Captain Farragut is determined to secure the city of New Orleans for the Union. The Richmond government considered the city unconquerable and stripped it of its defensive resources. Audacity was the order of the day and New Orleans would fall. Sailing ships and steam powered vessels, wooden hulls and ironclads, gunboats and forty-eight gun frigates sailed against Fort Jackson and Fort St. Philip for mastery of the mouth of the mighty Mississippi River. The Union fleet would sail farther north to assist in the battles being fought in Tennessee, at Corinth and Memphis, and succeed in restricting the Confederate fleet to the river between Memphis and Baton Rouge. The cities of Vicksburg, Charleston, and Pulaski would all see naval action significant to the outcome of the war.
