But notwithstanding the friendly disposition of the natives Rupert could not prolong his stay in the river. The time of the tornadoes--May to July--was drawing near, and preparation was necessary. The Princes therefore broke up {258} their Spanish prize, as unfit for service, bequeathed her guns to the Courlanders, and sailed for the Cape de Verd Islands. By the way some of their ships were missed, and they anchored on the coast to await them. During the delay, the natives stole away one of Maurice's sailors, and Maurice, finding fair words unavailing, sent a force, under Holmes, to recover him. The two boats, in which Holmes and his men were embarked, were overturned in the surf, and lost at their landing, but happily, the liberated negro, Jacus, came to their help with a party of his friends. Then Maurice sent a third boat to bring his men back, but with orders not to land unless Jacus advised it. Holmes and his force were safely re-embarked, when the captain of the boat, mistaking Maurice's orders, declared that they were to take Jacus back with them. On hearing this, Holmes went once more on shore, to speak to Jacus, and, during the delay involved, the hostile negroes began to attack the crew. The sailors shot a negro, and captured one of their canoes, which so incensed the rest that they seized upon Holmes and another man who had accompanied him. The men in Maurice's boat saw themselves outnumbered, and returned in all haste to their ship, with the bad news. Both Princes were "extremely moved," and, swearing that they would rescue their comrades or perish in the attempt, they went ashore to treat with the natives. The negroes declared, through Jacus, that they would release Holmes if their canoe were returned, and the men in her set at liberty. Rupert at once signalled to the Vice-Admiral to free the canoe, but no sooner was it done than Jacus came running down to the shore, with the news that his countrymen intended treachery, and would not release their prisoners. It proved too late to re-take the canoe, but the Prince fired on the natives, who were gathering round him, and signalled all his ships to send men to his aid. The natives fought with much courage; and Rupert himself was wounded by a poisoned arrow, which he instantly cut out with his knife. {259} While he engaged the attention of the hostile negroes, Jacus and his friends contrived to free Holmes and his comrade, and to embark them safely in Maurice's pinnace. This done, the Princes retreated to their fleet; but they did not show themselves ungrateful to Jacus, "whose fidelity," says one of the crew, "may teach us that heathens are not void of moral honesty." On the day following, Rupert sent his thanks, and an offer to take Jacus with him and "to reward him for his faith and pains." But Jacus, wishing the Princes all good luck, declined their offer; he was, he said, not in the least afraid to remain with his own tribe.[40]
