Example Input: Passage: For the rest of her long career, Ancona served in a variety of roles, both in the main fleet and in Italy's colonial empire. After the end of the war, the government lost confidence in the fleet and drastically reduced the naval budget. The cuts were so severe that the fleet had great difficulty in mobilizing its ironclad squadron to attack the port of Civitavecchia in September 1870, as part of the wars of Italian unification. Instead, the ships were laid up and the sailors conscripted to man them were sent home. Some time after 1866, the ship was rebuilt as a central battery ship, with most of her guns located in a central, armored casemate. Two other guns were placed in the bow as chase guns, with a third mounted as a stern chaser. At around 1871, her armament was also revised, to two guns in the bow and eight 8 in guns, four on each broadside and the last in the stern. Later, her armament was changed again, to eight guns, six guns, four quick firing (QF) guns, and two Hotchkiss revolver cannons. Ancona was stricken from the naval register in 1903 and then broken up for scrap.
