Lieutenant Charles Wilkes discovers Antarctic Coast
On January 19th, 1840, Lt. Charles Wilkes, during an expedition circumnavigating the globe, became the first American to sight the Antarctic Coast, and to discover the existence of an Antarctic continent. This discovery was the highlight of a four-year surveying expedition which greatly contributed to the scientific and cultural knowledge of the time. In October 1939, Proceedings published a detailed article about the expedition, excerpted below, written by Captain G. S. Bryan, U. S. Navy. In his article, Captain Bryan charts the course of Wilkes’ expedition, from beginning to end, and emphasizes not only the profound impact of the expedition and its discoveries, but the character and temperament of the commander responsible for its accomplishments as well:
The closing months of 1939 and early 1940 mark the one hundredth anniversary of the crowning achievement of the United States Exploring Expedition, or the Wilkes Exploring Expedition as it was later called. The accomplishments of this expedition under the command of Lieutenant Charles Wilkes, U. S. Navy, stand perhaps as the greatest achievement in the field of exploration that this country has ever known.
In its almost ceaseless wandering for nearly 4 years, this expedition circumnavigated the globe, investigating numerous dangers reported to exist, surveying still more numerous lands, discovering many new lands, and proving the nonexistence of others. Voluminous data were collected at each place visited which added greatly to the scientific knowledge of the day; and the various surveys, weather observations, and other hydrographic data collected greatly increased the store of maritime knowledge then existent.
The most notable accomplishment was the discovery of the existence of an Antarctic Continent. Although one or two short stretches of this continent had been sighted shortly before, it remained for the Wilkes Expedition to develop its extent by skirting the coast for over 1,500 miles, sighting land with sufficient regularity to demonstrate beyond doubt that this was a continuous coast line, and not that of a number of isolated islands.
Five large volumes, afterwards written by Wilkes, which comprise the narrative of this expedition, constitute a modern odyssey which entitles the expedition and its leader to a niche in the Hall of Fame along with Columbus, Cook, Magellan, and other better-known explorers. Unfortunately, however, neither the expedition nor its intrepid leader has ever received the prominence and publicity to which they are entitled. Perhaps the centennial of his voyage may have served to awaken interest in this subject and to correct injustice and neglect.
The whaling industry, then in its heyday, appears to have supplied the principal motive for this expedition, although the Act of Congress authorized it for “the safeguarding of American whale-fisheries, the promotion of commerce, and the safety of future navigation with the extension of scientific knowledge in general.” For some reason the proposal to authorize the expedition provoked a bitter debate in Congress. Two years of bickering occurred before the bill was passed in May, 1836.
The wrangling in Congress was only a forerunner, however, of what was still to come. Political interference and faulty organization and administration not only delayed, but cast doubt and ridicule on the expedition. At least three officers were successively placed in command and afterwards resigned. Almost two years passed and still little progress had been made on the project. At this time, March, 1838, the Secretary of the Navy placed Lieutenant Charles Wilkes in charge of the expedition and instructed him to organize it anew.
Born in New York, April 3, 1798, Lieutenant Wilkes had entered the merchant service when 17 years of age, and was appointed a midshipman in the Navy two years later. His record, prior to the expedition, included cruises in the Pacific Ocean and the Mediterranean in addition to some notable surveying duty. In 1833, he was appointed as Head of the Depot of Charts and Instruments, the forerunner of the present Hydrographic Office and Naval Observatory. By this time he had acquired a reputation as a navigator and scientist which well qualified him for the work in question. He has the distinction of being the first in the United States to set up fixed astronomical instruments and observe with them.
As regards his personal characteristics, he was a man of indomitable fearlessness and courage but possessed of a fiery temper and rash impetuosity which often got him into trouble. He has been referred to as the stormy petrel of the Navy. These traits of character were very much in evidence in the Trent Affair, years later during the Civil War, when Wilkes, then in command of the San Jacinto, seized the Confederate Commissioners, Mason and Slidell, from a British ship, almost causing a war with that country.
In keeping with his reputation as a man of action, Wilkes immediately plunged into the work of reorganization which had baffled his predecessors. Political interference still continued, and objections were made to having an officer of such junior rank in command, but this failed to deter him in the work of organizing and equipping the expedition. The reduction in the number of vessels, which it was decided at this time to send on the cruise, was an added handicap.
No expense had been spared in purchasing the best instruments obtainable. Wilkes himself had selected most of them while in Europe before he was ordered in command. One item consisted of 29 chronometers.
