The expedition was first organized under Commodore Thomas Ap Catesby Jones, United State Navy, but finally the President of the United States appointed Lieutenant Charles Wilkes to command the squadron, and he was formally assigned to this duty under instructions of Secretary Paulding, dated August 11, 1838.
Charles Wilkes was born in New York City, April 3, 1798, and entering the United States Navy as a midshipman at the age of nineteen was promoted to be lieutenant in 1826. He had long served in the department of charts and instruments and was especially qualified for the proposed astronomical and surveying work connected with the expedition.
An anomalous feature of the expedition was the acceptance of appointment as second in command by Lieutenant William L. Hudson, whose naval rank was above that of Wilkes’s. The squadron, then consisting of the sloops of war Vincennes and Peacock, the store-ship Relief, the brig Porpoise, and tenders Sea Gull and Flying Fish, left Norfolk, Va., August 13, 1838. Associated with Wilkes were a number of lieutenants destined to later distinguish themselves in their country’s service, among whom may be mentioned T. P. Craven, James Alden, S. P. Lee, G. F. Emmons, and A. L. Case, all of whom afterward rose to be rear admirals, and H. J. Harstene, later associated with the relief of Kane. Under its instructions the expedition was to visit Rio de Janeiro, Cape Frio, the Rio Negro, Terra del Fuego, the Antarctic Ocean southward of Powell’s group to Cook’s farthest, Valparaiso, the Navigators’ Group, the Feejee Islands, the Antarctic regions south of Van Dieman’s Land, whence it would return home by way of the Sandwich Islands, San Francisco, Singapore, and the Cape of Good Hope. No ship had steam-power, nor was any vessel of the squadron fitted with appliances for protection in ice navigation; indeed, the squadron was a makeshift, ill-suited for so long and dangerous a voyage. Eventually the Sea Gull was lost in a gale off the coast of Chili, the Flying Fish proved of little use, and the extreme slowness of the Relief delayed the voyage.
Wilkes sailed for the Antarctic regions from Orange Bay, near Cape Horn, on February 24, 1839, but owing to the lateness of the summer accomplished little, and spent thirty-six days in attempting to visit Palmer’s Land, which was only sighted.
A second attempt at Antarctic exploration was made by Wilkes from Sidney, N. S. W., which was left December 21, 1839. A compact barrier of field ice, with frequent large bergs, was fallen in with on January 11, 1840, and from this time on the ships were often in imminent danger owing to continuous ice, impenetrable fog, bad weather, and occasional embayment of the vessels in the ice-pack. It is scarcely needful to enter into the details of Wilkes’s perilous voyage from longitude 95° E. to 155° E. and in latitudes ranging from the Antarctic Circle to the neighborhood of the seventieth parallel. It may be mentioned, however, that the Peacock narrowly escaped entire destruction by collision with a heavy iceberg, which seriously injured the ship. Fortunately she cleared the berg in time to escape crushing by the falling of detached ice masses from the overhanging floe berg. Heavy gales and the bad sanitary condition of the ship caused the medical officers of the Vincennes to specially report to Wilkes that such continued exposure would so weaken the crew by sickness as to hazard the ship and the lives of all on board. Wilkes, however, had sighted the long-looked-for Antarctic land, and, disregarding the warning, followed the coast-line eastward, keeping his squadron as near it as the conditions would permit. The land was a series of lofty mountain ranges, often snow-capped, frequently broken by indentations, and, worst of all, shut out from immediate approach by an almost continuous ice-barrier, which in its extent, height, and appearance struck every beholder with admiration not unmixed with apprehension. This barrier rose perpendicularly from the deep sea to a height varying from one hundred to two hundred feet above the level of the water, which gave no bottom in soundings ranging from one hundred and fifty to two hundred and fifty fathoms. Despite this great depth of water, the perpendicular icy barrier was evidently grounded, thus indicating ice of a thickness of about one thousand feet.

Regarding the land discovered the first reliable observations were those of January 16th, when land was seen by Lieutenant Ringgold, of the Porpoise, and by Midshipmen Eld and Reynolds, of the Peacock, their statement running as follows: “The mountains could be distinctly seen stretching over the ice to the southwest.” On the 19th land was again visible from the Vincennes, Alden reporting it twice to Wilkes, and on the same day high land was seen by all the crew of the Peacock. The ships were then in longitude 154° E., 66° 20´ S., practically on the Antarctic Circle. On February 2d high bold land bordered by the ice-barrier was visible to the Vincennes and Porpoise in longitude 137° E., latitude 66° 12´ S. Five days later the westerly trend of the land as previously seen was confirmed by a well-defined outline of high land rising above the perpendicular ice-barrier, the Vincennes being in longitude 132° E., latitude 66° 8´ S. On February 9th, in longitude 123° E., latitude 65° 27´ S., the land is spoken of as being indistinct. At 8 A.M. of the 12th land was reported again, in longitude 112° E., latitude 64° 57´ S., the land being in about 65° 20´ S. and trending nearly east and west.
Wilkes says of the land and of his efforts to reach it: “The solid barrier prevented our further progress. Land was now distinctly seen from eighteen to twenty miles distant, bearing from S.S.E. to S.W., a lofty mountain range covered with snow, though showing many ridges and indentations.” Two days later he writes: “The 14th was remarkably clear and the land very distinct. By measurement we made the extent of coast of the Antarctic continent then in sight seventy-five miles and by approximate measurement three thousand feet high.”
In longitude 97° E., Wilkes found the ice trending to the northward, well out of the Antarctic Circle, and after following it near to where Cook was stopped in February, 1773, Wilkes took his course for Sydney, where he learned that an English sealer, Captain Balleny, had discovered land in longitude 165° E., south of and near the point where Wilkes found the ice-barrier, and had attained a latitude of 69° S. in longitude 172° E. Here Wilkes, hearing of the prospective arrival of Sir James Clark Ross, forwarded for his benefit a tracing of the chart prepared as the American squadron had passed along the barrier, supplemented by the discoveries of Balleny. Ross publishes a copy of this chart in his “Voyage to the Southern Seas,” together with Wilkes’s letter, giving information not only as to discoveries, but also as to winds, currents, and the probable position of the magnetic pole.
