A rush of water came up the gangway, and the crew were thrown against the bulwarks, and then into the sea. The life-preservers helped to keep them afloat, but when they looked for the life-boat they found that it had been carried away. A catamaran was the largest piece of floating wreckage, and they swam to this. The firing had now stopped. The wreckage began to drift away, and the crew were left swimming about the catamaran, apparently unseen by the enemy. The men were ordered to cling to this rude craft, their bodies in the water, their heads hidden by the boards, and to keep quiet, as Spanish boats were passing close to them. All the crew were safe, and Hobson expected that in time some Spanish officers would come out to reconnoiter the channel. He knew that his men could not swim against the tide to the harbor entrance, and even had they been able to do so it would have been too dangerous a risk, as the banks were now lined with soldiers, and the water patrolled by small boats. Their hope lay in surrendering before they were fired upon. The moon had now nearly set, and the shadow of the high banks fell across the water. Boats rowed by Spanish sailors pulled close to the catamaran; but acting under orders from their commander the crew of the _Merrimac_ kept well out of sight. The sun rose, and a new day came. Soon the crew could see the line of distant mountains, and the steep slopes leading to Morro Castle. A Spanish torpedo-destroyer was heading up the harbor, and a bugle at one of the batteries could be heard across the waters. Still the Americans clung to the catamaran, although their teeth were chattering, and they had to work their arms and legs to keep warm. [Illustration: SPANISH BOATS PULLED CLOSE TO THEM] Presently one of the men said, "A steam-launch is heading for us, sir!" The commander looked about, and saw a large launch, the curtains aft drawn down, coming from around a point of land straight toward the catamaran. As it drew near the launch swerved to the left. When it was about thirty yards away Hobson hailed it. The boat instantly stopped and began to back, while some riflemen appeared on the deck and took position for firing. No shot followed, however. Hobson called out again, asking whether there were any officers on the boat, and adding that if there were he was ready to surrender himself and his American sailors as prisoners of war. The curtain at the stern was lowered, a Spanish officer gave an order, and the rifles dropped. The American commander swam to the launch, and climbed on board, being helped up by the Spanish officer, who turned out later to be no other than Admiral Cervera himself. Hobson surrendered for himself and his crew. The launch then drew close to the catamaran, and the sailors clinging to it were pulled on board. Although the Spaniards knew that the _Merrimac's_ men had bottled up their war-ships in the harbor, they could not help praising their bravery.
