In fact, very little is known of the members that composed it; the only thing certain is that it was not at all adapted for the work that lay before it. A few words of the Reverend W.W.B. Clarke, the well-known geologist, have been many times quoted, and they convey about all that is known of the personnel of the expedition:--
"The parties that accompanied Leichhardt were perhaps little capable of shifting for themselves in case of any accident to their leader. The second in command, a brother-in-law of Leichhardt, came from Germany to join him before starting, and he told me, when I asked him what his qualifications for the journey were, that he had been at sea and had suffered shipwrecks, and was therefore well able to endure hardship. I do not know what his other qualifications were."
The last sentence is very pregnant, and implies that a very poor opinion of the men as experienced bushmen was entertained by those who saw them.
The lost expedition is supposed to have consisted of six whites and two blacks; the names known being those of the doctor himself, Classen, Hentig, Stuart, and Kelly. He had with him 12 horses, 13 mules, 50 bullocks, and 270 goats; beside the utterly inadequate allowance of 800 pounds of flour, 120 pounds of tea, some sugar and salt, 250 pounds of shot, and 40 pounds of powder. His last letter is dated the 3rd of April, 1848, from McPherson's station on the Cogoon, but in it he speaks only of the country he has passed through, and nothing of his intended route. Since the residents of this then outlying station lost sight of him, no sure clue as to the fate of him and his companions has ever come to light. The total evanishment, not alone of the men, but of the animals -- especially the mules and the goats -- is one of the strangest mysteries of our mysterious interior. Thirst probably caused the death of the animals, and in that case they would have died singly and apart, and their remains would in after years elude attention. A similar fate probably befel the men.
Rumour has always been rife as to the locality of Leichhardt's death, and suggestions the most hopelessly unlikely and inconsistent have been put forward and seriously considered. At the same time, the only two reliable marks, undoubtedly genuine and fitting in in every way with Leichhardt's projected course of travel, have been neglected.
Leichhardt started from McPherson's station on the Cogoon, now perhaps better known as Muckadilla Creek. There was a rumour, never authenticated, that after he had proceeded nearly one hundred miles he sent back a man with a report that he had passed through some splendid pastoral land, but this is not at all likely to be true. The first indication of him is then met with on the Barcoo (Victoria) whereon A.C. Gregory, in charge of the Leichhardt Search Expedition, in 1858, found his marked tree and other indications:--
"Continuing our route along the river (latitude 24 degrees 35 minutes; longitude 36 degrees 6 minutes), we discovered a Moreton Bay ash, about two feet in diameter, marked with the letter L on the east side, cut through the bark about four feet from the ground, and near it the stumps of some small trees that had been cut with a sharp axe, also a deep notch cut in the side of a sloping tree, apparently to support the ridge-pole of a tent, or some similar purpose; all indicating that a camp had been established here by Leichhardt's party. No traces of stock could be found; this however is easily accounted for, as the country had been inundated last season."
There can be little doubt about the authenticity of the trace, and it at once does away with the truth of the stories told to Hovenden Hely by the blacks as to Leichhardt's murder on the Warrego River. Gregory then went up the Thomson River but found no other mark, and returning followed that river and Cooper's Creek down to South Australia. This camp of Leichhardt's is easily understood. Then follows an account of the other found by the same explorer in 1856, during an earlier expedition. This was on the upper waters of Elsey Creek, and his description of it runs as follows:--
"The smoke of bush fires was visible to the south, east, and north, and several trees cut with iron axes were noticed near the camp. There were also the remains of a hut, and the ashes of a large fire, indicating that there had been a party encamped there for several weeks; several trees from six to eight inches in diameter had been cut down with iron axes in fair condition, and the hut built by cutting notches in standing trees and resting a large pole therein for a ridge. This hut had been burnt apparently by the subsequent bush fires; and only some pieces of the thickest timber remained unconsumed. Search was made for marked trees, but none were found, nor were there any fragments of iron, leather, or other material of the equipment of an exploring party, or of any bones of animals other than those common to Australia. Had an exploring party been destroyed there, there would most likely be some indications, and it may therefore be inferred that the party proceeded on its journey. It could not have been a camp of Leichhardt's in 1845, as it is 100 miles south-west of his route to Port Essington, and it was only six or seven years old, judging by the growth of the trees; having subsequently seen some of Leichhardt's camps on the Burdekin, Mackenzie, and Barcoo Rivers, a great similarity was observed in the mode of building the hut, and its relative position with regard to the fire and water supply, and the position with regard to the great features of the country was exactly where a party going westward would first receive a check from the waterless tableland between the Roper and Victoria Rivers, and would probably camp and reconnoitre before attempting to cross to the north-west coast."
Leichhardt's track, as far as the Elsey, seems tolerably plain and entirely in accordance with the character of the man and his intentions. Forced to retreat from the dry country west of the Thomson, he probably followed that river to its head, and crossing the main watershed regained and re-pursued his track of 1845, as far as the Roper, of which river Elsey Creek is a tributary. When he left the camp seen by Gregory, he would, going either south-west or west, find himself in the driest of dry country, which is even now but sparsely settled. And there came the end.