These vessels made up the expedition:
Vincennes, Flagship . . . sloop of war. . . . 780 tons
Peacock . . . . . . . . . . . . . sloop of war . . . .650 tons
Porpoise . . . . . . . . . . . . .brig . . . . . . . . . . .230 tons
Relief. . . . . . . . . . . . . . . store ship
Later two tenders, the Sea Gull and the Flying-Fish, were added. These were former New York pilot boats of 110 and 96 tons, respectively.
In addition to the regular naval complement of officers and men, a staff of civilian scientists were carried on the Vincennes and Peacock. These included three naturalists, two botanists, a mineralogist, a philologist, a taxidermist, and two draftsmen. The collection of data on hydrography, geography, astronomy, terrestrial magnetism and meteorology was assigned to the naval personnel.
Wilkes was under no illusions as to the condition of the ships assigned him. They were ill-equipped for making a sustained cruise of this proportion and the crews were quite restive. A letter had been forwarded to the Secretary of the Navy in which they had set forth their discontent and objection to having a new and younger set of officers placed over them. After the multitudinous delays which had occurred, however, Wilkes decided that the best policy was to set sail as early as possible and accordingly early in July the squadron assembled at their rendezvous at Hampton Roads.
On July 26, 1838, President Van Buren, accompanied by Secretary of the Navy Paulding and Secretary of War Poinsett, reviewed the tiny squadron. This occasion apparently added considerably to the morale of the expedition. August 10 was set as the date of readiness although few thought it could be met. Wilkes was adamant, however, and in view of previous exasperating delays, he determined to report ready on that date regardless of whether or not the ships were completely equipped. The date was met.
The letter of instructions from the Secretary of the Navy dated August 11, 1838, is a rather interesting document. It outlined the general purpose and course of the expedition, listed the many countries and islands to be visited and the numerous reported shoals that were to be investigated and their exact location established or proved nonexistent. It directed that the Southern Ocean be explored and surveyed, that the existence of all doubtful islands be checked, and laid down a general code for dealing with natives of countries or islands visited. He wrote:
The expedition is not for conquest but discovery. Its objects are all peaceful. They are to extend the empire of Commerce and Science; to diminish the hazards of the Ocean and point out to future navigators a course by which they may avoid dangers and find safety.
Among the minor points of interest was the admonition “to teach the natives the modes of cultivation and to encourage them to raise hogs in greater abundance.” Also of interest was the strict injunction that no information was to be given out regarding the cruise prior to its publication officially.
With these orders as a guide, the expedition set sail from Hampton Roads the morning of August 18, 1838, on the long voyage of discovery which was to end nearly four years later after they had completely encircled the globe. Dangers there were in plenty and enough of adventure to satisfy the boldest. Many hardships were to be endured, and internal dissension added to their troubles during the long cruise. Whatever was lacking, however, their courage never failed them, and in spite of all handicaps, the expedition was successful in that they carried out their orders and accomplished what they had set out to do.
On arrival at any port, the routine of the expedition was generally the same. An astronomical station was set up, and as complete a survey as possible was accomplished; while the scientists went ashore and investigated the country’s geology, botany, etc. A general description of the place was made with particular reference to the history, type of government, manners and customs of the natives, and the general subject of commerce. Castaways and shipwrecked sailors were often encountered and received on board. At times they were called on to handle cases where members of whaling ships or other vessels had been murdered by natives. If the native chiefs failed to take proper action, Wilkes usually took the matter into his own hands and meted out punishment.
On departure from Hampton Roads, the tiny squadron headed first for Madeira, passing within sight of the Azores en route. They arrived at Madeira on September 16 and spent about 10 days there collecting data. From this island they journeyed south to the Cape Verde Islands, passing near the Canaries and investigating various shoals and dangers reported to exist in these waters. None of these were found as reported, and the squadron anchored in Porto Praya Bay, Cape Verde Islands, on October 6.
Only one day’s stop was made here before the departure of the expedition for Rio de Janeiro. Several shoals and islands, which had been reported, were investigated during this part of the cruise, but none of them could be located. Wilkes continued on and arrived off Rio on November 23, 1838. About a month and a half was spent in this region.
Shortly after New Year’s Day, anchors were again hove up and sail set to the southward. The squadron anchored off the Rio Negro anchorage for a day or so and then continued to the southward passing through the Straits of LeMaire on February 13, 1839, rounding Cape Horn and continuing on to Orange Harbor on the southern coast of Tierra del Fuego. This place had been selected as a rendezvous preparatory to their first antarctic voyage. Just prior to arrival at this port, they experienced the first of the many remarkable mirages which they were to encounter.
