In the running battle which followed, "Bartolomeo Colleoni" was hard hit by "Sydney" and after a shell hit the boilers at 09:23 she stopped dead in the water. She fought on but was unable to manoeuvre or use the main battery; despite the fire from her guns, she was sunk by three torpedoes launched from "Ilex" and "Hyperion" at 09:59. "Sydney" continued to fire against "Bande Nere". She was hit in the funnel by a single Italian shell, but managed to hit "Bande Nere" at least twice, killing eight in the bow and the hangar. Later, "Sydney" disengaged because she was short of ammunition and "Giovanni delle Bande Nere" returned to Benghazi, shadowed by the battleship HMS "Warspite" and a screen of destroyers. 555 survivors of "Bartolomeo Colleoni" were rescued; 121 died. The British destroyers were bombed by Italian aircraft in the aftermath, resulting in damage to HMS "Havock", whose nº 2 boiler was flooded. A floatplane from "Warspite", which was searching for "Bande Nere", ditched in the sea and was lost near Tobruk. The crew was captured by the Italians. Allied convoy AN.2 was ordered to sail back to Port Said and remain there until it was eventually known that "Bande Nere" had reached Benghazi.
