2.Smeraldo (SD)15 Sep 19410625Augusta26 Sep 1941Date???Sunk (with all hands)Sailed for patrol in zone K2 (between 36°53'N and 36°57'N, and between 11°12'E and Tunisian coast, off Kelibia, Cape Bon) [next to Alagi in zone K.1] and on 21st September also ordered to K.3. Disappeared without a trace. Was to have left her patrol on 25th September and reach home on the 27th. Probably mined (five officers and forty ratings killed).
  26 Sep 1941Date approx.
(0) Sicilian Channel?
Smeraldo disappeared without a trace. T.V. Bartolomeo La Penna, four officers and forty ratings perished.

She was probably mined, possibly on minefield 5 AN bis, consisting of 216 ELIA mines laid on the night of 8/9th August 1940 by the destroyers of the X^ Squadriglia (Maestrale, Grecale, Libeccio and Scirocco) from 36°53' N, 11°16.4' E to 36°56' N, 11°30.2' E. The eastern edge of Smeraldo's patrol area was only 3.5 miles west of this minefield and she could easily have strayed in it through an error in navigation.

The minelayer Scilla, escorted by the torpedo-boats Alcione and Sagittario, laid minefield 5 AN the same night but it was further east.

28 entries. 26 total patrol entries (2 marked as war patrols) and 4 events.
