We saw a large steamer three miles away on the next day, but she, too, ignored our signals, probably thinking they were a ruse of an enemy submarine.

However, no other evidence appeared to confirm that an enemy submarine had been destroyed or damaged.

The next evening, she attempted to close an enemy submarine but lost contact with the target.

As a result the prospects of catching an enemy submarine on the surface were receding, and more emphasis was being placed on underwater engagements.

On the 10th, she depth-charged an enemy submarine, forced it to the surface, and damaged it heavily with 5 inch and 40-mm fire.
