"U-123" sailed to the West African coast. She sank the Spanish-registered motor ship on 8 April 1943 west of Conakry, French Guinea. As per maritime rules, the neutral ship had the Spanish flag painted in both sides. Commander Horst von Schroeter ordered the shooting of 3 torpedoes and she sunk in less than a minute. The submarine surfaced, the commander confirmed that it just sunk a neutral ship, said ""What ship?"" and left without giving any assistance to the 40 survivors (five went down with the ship).