After a short stop at Good Success Bay, they anchored in Orange Harbor on January 30, 1839. In addition to their routine investigations, preparations were made for the first journey into the Antarctic. Wilkes now shifted to the Porpoise, leaving the Vincennes for the time being to continue with the surveys of the various waters of Tierra del Fuego.
The instructions were to explore to the southward of “Powell’s Group” and to endeavor to reach a high southern latitude. The Porpoise, with the tenders, left Orange Harbor on February 25, and on March 1 their first iceberg was sighted. Continuing, they sighted several islands of the South Shetland group and eventually Palmer’s Land hove in sight. The weather meanwhile had been most inhospitable. Gales, fog, and the ever increasing number of icebergs rendered the continuation of the cruise precarious. Finally, despairing of finding an opening through which they could penetrate farther south, and considering the lateness of the season and the physical condition of the crew, it was decided to return to the base at Orange Harbor. With intermittent fog enveloping them on the return northward, they had several narrow escapes from collision with icebergs, and once almost grounded on Elephant Island.
Orange Harbor was reached on March 30 and was a welcome sight. Meanwhile, the Peacock and Flying-Fish had sailed farther to the westward seeking the ne plus ultra of Cook. Stormy weather and bitter cold made life miserable for the crews of these two ships. The ice barrier was followed for some distance and a latitude of 70° S. was reached but the lateness of the season, a few narrow escapes from collision with icebergs, and the suffering of the crew, united to cause their leader to decide to head north. Apparently Wilkes’ inexperience in polar conditions had caused him to time this part of the expedition too late in the season.
The Relief sailed through the Straits of Magellan but the remaining ships of the squadron left their base on April 17, 1839, and with the exception of the Sea Gull arrived at Valparaiso on May 15. That vessel was last sighted on April 29 off Cape Horn and was never heard of again. Two officers and a crew of 15 were lost, probably due to the vessel’s foundering in a storm which occurred at that place and time.
. . .
In the Tuamotu group about 6 weeks were spent, which also included a visit to Tahiti of the Society Islands. On September 27, 1839, both island groups were left behind as the squadron sailed for the Samoan Islands. Slightly over a month was spent here, all the principal islands being visited and surveyed. On November 10, 1839, the expedition headed for Port Jackson and Sydney, New Holland, or to give it its modern name, Australia, where work of fitting out for the second antarctic cruise was to be carried out. A few small islands were investigated en route.
Only about a month was utilized for the necessary preparations for the venture south into the vast unknown antarctic regions. Had they anticipated the hardships and dangers they were to encounter, it is probable that a much longer time would have been taken. These ships were never designed for cruising in the polar regions and were ill-fitted for service there. This fact, however, was not sufficient to deter Wilkes.
Two other nations, the British and French, had also planned to explore the antarctic at about this time. The French Expedition under D’Urville was in this locality at the same time as Wilkes. The British Expedition under Ross followed a year later. The south polar region was a blank on the charts of that time, although intrepid whaling ships regularly braved these cold and stormy areas in pursuit of their calling. No one knew what lay to the southward or whether there was any opening in the great ice barrier through which ships might penetrate beyond. It was for the purpose of finding the answer to this question that the three expeditions were organized.
Wilkes with his poorly equipped squadron left Port Jackson (Sydney) shortly after Christmas in 1839 after having designated Macquarie Island as a rendezvous. This island was reached about two weeks later but only served as a point for assembling his ships as they immediately pressed on to the southward. Increasing cold was now encountered, icebergs began to loom around them, and sleet and snow accompanied the storms they met as they drove steadily on. The barrier of ice next hove in sight forcing them to turn to the westward, and on January 16, 1840, in the far distance beyond the barrier, was sighted what all three ships were convinced was land looming up over the horizon. This had the appearance of an island and was so described at the time.
Following the barrier as closely as possible, Wilkes now continued to the westward hoping to find an opening through which he could proceed farther south. On January 19 land was again sighted from the Vincennes and later in the day from the Peacock—mountains looming up over the ice barrier to the southwest. This landfall was designated Cape Hudson by Wilkes. Although it was sighted from both ships, and sketches of it were published by Wilkes, this land, or at least its location, was afterwards to be the subject of a dispute which continues to this day.
