Here are the photos I mentioned. The quality is not great, but the second photograph includes what might be another D towards the top left of the photo. There are quite a number of vessels involved in the rescue. It may be possible to clean the pictures up a bit, but I'm not a Photoshop expert.....
If the material posted on-line about the sinking is accurate, these pictures will have been taken at about 14.30 on 25 September 1944 :
"As she steamed about 2,000 yd (1,800 m) out from the blockships, she was rocked at 14:15 by a tremendous underwater explosion under the engine room. ... She sank about 20 minutes after the explosion with a loss of some 58 officers and men."
