Joseph Hawkey, of Liskeard, and his wife Amye, daughter of the Rev. John Lyne, had a numerous family. John was the eldest son, born at Liskeard in 1780; the other sons were William, Joseph, Richard, and Charles. There was also a daughter Charlotte, born at Liskeard 10th May, 1799.
Lieutenant Joseph Hawkey, r.n., born at Liskeard in 1786, was killed in action while commanding a successful attack on a Russian flotilla in the Gulf of Finland in 1809.
John also entered the navy, as midshipman in the Minerva. A few months after the renewal of the war in 1803 he was taken prisoner whilst gallantly defending that ship, when she was unfortunately run by the pilot, during a dense fog, on the west point of the stone dyke of Cherbourg. Hawkey remained in captivity at Verdun for eleven years, till 1814.
A commission of lieutenant had been sent out to him by mistake to the West Indies, which being dated previous to his capture was not cancelled, but forwarded to him in France, and was thus the means in some degree of alleviating the evils of captivity. Whilst at Verdun he made the acquaintance of Lieutenant Tuckey, r.n., a person like himself a prisoner, and like him of fine taste and considerable talents.
His prospects had been cruelly clouded by his long detention in captivity, and on the conclusion of peace he at once joined the Cyrus, sloop of war; but when the Government proposed to send out an expedition to explore the Zaire or Congo, and appointed Tuckey in command, Lieutenant Hawkey eagerly accepted the invitation of his friend to join him and act as second in command.
At this time little was known of the Congo and the Niger. Hitherto what was known was due to Arabian writers of the Middle Ages, and to what leaked out from the Portuguese; but these latter, who carried on an extensive slave trade thence, did their utmost to keep their knowledge of these rivers to themselves. But even they were not well acquainted with the rivers far up from their mouths. Mungo Park was preparing for his second expedition to explore the Niger, and it was even supposed that the Congo or Zaire that flows into the South Atlantic was an outlet of the Niger, and not an independent river; and this opinion was warmly expounded by Park in a memoir addressed to Lord Camden previous to his departure from England, and he added that, if this should turn out to be a fact, "considered in a commercial point of view, it is second only to the discovery of the Cape of Good Hope; and, in a geographical point of view, it is certainly the greatest discovery that remains to be made in this world."
On March 19th, 1816, the Congo, accompanied by the Dorothy transport, sailed on a voyage of exploration to the Zaire. The Congo was about ninety tons, schooner rigged, and drew five feet of water. She was fitted up entirely for the accommodation of officers and men, and for the reception of the objects of natural history which might be collected on her progress up the river. The gentlemen engaged on the expedition, in the scientific department, were: Professor Smith, of Christiania, botanist and geologist; Mr. Tudor, comparative anatomist; Mr. Cranch, collector of objects of natural history; and a gardener to gather plants and seeds for Kew; also Mr. Galway, a gentleman volunteer. There were two negroes, who would serve as interpreters, one of whom came from eight hundred miles up the Zaire. The officers were: Captain Tuckey, Lieutenant Hawkey, Mr. Fitzmaurice, master and surveyor, Mr. McKernow, assistant surgeon, two master's mates, and a purser. In addition to the Congo, the transport took out two double whale-boats, so fitted as to be able to carry eighteen to twenty men, with three months' provisions.
Lieutenant Hawkey was an excellent draughtsman; he sketched in a bold and artistic manner, and to a general knowledge of natural history he united the talent of painting the minutest sea and land animals with great spirit and accuracy.
Although the vessels sailed from Deptford on February 16th, they were detained in the Channel and at Falmouth by westerly gales till March 19th. On April 9th they reached the Cape de Verd Islands, whence he wrote home to his sister Charlotte:—
