Dandolo got as close as 7,000 meters before being attacked at 1830 hours by a destroyer which dropped four depth-charges causing some damage, notably to the periscope. The submarine escaped by going down to 120 meters. Some 120 depth-charges were heard until 2120 hours.
		13 Aug 1942	1530		As Dandolo was returning to base following the damage incurred the previous day, she was informed at 1530 hours of a damaged aircraft carrier (believed to be HMS Furious). She reverted course in the hope of intercepting it but, at 1645 hours, a new signal came cancelling the previous report and the submarine returned to base.
