During the Civil War some of the earliest examples of joint operations in American Military history were undertaken. Except for General Scott's landing at Veracruz during the War with Mexico, joint undertakings in the form of amphibious operations were rare. Army and navy commanders had little experience dealing with the problems associated with the ideas of jointness. Doctrinal guidance was unavailable and commanders worked together often with mixed results. In eastern North Carolina, the Union attempted several joint operations during the course of the war. Attacks were crudely planned and executed by modern standards. The North appeared not to have drawn lessons from preceding campaigns in any systematic way. Nevertheless, a basic pattern did develop and was improved upon over time as seen by the progressive sophistication of the operations against Hatteras, New Bern, and Fort Fisher. Today, the United States military has certain fundamental principles of joint warfare that it employs. When they are applied to Civil War campaigns certain trends become evident. The success rate increased when careful planning and preparation were present and the modern principles of joint warfare were followed. Where these elements were missing, Union forces often met with defeat. Failure to anticipate and provide for contingencies doomed many Civil War campaigns and would do the same to modern-day joint operations. The principles of joint warfare are a tool; one designed to make the transition to fighting as a team easier. Using them does not guarantee the war-fighter success, but can greatly improves his chances.
