At length the Barbarossas resolved to quit Tunis and Jerba, for they had now chosen to settle at Jijil, sixty miles to the east of Bujeya. Their fame had come before them; the inhabitants were proud to welcome the brother corsairs who had done many wonderful things by land and sea, and before long the elder Barbarossa was chosen as their Sultan. In 1516 died Ferdinand, and about this time the Algerine Moors declined any longer to pay tribute to Spain. To Barbarossa came an invitation to aid these inhabitants of Algiers in driving the Spanish garrison from their fort. The invitation was accepted, 6000 men and sixteen galliots were got together. Arrived before the fortress of Algiers, Barbarossa offered a safe conduct to the garrison if they would surrender, but the latter’s reply was merely to remind the corsair of Bujeya. Then for twenty days Barbarossa battered away at the fortress, but without making a breach, and meanwhile the Moors began to regret that they had asked the red beard to aid them. But it would be less easy to turn them out now that once these dare-devils had set foot on their territory. Barbarossa knew this and waxed insolent. The Algerines made common cause with the soldiers in the fortress, and a general rising against the red beard was planned. But they had reckoned without their guest. For Barbarossa had spies at work and became informed of this plot. Whilst at prayers one Friday in the mosque, Barbarossa had the gates closed, the conspirators brought before him one by one, and then after twenty-two of them had been put to death there was an end to this plotting against the corsair of Lesbos. Barbarossa increased in power, in the number of his galleys, in the extent of his territory and in the number of his subjects, so that by now he had become Sultan of Middle Barbary. Practically the whole of that territory marked on our modern maps of Algeria was under his sway. Step by step, leaping from one success to another, ignoring his occasional reverses, he had risen from a mere common pirate to the rank of a powerful Sultan. So potent had he become, in fact, that he was able to make treaties with other Barbarian Sultans, and all the summer season his galleys were scouring the seas bringing back increased wealth and more unfortunate Christian prisoners. Richly laden merchant ships from Genoa, from Naples, from Venice, from Spain set forth from home, and neither the ships nor their contents were ever permitted to return or to reach their ports of destination.
