At 16.00 hours on 4 July, the ships arrived off Salinas and while the escorts went to Belém for refueling, the merchant ship waited for a harbour tug to be towed to a pier until her escorts returned. At 17.45 hours, the Pelotaslóide was hit on the starboard side by two torpedoes from U-590 and sank five miles north of Salinas, Brazil. The escorts immediately returned to the area, dropped depth charges on several sonar contacts and Jundiaí (CS 58) then picked up the survivors (five of them wounded).
