Butler and Stringham left immediately after the battle, the former to Washington and the latter accompanying the prisoners to New York. Critics argued that each was trying to gather credit for the victory to himself. The pair contended, however, that they were trying to persuade the administration to abandon the original plan to block up Hatteras Inlet. In Federal hands it was no longer useful to the Confederacy, and in fact now allowed Union forces to pursue raiders into the sounds. Although they and their supporters continued to press the case for several weeks, it seems to have been unnecessary. The War and Navy Departments had already decided to retain possession of the inlet, which would be used as the entry point of an amphibious expedition against the North Carolina mainland early the next year. This campaign, known as Burnside's North Carolina Expedition for its senior Army commander Ambrose E. Burnside, completely removed the sounds as sources of commerce-raiding activity.
