An hour passed, and then two or three officers were seen coming down from the hill; one went up to General Hill, who happened at that moment to be talking to Colonel Tritton. "You are to prepare to cross, sir, Colonel Waters has discovered a small boat brought across by a Portuguese in the night. They are going to cross to that great convent you see upon the other side. They will bring back boats with them, and you will cross at once, take possession of the convent, and hold it against any force that may be brought against you until reinforcements arrive." Very quickly were the orders passed, and with a smile of satisfaction the men took their arms and fell in. They were moved near the river, and kept under shelter of some houses. "Keep near me," Colonel Tritton said to Tom and Peter, "I may want you to carry messages, there will be no sounding of bugles to-day." Keeping under the shade of some trees so that they could command a view of the river without being seen from the opposite side, Colonel Tritton with two of his officers and his two buglers, watched what was going on. A few paces ahead of them were Generals Paget and Hill, like themselves, watching the daring experiment. Behind, under shelter of the houses, were the troops in dense masses. The Rangers, as the first regiment in General Hill's division, were in front, and would naturally be the first to cross. It was a most anxious moment, as Colonel Waters and two Portuguese pushed the tiny boat from shore and pulled across stream. The bulk of the Serra Hill hid the river at this point, and even the convent opposite, from the sight of the French army formed up below the town, but there were no doubt stragglers all over the city, and the whole baggage of the French army was in retreat by the road to Valarga which ran at a short distance behind the convent. Most anxiously their eyes were strained upon the opposite bank, from which they expected to see the flash of musketry, as the little boat neared the convent. All, however, was as still as death. Behind them they heard a rumble, and looking round saw eighteen guns on their way up the hill. From this eminence they could command the ground around the Seminary, as the convent across the water was called, and thus afford some aid to the troops as they crossed. There was a murmur of satisfaction as the boat neared the opposite shore, and after lying still for a moment to reconnoiter the convent, pulled boldly up to the landing-place, where its occupants disembarked and entered the Seminary. Their absence was not long. In a few minutes they reappeared with eight or ten men, and then at once entered and cast off three large boats moored along side. The boys could hardly repress a cheer as they saw them fairly under weigh. An officer now left the side of the General, and came to Colonel Tritton, "You will get your first company in readiness to embark, sir; do not let them show themselves until the last moment."
