Four more vessels were consigned to watery graves. One of them, the Colombian sailing ship "Resolute", was stopped with "U-172"s 20mm gun and sunk with grenades. Another, "Santa Rita", had been abandoned by her crew, but was still afloat. A party from the U-boat boarded her and set scuttling charges. The master was found and taken prisoner. He was landed at Lorient when the submarine returned to base and was transferred, initially to Wilhelmshaven then the POW camp at Milag Nord near Bremen.
