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 role 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.

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.

The Gulf of Arta, in which, as we have said, the fleet of the Moslems were now anchored, presents very curious physical peculiarities:  it is twenty-two miles in length from east to west, and fifteen miles in breadth from north to south.  This sheet of water is formed into an immense bay by the configuration of the land, and its depth, in places, is from one hundred and thirty to two hundred feet.  Inside it all the navies in the world might ride at anchor, were it not for the fact that the entrance is closed by a bar upon which the depth varies from six and a half to thirteen feet.  With his light-draught ships Barbarossa occupied the interior position, while the heavy ships of Doria must in any event remain outside.  A strong sea-breeze was blowing on shore; all night the nefs and the galleys were nearly rolling their gunwales under.  In these packed and crowded vessels the misery and discomfort of their crews may be imagined.  On the morning of the 26th, however, the west wind dropped, and a light wind sprang up from the northward.
