At daybreak the next morning this launch opened a most unexpected fire on the French column, and compelled it to change its route, so that when they took the Nazareth road they became exposed to the attacks of the Samaritan Arabs. The guns of the British ships preventing the French from making an attack from the north, they invested Acre on the northeast side, where the defences were much stronger. As no artillery was used in replying to the British boats, it was evident that the French had none with them. Expecting that a flotilla was to bring artillery up to them, a lookout was kept, and, on the morning of the 18th a French corvette and nine sail of gun vessels was seen from the Tigre. They were promptly chased and the gun-boats taken, but the corvette escaped. The prizes were full of battering cannon, ammunition and siege stores, which they had brought from Damietta. These guns, which had been intended for the destruction of Acre, were now landed for its defence, and the gun-boats employed to harass their late owners, and cut off supplies. That same day an English boat expedition met with a disastrous repulse in an attack upon four French transports, which had come into Caïffa anchorage with supplies for the French army, losing heavily in officers and men; and soon after all the English vessels were obliged to put to sea, on account of bad weather, and were not able to return again until the 6th of April. In the meantime Bonaparte had been pushing the siege operations with the energy peculiarly his own, and it seemed impossible for the Turkish garrison and the English sailors to resist his determined approach. During the absence of the British ships he had pushed his approaches to the counter-scarp, and in the ditch at the northeast angle of the town was mining the towers to widen a breach already made by his field pieces. As much danger was apprehended from this approach, a sortie was determined on, in which the English seamen and marines were to bear a prominent part. They were to force their way into the mine while the Turks attacked the enemy’s trenches on the right and left. The sortie took place just before daylight, but the Turks rendered abortive the attempt to surprise the enemy by their noise and impetuosity. The English sailors, armed with pikes and cutlasses, succeeded in entering the mine, and destroyed its supports, and partly filled it up. The marines supported and protected them while doing this, and the party was covered on its return by a cross fire from one of the ships. This sortie much delayed Bonaparte’s operations; but, in the meantime, Rear-Admiral Perrée of the French navy, who had been hovering about the coast with a squadron, succeeded in landing supplies and some 18-lb guns, at Jaffa, which were immediately brought up, overland. Napoleon attached the utmost importance to the speedy capture of Acre, which was necessary to the success of his plans, and he pushed the siege with
