Control of the sea enabled the Union to transport and support troops; to move supplies rapidly by water; to launch large-scale amphibious assaults directed at Confederate ports and strongholds; to pursue warfare on the western rivers  that split the Confederacy along the vital Mississippi River line; and to maintain a  blockade of more than 3,000 miles of Confederate coastline from Virginia to Texas.

=====Blockade=====

As the [[Union Blockade|blockade]] gained in strength and effectiveness, it sealed off southern ports and made blockade-running of critical military and civilian supplies increasingly difficult and  hazardous; it denied the South easy access to supplies from Europe and the West Indies, while the markets of the world remained open to the North. The blockade also  discouraged direct foreign intervention in the war.

In combined operations with the Union  army--particularly at Hatteras Inlet (Aug. 29, 1861) and Port Royal, S.C. (Nov. 7, 1861),  and at Wilmington, N.C. (Jan. 13-15, 1865)--the Union navy seized strategic locations  on the Confederate coast. These actions not only deprived the South of  blockade-running havens but also provided the North with base facilities and coaling  stations, which enabled the blockading steamships to keep the sea for extended periods.
