However, it was soon ascertained that the enemy at the time was not clear of the town and a light battery at Le Coq opened fire on the ships. Two shells, falling on the beach close to a crowd, excited the inhabitants. A heavy battery of four guns in the direction of Zeebrugge opened fire on the destroyers, and, as it seemed possible the presence of the naval force might lead to the bombardment of Ostend or to more shells falling in the town, where they would endanger the lives of civilians, the British decided to withdraw the naval force, and thus give the enemy no excuse for firing toward the town. They, therefore, reembarked and the destroyers withdrew, being heavily shelled, to just east of Middelkerke. Four motor launches were left at Ostend as an inshore patrol, the inhabitants being nervous of the Germans returning. The King and Queen of the Belgians expressed the wish to visit Ostend, either from the sea or the air. In view of the difficulty of landing and the uncertainty of the situation, they proceeded in the destroyer _Termagant_, flying the Belgian flag at the main, to the vicinity of Ostend. The senior officer of the British motor-launch patrol off Ostend, which had been reenforced by French motor launches, reported that all had been quiet for some hours. Their majesties therefore landed and proceeded to the Hôtel de Ville. They were received everywhere with indescribable enthusiasm. They returned to Dunkirk about 10 o'clock at night. The British naval forces suffered no damage and no casualties. In the morning of November 1, 1918, after the Austrian fleet had been surrendered to the Jugoslav National Committee, Commander Rossetti and Lieutenant Paolucci of the Italian navy succeeded in entering the inner harbor of Pola and sank the large battleship _Viribus Unitis_, flagship of the Austro-Hungarian fleet. This daring enterprise was accomplished by the use of a so-called "navy tank" which succeeded in penetrating the mine field at the entrance to the harbor. This was described by naval officials as a small vessel, similar to the "Eagle boats" being built for the United States navy. During this period the Italian navy also was active in the occupation of Austro-Hungarian ports on the Adriatic. Thus Italian battleships entered the ports of Zara and Lussinpiccolo and raised the Italian flag there. Zara is a seaport of Austria-Hungary and is the capital of Dalmatia. It is situated on a promontory on the eastern coast of the Adriatic, 170 miles southeast of Venice. Lussinpiccolo is a town on an island belonging to the Crownland of Istria. It is the principal seaport of the Quarnero Islands, between Istria and the Croatian Coast.
