In November 1942 HMS Lotus was operating in support of Operation Torch. On 13 November she and HMS Poppy made an ASDIC contact on a submerged U-boat off the coast of Algeria. They attacked with depth charges and were rewarded with sounds of the vessel breaking up underwater. Lt. HJ Hall, the captain of Lotus, described this sound in his report with the Greek expression pompholoogopaphlasmasin, quoting "an onomatopeic line from Aristophanes". When the Admiralty received this they were taken with it, and had the report circulated with the appropriate explanation.

- "Or when fleeing the storm, we went
- Down to the depths and our choral song
- Wildly raised to a loud and long
- Bubble-bursting accompaniment"
Postwar analysis credited Lotus and Poppy with the destruction of U-605. However, this assessment was later changed, as further research determined in 1987 that the attack on 13 November had been directed at U-77 (which survived, with little damage) while U-605 had been destroyed on a different occasion the following day.
