At this juncture Barbarossa hesitated; had he not done so, and had he followed Grimani to Corfu, he might have destroyed both him and Vincenzo Capello in detail before the arrival of Doria. The Prevesa campaign is a curious study of hesitation on both sides, and the idea naturally occurs were not the corsair and the Christian commanders-in-chief too old for the work on which they were engaged? Men of over seventy are not impetuous, but grave and deliberate as a rule; but there is no rule without its exceptions, and Doria and Barbarossa were not as other leaders. Up to the present their dash and initiative had been unimpaired. There was no question that Barbarossa not only made a mistake in hesitating, but that by it he lost the game. Instead of striking at once he did what he had never done before in the whole of his career, which was to send to Constantinople for instructions. Some of his galleys had captured a fishing-boat off Corfu, the crew of which had seen Doria’s fleet. The Moslem leader sent the fishermen themselves to report to Soliman exactly what they had seen, and to ask for and bring back instructions from that potentate. What Barbarossa had discovered was that the odds were very much against him; so much, in fact, that he would have to act on the defensive. In consequence, he steered for Prevesa and entered the Gulf of Arta, which is approached by a long narrow strait, dominated by the castle of Prevesa. Once inside he anchored his galleys in such a position that they could fire direct out to sea, thus overwhelming with their fire any vessel attempting to enter. Barbarossa now occupied the same position as did Octavius in his combat with Antony. The rôle of the latter general was now taken by Doria. Antony, like Doria, had heavy ships which could not advance to the attack owing to their too great draught. Octavius, with his light-draught ships, could both attack and retreat into safety if overmatched. On September 22nd Doria, having collected all his ships, gave orders to fill up with wood, water, and fresh provisions. On the 25th, to the sound of the trumpet, the Commander-in-Chief, with his fleet of two hundred sail, weighed anchor and sped before the wind rapidly southwards. Grimani commanded the advance-guard, Doria was in the centre, Vincenzo Capello, with his Venetians, brought up the rear. Formed in two columns, the nefs followed the galleys; the _Galleon of Venice_, commanded by Condalmiero, a squadron in herself, preceded them. [Illustration: GALEASSE UNDER SAIL.] From the anchorage at Corfu to the entrance of the Gulf of Arta is about fifty-eight miles, and, traversing this distance during the hours of daylight, the fleet anchored, as night fell, under Cape Prevesa. The Galleon which acted as what we should now call the guide of the fleet, anchored in sixteen feet of water, which was barely sufficient to keep her afloat.
