U-168 is not believed to have made any defensive maneuvers in the action, thus the Germans were sunk likely without realizing they were under attack until the torpedoes hit.
U-168 merasa tidak melakukan pertahanan apa pun dalam aksi tersebut, sehingga kapal Jerman tersebut tenggelam mungkin tanpa menyadari bahwa mereka diserang sampai torpedo menghantamnya.
