The main British fleet at that time was in the Atlantic outside Cadiz, but the admiral had detached a force of his best ships, under Vice-Admiral Nelson—a man certainly as great a genius in naval affairs as was Napoleon in things military—to chase and engage the French flotilla.^[1] For a time Nelson sought the French fleet in vain; finally, on the evening of the first of August, he found it at anchor in Aboukir Bay. He had caught it unawares; many of the men were ashore and a council was being held in the flagship. He had no charts, and it was a hazardous thing to sail into the shallow water in a bad light. The French admiral concluded, therefore, that he would not attack before morning, and so made no haste in recalling his men aboard until it was too late to do so. Nelson struck at once—against the advice of some of his captains. One ship only went aground. She marked the shoal for the rest of the fleet. He sailed to the attack in a double line about sundown, putting the French between two fires. Night fell as the battle was joined; the fight thundered and crashed in the darkness, until it was lit presently by the flames of burning French ships, and then by the flare of the French flag-ship, the Orient, blowing up.... Before midnight the battle of the Nile was over, and Napoleon's fleet was destroyed. Napoleon was cut off from France.