Still seeking an outlet to the southward, the little ships continued beating to the westward along the ice barrier. On January 22, while investigating a small bay in the barrier ice, the Peacock was caught among the icebergs with the result that her rudder was crushed and considerable other damage done, as she collided with an immense ice floe. Only unusually fine seamanship and skillful handling saved the ship from entire destruction. When she was finally extricated, it was found that the damage was so great that it was considered dangerous for the ship to continue her work of exploration. Accordingly, the ship headed north, abandoning any further part in the expedition until repairs could be made.
The following day, the appearance of land was again observed by the Vincennes but it was still impossible to make any headway towards it on account of the barrier ice. The ships still continued to skirt the barrier to the westward, however, and on January 28 were rewarded with a sight of land directly ahead. They approached to within half a mile of it, but the gale blowing at the time prevented lowering a boat for landing.
As the land in sight extended for a considerable distance, both to the eastward and to the westward, and considering his previous landfalls, Wilkes now for the first time concluded that he was in contact with a land of continental dimensions. ”I gave the land the name of the Antarctic Continent,” he wrote at this time. As the section of the coast explored by him, ranging from about 95° to 153°E. Long. constituted only a relatively small part of the Antarctic Continent itself, it has been the practice of most geographers to refer to this section as Wilkes Land. It has been suggested that the smaller sections of land, which have been explored more in detail in this area, should be known as “coasts,” instead of “lands,” reserving the latter designation for major divisions of the continent.
The conclusion that this was a continent with which he was in contact, did not, however, complete Wilkes’ exploration in the antarctic. The blank space on the chart to the westward was still to be investigated and the ships again pushed on to develop the coast line in that direction. Stormy weather and bitter cold continued to take its toll among the crew, and the physical condition of the men was such that the medical officers wrote a letter of protest against continuing the cruise. A board of officers ordered by Wilkes to investigate this charge concurred in the recommendation of the medical officers. A less indomitable commander would probably have decided to abandon further exploration in this climate, but Wilkes was adamant and ordered the squadron to continue the cruise.
Again land was sighted on February 2, 1840, but thick weather set in and a gale, which lasted until the 7th, shut out the view and prevented any further approach towards the shore. On the latter date, the high mountains beyond the barrier were again visible and as the ships continued to the westward, still another landfall was made on February 10. Two days later land was distinctly made out which remained in sight throughout the day. For the next few days sighting of land was a daily occurrence but all attempts to find an opening through the barrier by means of which a landing or even a closer approach could be made were frustrated.
On February 17, although what appeared to be land was sighted, the direction of the trend of the barrier ice was shifted to the northward and eastward and from now on as the expedition wended its way skirting this barrier as closely as possible, no more land was sighted. On February 21, 1840, having reached the latitude of 61°-30′ S., Wilkes decided that his mission had been completed and, calling all hands aft, he announced to their great joy that they were now to head north and continue their explorations in more hospitable and temperate areas.
About three weeks later the squadron was again in Sydney for a badly needed overhaul preparatory to resuming their explorations anew. This overhaul was completed in about 3 weeks, and on March 19 the expedition again set sail and stood towards New Zealand, anchoring in the Bay of Islands on the 30th. A week later they were again under way heading for Tongataboo Island, one of the Tonga group. During a 2-week stay at this island, Wilkes undertook to mediate in a tribal quarrel between two factions of natives with rather negative results. The Fiji Group was next visited on May 5, and, as this group was considered of considerable importance, about 3 months were utilized in collecting data and surveying the islands.
. . .
All hands now turned to surveying, and for the next 6 months the various parts of the Straits of Juan de Fuca and Puget Sound were surveyed and mapped. All the data they could acquire were obtained from the settlers and missionaries in that region and from various posts of the Hudson Bay Company. Three extensive exploring expeditions were made inland. One under Wilkes landed at Nisqually (near present site of Tacoma), struck downward to Fort Vancouver just north of present site of Portland, followed the Columbia River and the Willamette Valley to the Falls. A second expedition from Nisqually crossed the Cascade Range north of Mt. Rainier, continued onward to the Columbia, crossing it and later penetrating to Fort Colville almost at the northeastern corner of Washington State. Returning they penetrated into Idaho reaching Lake Coeur d’Alene, turned south following the Snake River to Fort Walla Walla, thence journeying back to Nisqually. This expedition devoted some study to the Grand Coulee which it passed en route. A third expedition followed the Columbia River up to its junction with the Walla Walla River.
. . .
