THE GULF AND INLAND WATERS.

CHAPTER I.ToC

PRELIMINARY.

The naval operations described in the following pages extended, on the seaboard, over the Gulf of Mexico from Key West to the mouth of the Rio Grande; and inland over the course of the Mississippi, and its affluents, from Cairo, at the southern extremity of the State of Illinois, to the mouths of the river.

Key West is one of the low coral islands, or keys, which stretch out, in a southwesterly direction, into the Gulf from the southern extremity of the Florida peninsula. It has a good harbor, and was used during, as since, the war as a naval station. From Key West to the mouth of the Rio Grande, the river forming the boundary between Mexico and the State of Texas, the distance in a straight line is about eight hundred and forty miles. The line joining the two points departs but little from an east and west direction, the mouth of the river, in 25° 26' N., being eighty-three miles north of the island; but the shore line is over sixteen hundred miles, measuring from the southern extremity of Florida. Beginning at that point, the west side of the peninsula runs north-northwest till it reaches the 30th degree of latitude; turning then, the coast follows that parallel approximately till it reaches the delta of the Mississippi. That delta, situated about midway between the east and west ends of the line, projects southward into the Gulf of Mexico as far as parallel 29° N., terminating in a long, narrow arm, through which the river enters the Gulf by three principal branches, or passes. From the delta the shore sweeps gently round, inclining first a little to the north of west, until near the boundary between the States of Louisiana and Texas; then it curves to the southwest until a point is reached about one hundred miles north of the mouth of the Rio Grande, whence it turns abruptly south. Five States, Florida, Alabama, Mississippi, Louisiana, and Texas, in the order named, touch the waters bounded by this long, irregular line; but the shore of two of them, Alabama and Mississippi, taken together, extends over little more than one hundred miles. All five joined at an early date in the secession movement.

The character of the coast, from one end to the other, varies but slightly in appearance. It is everywhere low, and either sandy or marshy. An occasional bluff of moderate height is to be seen. A large proportion of the line is skirted by low sandy islands, sometimes joined by narrow necks to the mainland, forming inland sounds of considerable extent, access to which is generally impracticable for vessels of much draft of water. They, however, as well as numerous bays and the mouths of many small rivers, can be entered by light vessels acquainted with the ground; and during the war small steamers and schooners frequently escaped through them, carrying cargoes of cotton, then of great value. There is but little rise and fall of the tide in the Gulf, from one to two feet, but the height of the water is much affected by the direction of the wind.

The principal ports on or near the Gulf are New Orleans in Louisiana, Mobile in Alabama, and Galveston in Texas. Tallahassee and Apalachicola, in Florida, also carried on a brisk trade in cotton at the time of the secession. By far the best harbor is Pensacola Bay, in Florida, near the Alabama line. The town was not at that time a place of much commerce, on account of defective communication with the interior; but the depth of water, twenty-two feet, that could be carried over the bar, and the secure spacious anchorage within made it of great value as a naval station. It had been so used prior to the war, and, although falling at first into the hands of the Confederates, was shortly regained by the Union forces, to whom, from its nearness to Mobile and the passes of the Mississippi, as well as from its intrinsic advantages, it was of great importance throughout the contest.

The aim of the National Government in connection with this large expanse of water and its communications was two-fold. First, it was intended to enter the Mississippi River from the sea, and working up its stream in connection with the land forces, to take possession of the well-known positions that gave command of the navigation. Simultaneously with this movement from below, a similar movement downward, with the like object, was to be undertaken in the upper waters. If successful, as they proved to be, the result of these attacks would be to sever the States in rebellion on the east side of the river from those on the west, which, though not the most populous, contributed largely in men, and yet more abundantly in food, to the support of the Confederacy.

The second object of the Government was to enforce a strict blockade over the entire coast, from the Rio Grande to Florida. There were not in the Confederate harbors powerful fleets, or even single vessels of war, which it was necessary to lock up in their own waters. One or two quasi men-of-war escaped from them, to run short and, in the main, harmless careers; but the cruise that inflicted the greatest damage on the commerce of the Union was made by a vessel that never entered a Southern port. The blockade was not defensive, but offensive; its purpose was to close every inlet by which the products of the South could find their way to the markets of the world, and to shut out the material, not only of war, but essential to the peaceful life of a people, which the Southern States were ill-qualified by their previous pursuits to produce. Such a blockade could be made technically effectual by ships cruising or anchored outside; but there was a great gain in actual efficiency when the vessels could be placed within the harbors. The latter plan was therefore followed wherever possible and safe; and the larger fortified places were reduced and occupied as rapidly as possible consistent with the attainment of the prime object—the control of the Mississippi Valley.

Before the war the Atlantic and Gulf waters of the United States, with those of the West Indies, Mexico, and Central America, were the cruising ground of one division of vessels, known as the Home Squadron. At the beginning of hostilities this squadron was under the command of Flag-Officer G.J. Pendergrast, who rendered essential and active service during the exciting and confused events which immediately followed the bombardment of Fort Sumter. The command was too extensive to be administered by any one man, when it became from end to end the scene of active war, so it was soon divided into three parts. The West India Squadron, having in its charge United States interests in Mexico and Central America as well as in the islands, remained under the care of Flag-Officer Pendergrast. Flag-Officer Stringham assumed command of the Atlantic Squadron, extending as far south as Cape Florida; and the Gulf, from Cape Florida to the Rio Grande, was assigned to Flag-Officer William Mervine, who reached his station on the 8th of June, 1861. On the 4th of July the squadron consisted of twenty-one vessels, carrying two hundred and eighty-two guns, and manned by three thousand five hundred men.

Flag-Officer Mervine was relieved in the latter part of September. The blockade was maintained as well as the number and character of the vessels permitted, but no fighting of any consequence took place. A dashing cutting-out
