A photograph taken a day or two after the attack. The hole made by the torpedo can be seen directly below "B" turret (the second gun turret from the front). This photo was most likely to have been taken by a member of the crew of HMS Petard, the destroyer that escorted Arethusa on the journey back to Alexandria.
If you compare this photo to the one on the home page you will see how low in the water the bows of ship are.
This photo is available from the National Maritime Museum, quote negative number P39798
