A sonar contact made earlier had been lost during the course changes required by the mine threat, but Underhill regained contact and guided PC-804 into a depth charge attack with no immediate results. A few minutes later, however, a sub was sighted on the surface in the area where PC-804 had attacked. Underhill set course to ram, but the sub dived and the command was changed to drop depth charges. A 13-charge pattern was laid, explosions brought up oil and debris, and PC-804 reported a kill.