Wilkes had originally planned to stop at Japan, but the delay incident to the stranding of the Peacock caused him to change his plans and omit that country from his itinerary. His orders were to arrive in New York by May 31, 1842, and this left him little time. On leaving Honolulu, the squadron again split up. The Porpoise and Oregon explored the small islands and reefs of the Hawaiian group to the westward, then rounded northern Luzon and proceeded direct to Singapore.
Wilkes with the Vincennes and FlyingFish headed southeastward, investigating various islands reported to exist in those waters but was unable to find any trace of them until he arrived at Wake Island which was reached on December 20, 1841. Boats were sent to make a quick survey which was completed that same day. Continuing they sighted Grigan, the northernmost inhabited island of the Ladrone group, and discovered Assumption Island although they did not stop there. From that island they rounded the northern end of Luzon and anchored in Manila Bay on January 12, 1842. The Flying-Fish separated en route passing through the southern part of the Radack group. Skirting to the northward of the Carolines she passed through San Bernardino Channel and arrived at Manila the same day as the Vincennes.
The short time remaining was now an important factor and prevented any considerable period being spent at anyone place. The two ships therefore left Manila after a stay of only 9 days and proceeded south into the Sulu Sea making a few stops en route, various surveying jobs being meanwhile assigned to the tender. The charts of this region were found worthless and the pilots were little better. On February 2, the ships anchored off the Island of Sulu and Wilkes immediately entered into negotiations for a treaty with the Sultan governing commerce between Sulu and the United States. This was drawn up and signed and shortly thereafter Wilkes got under way for Singapore.
. . .
The closing “leg” of the cruise was uneventful. On June 10, 1842, the expedition dropped anchor off Staten Island thus writing the closing chapter of one of the greatest epics of the sea. All hands were now called aft and Wilkes expressed his thanks to them all for the manner in which they had conducted themselves. A national salute was fired, and Wilkes’ pennant was hauled down as he left the ship for the last time.
During the course of the expedition, hydrographic surveys were made of some 280 islands as well as of the inland waters of what is now United States territory extending from the Straits of Juan de Fuca to San Francisco Bay. The existence of the Antarctic Continent had been added to the world’s knowledge of geography and 1,600 miles of its coast had been followed to substantiate the claim.
Charts to the number of 180 were constructed by Wilkes as a result of the expedition. In addition to the narrative of the expedition which consisted of 5 large volumes, some 14 volumes were published covering the researches in geology, botany, ethnology, meteorology, hydrography, etc., and 5 volumes for some reason were not published although they were listed in the series. A number of atlases were published and the proved nonexistence of many islands affected other charts to a large extent. Many botanical species were brought back and about 2,000 sketches made during the exploration.
In spite of the fact that the results obtained by the expedition branded it as an outstanding achievement for the country’s first venture in this field, the reception accorded Wilkes on his return was far from that usually given returning heroes in this country. The reason for this was soon apparent. Always a martinet, he had on numerous occasions incurred the animosity of some of his officers, and while this enmity only smoldered during the progress of the cruise, it now broke into the open.
Wilkes was assailed on the floor of Congress and charges were preferred against him by some of his officers which resulted in his being brought to trial before a general court-martial. These charges ranged from disrespect to his superior officer and cruel and inhuman treatment of his men, to murder, the latter charge based on the incident where the slaughter by cannibals of two of his officers on Malolo Island was avenged by an armed landing party. He was acquitted by the court on all the charges.
During the progress of the trial, however, one officer carried his animosity toward Wilkes to the extent of testifying that he had falsely reported sighting land in the antarctic on January 19, 1840. Although this testimony was refuted by the testimony of two officers and several of the crew, nevertheless an officer of the expedition had been found who had cast doubt on the authenticity of Wilkes’ discoveries, and this incident was to be used later in attempts to discredit him.
This incident was not the only one to be used against him, however. For some reason or other—possibly professional jealousy or overzealous patriotism—Wilkes was shortly afterwards subjected to considerable criticism by some of his contemporaries. How unjust and unfair this criticism was is readily seen when the facts are examined.
On a tracing of his preliminary chart which Wilkes sent to Ross as a generous courtesy to this rival, there was shown a patch of land in the general vicinity of the Balleny Islands but somewhat to the eastward. This was intended to represent the general area of this land as taken from Balleny’s own report. Not only was this not a part of the Antarctic Continent but actually Wilkes never mentioned sighting it. On the chart shortly afterwards published by Wilkes, this land was not shown at all. Ross had a copy of the published chart in his possession in 1841 when he sailed through this spot and found no land. Nevertheless, this did not deter him from asserting that he had sailed through Wilkes Land and thereby proved that it did not exist.
