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).
