on 27–29 March. For most of the daytime engagement, ''Zara'' and the rest of the 1st Division were stationed on the disengaged side of the Italian fleet, and so did not see action during this phase. ''Vittorio Veneto'' was torpedoed by British aircraft from the carrier and was forced to withdraw, and the 1st Division remained on the port side of the Italian fleet to screen against another possible British attack. A second British airstrike later on the 28th failed to locate the retiring ''Vittorio Veneto'' and instead scored a single torpedo strike on ''Pola'', hitting her
amidships on her starboard side. In the confusion of the attack, ''Pola'' had nearly collided with ''Fiume'' and had been forced to stop, which had prevented her from taking evasive action. The damage filled three compartments with water and disabled five of her boilers and the main steam line that fed the turbines, leaving her immobilized.
Admiral Iachino, the fleet commander, was unaware of ''Pola''s plight until 20:10; upon learning of the situation he detached ''Zara'', ''Fiume'', and four destroyers to protect ''Pola''. At around the same time, the British cruiser detected ''Pola'' on her radar and reported her location. The British fleet, centered on the battleships , , and , was at this point only away. The British ships, guided by radar, closed in on the Italians; at 22:10, ''Pola'' was about from ''Valiant''. Lookouts on the crippled Italian cruiser spotted shapes approaching and assumed them to be friendly vessels, so they fired a red flare to guide them. Almost twenty minutes later, the British illuminated first ''Zara'' and then ''Fiume'' with their searchlights; the British battleships obliterated ''Zara'', ''Fiume'', and two destroyers in a point-blank engagement. ''Zara'' had been hit by four
broadsides from ''Warspite'' and five more from ''Valiant'' in the span of just a few minutes. The destroyer launched torpedoes at the crippled ''Zara'' and scored at least one hit. The destroyer launched four more torpedoes with unknown results.
The British battleships then turned away to avoid a torpedo attack from the remaining destroyers. ''Zara'', by now burning furiously, remained afloat and drifted near the immobilized ''Pola''. ''Zara''s commander decided at 02:00 that his ship could not be saved, and so ordered the crew to
scuttle the ship. At around the same time, the destroyer arrived on the scene and fired three torpedoes at ''Zara''. The demolition charges exploded in the magazines at 02:30, and within ten minutes, the ship capsized and sank. Most of her crew, some 783 men including Cattaneo, were killed in the sinking. ''Zara'' was formally stricken from the
naval register on 18 October 1946.