Actually Ross explored a different section of the Antarctic Continent, and never passed near any of the land reported by Wilkes. However, this statement and others regarding the Antarctic Continent were taken up by some geographers and enlarged upon until it became almost a tradition that Wilkes had been thus discredited and his other reported landfalls, not having been confirmed by any other explorer, probably also did not exist. As no other expedition subsequently explored this section of the continent for almost 75 years, this assumed doubt gradually became a conviction.
Early in the present century some of Wilkes’ landfalls shown on the eastern part of his chart (around Cape Hudson) were shown to be some distance to the northward of any known land, and the same is true of Cape Carr and Termination Land. However, these discrepancies may be satisfactorily explained.
On the chart prepared by Wilkes of this region, he laid out the tracks of his vessels, the general contour of the ice barrier, and the approximate positions where he had sighted land at different times. At no time was he able to actually set foot on land and most of the high land was sighted by him from a distance. These distances could not be accurately measured, and so it naturally follows that the positions shown for these lands are only rough estimates at best. Further, it is well known by students of polar exploration that the weather in the antarctic is very conducive to mirages and that due to this condition, on clear days land may sometimes be sighted looming over the horizon’ at extreme distances even up to as much as 150 miles. As mountainous land exists in the general direction as seen by Wilkes but much farther away than shown, it is possible that unusual visibility in connection with a mirage might have accounted for the large errors in distance. This theory is very plausibly expounded by Professor W. H. Hobbs (“Wilkes Land Rediscovered,” Professor W. H. Hobbs, in Geographical Review, October, 1932), who cites several examples where even the most severe of Wilkes’ critics were themselves proved to be the victims of large errors in estimating positions of land seen in the antarctic distance. This author cites the log of the Aurora (Shackelton’s Expedition in 1915) which mentions sighting “Cape Hudson” clearly from near where Wilkes saw it, though in clear weather the following day it could not be seen.
It is, of course, possible that some of the land reported by Wilkes may have been only a mistaken view of a ridge of the barrier ice, as claimed by some of his critics. When landfall after landfall was reported, however, as he sailed farther to the westward and this land was visible clearly enough to be sketched, there seems to have been no logical reason for assuming that all his reports of land were erroneous and therefore the Antarctic Continent did not exist.
However, for about three-quarters of a century, many geographers did choose to ignore “Wilkes Land” and it remained for the two expeditions of Mawson in 1911-14 and 1930-31 to prove that, with the questionable exceptions of the eastern and western limits, land did exist for the greater part of the continental coast line explored by Wilkes and in the approximate positions assigned it by him. It should also be mentioned that the positions of land reported by Mawson are also only approximate except as to those points where he actually landed, and they may be subject to error to the same extent as those of any explorer sighting land at a great distance. Strangely enough, however, although Mawson’s expeditions were the means of confirming the discoveries of Wilkes regarding Norths High Land, Tottens High Land, Budds High Land, and Knox High Land, that explorer claims the credit for his own expedition as being the first to sight them, although he admits that Wilkes believed he had discovered them.
No claim was ever advanced by Wilkes that he was the first to sight the Antarctic Continent. This had been done previously at one point or another by others, but none of these were aware at the time or claimed that the single stretch of land sighted by them was part of a huge continent that could only be established by developing the presence of a continuous coast line of considerable extent. This was actually accomplished, however, by Wilkes, and on this basis he did claim that a huge antarctic continent existed there and gave the approximate location of the coast line for about 1,500 miles. Now that this claim of Wilkes has been verified, surely there is no longer justification for denying him the credit for discovering the existence of the Antarctic Continent. On the other hand, belated justice demands that the name of “Wilkes Land” be restored to the entire stretch of the coast discovered by Wilkes and that lesser subdivisions be designated as “coasts”; as for instance, “Adelie Coast” instead of “Adelie Land.”
Following his return and subsequent court-martial, Wilkes was ordered to duty with the Coast Survey and was promoted to the grade of commander in 1843. The following year he was assigned the duty of preparing for publication the material collected by the expedition. This duty continued until the outbreak of the Civil War. Meanwhile, having been promoted to the rank of captain, he was assigned to command the San Jacinto and during the war was prominent in the Trent Affair as mentioned previously. He was promoted to the grade of commodore in 1862 and retired for age in 1864. Two years later he was given the rank of rear admiral on the retired list. His death, which occurred about 10 years later, closed the career of a naval officer whose exploits constitute a glorious page in the history of this nation.
