6162. Not for circulation. It appears that U-152 was in about 44.00 North 39.00 West September 30th and is not likely therefore to reachlongitude Nantucket before about October 12th. Evidently U-139 was submarine which sunk two ships by gunfire in about 45.30 North 11.00 West October 1st and is therefore not proceeding America at present. Her commanding officer Arnauld de la Periere is firm believer in attack by gunfire. 161503 6162
