The expedition started under the leadership of Robert O'Hara Burke, who began his career as a cadet at Woolwich, but left at an early age to enter a regiment of Hussars in the Austrian service, in which he subsequently held a captaincy. When this regiment was disbanded, in 1848, he obtained an appointment in the Irish Constabulary, which he exchanged for the Police Force of Victoria in 1853, and in this he was at once made an inspector. A Mr. Landells, in charge of the camels, went as second in command, and William John Wills, an astronomer and surveyor, as third. Wills was the son of Dr. William Wills, and was born at Totnes, in Devonshire, in 1834; he was cousin to Lieutenant Le Viscomte, who perished with Sir John Franklin in the 'Erebus.' In 1852 the news of the wonderful gold discoveries induced him to try his fortune in Victoria; but he soon became attached to the staff of the Melbourne Observatory, where he remained until selected for the post of observer and surveyor to the exploring expedition. From the time that the expedition first took shape the names of these leaders were associated in the minds of the people with those of other brave men who had toiled to solve the mystery that lay out in the great thirsty wilderness of the interior. Some of them had tried, and, failing, had returned broken in health by the terrible privations they had met with. Others, having failed, had tried again; but the seasons and years had rolled on since, and had brought back no story of their fate. Therefore, as late in the afternoon Burke, mounted on a pretty grey, rode forth at the head of the caravan, cheer after cheer rang out from either side of the long lane formed by the thousands of sympathetic colonists who were eager to get a last glimpse of the adventurers. Immediately following the leader came a number of pack horses led by the European servants on foot; then Landells and Dr. Beckler mounted on camels; and in their train sepoys, leading two by two twenty-four camels, each heavily burdened with forage and provisions, and a mounted sepoy brought up the rear. At intervals after these several wagons rolled past, and finally when nearly dusk, Wills and Fergusson, the foreman, rode out to their first camping-ground at the village of Essendon, about seven miles distant. Before the evening star, following close the crescent moon, had dropped below the dark and distant hill range, the green near the church was crowded by the picturesque confusion of the camp. Above the fires of piled gum-tree bark and sticks rose soft plumes of white smoke that scented the air fragrantly, and the red light of the flames showed, as they would show many times again, the explorers' tents in vivid relief against the coming night.
