Just as day began to break, the gates were opened, and the columns moved out one after the other. The order that the strictest silence was to be observed was obeyed by the sailors and marines; but the Turks, who were wrought up to a pitch of enthusiasm, made so great a noise that the moment they issued from the gate shots were fired by the advanced pickets, and a few seconds later the roll of drums in the French lines broke out, and it was clear that the whole camp was alarmed. Sir Sidney Smith uttered an exclamation of anger. As concealment was useless, he then sent the two midshipmen to order all the batteries to open fire upon the French trenches, and as the first gun boomed out the ships and gun-boats on both flanks also opened fire, and the trenches by which the French must advance from the village were swept by a storm of shot. The French batteries joined in the din, while the infantry in the advanced trenches opened a heavy musketry fire.
