefield performance ashore during the Civil War is best understood by examining their poor organization in officer selection, recruiting and retention, ad hoc formations larger than company size, limited collective tactical training, and experience in large-scale ground combat. The focus of this study is on large-scale Marine land operations, involving battalion-size elements assembled on an ad hoc basis and led by either U.S. Navy officers or U.S. Army officers, to analyze Marines’ battlefield performance ashore.
