It was the policy of the Confederacy to send out vessels to prey upon the commerce of the United States. Some of them began their depredations without making a port in the South, and a few of the swift steamers that succeeded in getting into Mobile, Wilmington, and other safe places, were fitted out for the work of destruction. The fog that prevailed inshore was favorable to blockade-runners; and if there was a vessel of this character in Cape Fear River, the early morning had been such as to tempt her to try to make her way through the blockaders to sea.
