The periscope of the submarine was next sighted on the quarter within 200 or 300 yards, and she came slowly past the ship still submerged and evidently examining the vessel closely through the periscope.

She passed within a few yards of the ship, then crossed the bow and came to the surface about 200 yards off and passed down the port side again close to.

Captain Campbell waited until every gun would bear before giving the signal for "action." The decoy ship's true character was then revealed; concealed gunports were thrown open; colours were hoisted, and a hot fire opened from all guns.

The submarine was hit at once and continued to be hit so rapidly that it was evidently impossible for her to submerge.

She sank in a very short time.
