When they had gone Misson returned to the work of improving his town, and gave the command of his ship, the _Victoire_, to Tew, who, with one hundred and sixty picked fellows, set out to sweep the seas. He sailed down the wind to the coast of Zanzibar, and off Quiloa made up to a large ship which backed her main-topsail and laid by for him. Tew engaged her for four hours, losing many men, but finding her a Portuguese public ship of fifty guns and three hundred men, much more than a match for the little _Victoire_, he attempted to make off. The _Victoire_, however, was so foul from her long service that she could not show her customary clean pair of heels, and the stranger, proving fast and weatherly, drew up with her. The Portuguese Captain, a gallant officer of great height and herculean strength, lay alongside the _Victoire_ and boarded her at the head of his men; but the pirates, not used to being attacked, and expecting no quarter, made so desperate a resistance that they not only drove back the enemy with loss, but were enabled to board in their turn. At first only a few followed the Portuguese as they leaped back into their own ship; but Tew, perceiving the desperate resolution of these, sang out, “Follow me, lads!” and sprang over his enemy’s rail. The Portuguese opposed the pirates firmly for a time, but to Tew’s cry, “She’s our own! Board her! Board her!” his men replied in continually augmenting numbers, and drove the defenders back to the main-hatch. Here a bloody conflict ensued, for the Portuguese Captain fought in the front rank of his men, and with voice and example encouraged them to combat. Seeing this, Tew rushed forward to meet him, and the two captains crossed swords with equal bravery. The crews paused to observe the duel, and watched with fiercely excited eyes the flashing sabres and shifting poises of their champions. The Portuguese had a longer reach, and was much taller and stronger than the pirate, but the latter had the agility of a panther, and was noted as one of the best swordsmen of his day. Time and again the Portuguese made a dash against his adversary with point or blade, only to be met with an accurate parry or a quick return stroke that forced him backward nearer and nearer to the open hatch. Finally Tew parried a furious lunge and delivered his terrible return stroke on the neck of the Portuguese, who threw up his hands and fell backward down the hatch. This ended the fight, and the crew of the public ship called for quarter. With his rich prize, which yielded him one hundred thousand pounds in Spanish gold, Tew put back to port, where, notwithstanding his severe loss, his courage and dash were loudly acclaimed by the colony. Caraccioli persuaded two hundred and ten of the Portuguese to join the Libertaitans, and among them, to Misson’s great pleasure, was found a school-master, whose services he at once devoted to the instruction of his negroes.
