As the British vessels reached the head of the French ships they anchored one after another, each laying itself broadside to broadside against an opponent, and the battle commenced with terrible energy, the tremendous roar of the guns astounding the Arabs who were gathered on the sand-hills. At first the French reply was feeble. They were taken entirely by surprise by Nelson's manoeuvre. Believing that he could only attack them from outside, they had prepared only on that hand for the fight, and in clearing the decks for action all the useless gear and fittings had been piled over on the other side, and it was some little time before this could be cleared away and the guns got ready for action. Then for a time their fire was as heavy as that of the British. Nevertheless some of them had suffered terribly before they were able to return a shot, and this contributed in no small degree to the British victory.
