This family consisted of Mr. Wolston, a mechanical engineer, his wife, Merry Wolston, and his two daughters Hannah and Dolly, aged seventeen and fourteen, respectively. Mr. and Mrs. Wolston also had a son, James, who at this time was living in Cape Town with his wife and young son.

 

            The Unicorn had left Sydney harbour in July, 1816, and after skirting the southern coast of Australia had turned her course towards the northeast waters of the Indian Ocean.

 

            Lieutenant Littlestone had been ordered by the Admiralty to cruise about these latitudes and endeavour to find, either upon the western coast of Australia or in the neighbouring islands, traces of the existence of any survivors of the Dorcas, of whom no news had been heard for two and a half years.

 

            It was not known precisely where the wreck had occurred, although there was no doubt about the catastrophe, since the second mate and three men of the crew had been picked up at sea and taken to Sydney, only those four out of all who were in the ship's longboat. As for Captain Greenfield, the sailors and the passengers—the daughter of Colonel Montrose among them—it would have been difficult to cherish any hope of their recovery after the story told of the wreck by the second mate. However, the British Government had desired that further search should be made in this portion of the Indian Ocean as well as in the approaches to the Timor Sea. There are many islands there not much frequented by trading vessels, and it was desirable to pay a visit to those in the neighbourhood of the seas where the Dorcas had probably been lost.

 

            So, after doubling Cape Leeuwin, at the southwest extremity of Australia, the Unicorn had borne northwards. She touched at a few of the Sunday Islands without result, and resumed her journey to the Cape. It was then that she met with a succession of violent storms against which she had to struggle for a whole week, sustaining serious damage, which compelled her to seek some anchorage for repairs.

 

            On the 8th of October the lookout descried to the southward a land—in all probability an island—which was not marked in the latest charts. Lieutenant Littlestone steered for this land and found refuge in the heart of a bay on its eastern coast which was completely sheltered from adverse winds and offered an excellent anchorage.

 

            The crew set to work at once. Tents were pitched on the beach at the foot of the cliff. A regular camp was arranged, and every precaution taken that prudence dictated. It was quite possible that this coast was inhabited or visited by savages, and as everybody knows the natives of the Indian Ocean have an evil reputation.

 

            The Unicorn had been at her moorings for two days when, on the morning of the 10th of October, the attention of the commander and the crew was arrested by a double detonation coming from the west.

 

            This double report was entitled to a reply, and the Unicorn answered with the discharge of three guns from her port side.

 

            Lieutenant Littlestone could do nothing but wait. His ship, being still in dock undergoing repair, could not have got under way and rounded the cape on the north-east. Several days were required before she would be in a condition to put to sea. And in any case, he assumed that the corvette's guns had been heard, since the wind was blowing off the sea, and he quite expected to see some ship come within sight of the bay at any moment.

 

            So lookout men were posted at the mast-head. Evening came yet no sail had appeared. The sea to the north was absolutely deserted, as was that portion of the coast bounded by the bend of the bay. As for landing a detachment of men and sending it to reconnoitre, Lieutenant Littlestone decided not to do this from prudential considerations. Besides, the circumstances did not appear to demand it imperatively. Directly the Unicorn was in a fit state to leave her moorings she would follow round the coastline of this land, whose precise position had now been definitely fixed as latitude 19°30', longitude 114°5' east of the meridian of Ferro Island which belongs to the Canary Islands group in the Atlantic Ocean.

 

            Three days passed without anything fresh happening, except, indeed, a violent storm, which caused wide and profound disturbance but left the Unicorn unharmed under the protection of the coast.

 

            On the 13th of October several reports of cannon were heard from the same direction as the former ones.

 

            To this fire, each discharge of which was separated by an interval of two minutes, the Unicorn replied with seven guns fired at equal intervals. Inasmuch as the new reports did not seem to come from any nearer point than those which had preceded them, the commander concluded that the ship whence they proceeded could not have changed her position in the meantime.

 

            On this same day, about four o'clock in the afternoon, Lieutenant Littlestone, while pacing the bridge with his spyglass in use, caught sight of a little boat. Manned by two men, it was gliding between the rocks, coming from the promontory. These men, who were black-skinned, could only be Malay or Australian aborigines. Their presence was proof that this portion of the coast was inhabited, and accordingly steps were taken to be prepared for an attack, an eventuality always to be feared in these waters of the Indian Ocean.

 

            However, the canoe drew near, a craft resembling an Esquimau kayak. It was allowed to approach. But when it was within three cables' length of the corvette, the two savages spoke in a language which was absolutely unintelligible.

 

            Lieutenant Littlestone and his officers waved their handkerchiefs and held up their hands to show that they were unarmed. But the canoe showed no disposition to draw nearer. A moment later it sped rapidly away, to disappear behind the promontory.

 

            At nightfall Lieutenant Littlestone took counsel with his officers as to sending the ship's longboat to reconnoitre the northern coast. The situation was certainly one which required to be cleared up. It could not have been the aborigines who had fired the guns which had been heard in the morning.
