Atropo (AT, N.51)31 Aug 19430805Taranto31 Aug 19431220Taranto20Exercises with the steam trawler Claretta. The submarine had received an order to lay an experimental minefield (36 mines) but it is not clear if the order was executed.
  31 Aug 19430900+40° 24'N, 17° 12'EAtropo had orders to lay an experimental minefield with 36 mines of the P.1939 type. The position was starting from a point 186° - San Vito Light - 1,600 metres to 150° - San Vito Light - 4.600 metres. This was to be done submerged, at a speed of 4.5 knots for the first 10 mines and at 4 knots for the remainder. This would have been the first mines laid by Italian submarines since the negative experiences of October 1940. It is perhaps noteworthy to remark that the submarine was required to indicate her position by the regular discharge of air bubbles and that two motorboats and a launch with divers were to be put on standby by MARISUB Taranto in case of accident.

It is not clear if the minefield was actually laid, but the submarine is known to have been at sea for exercises during this morning, escorted by steam trawler Claretta.
