Arkansas occupied a key position in the Confederate Trans-Mississippi Department. It offered a gateway for Confederate troops to move north and secure Missouri for the Confederacy, or for Union troops to move south towards Texas and Louisiana. During the war, Union and Confederate armies moved back and forth across the state engaging in numerous encounters. This paper is a year by year study of those encounters and engagements occurring in Arkansas between 1861 and 1865. Emphasis is necessarily placed on the significant campaigns and engagements. Actions which occurred in adjacent states but which militarily affected Arkansas are also discussed. The majority of the material was compiled from the Official Records.

This study examines the efforts of the Union and Confederate diplomatic agents to influence the events along the Rio Grande during the Civil War. The paper compares the successful accomplishments of Confederate agent Jose Quintero to the hindered maneuverings of the Union representatives, Leonard Pierce and M. M. Kimuey. Utilizing microfilmed sources from State Department records and Confederate despatches, the paper relates the steps Quintero took to secure the Confederate-Mexico border trade, obtain favorable responses from the various ruling parties in northern Mexico, and hamper the Union agents' attempts to quell the border trade.
