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. One
officer and one man were picked up. A signal was then made for
assistance and help arrived within a couple of hours. The decoy ship was
rapidly filling, but efforts were made to tow her into port, and with
the greatest difficulty, and entirely owing to the splendid manner in
which all hands stuck to the work, she was brought into Berehaven with
her stern under water thirty-six hours later and beached. The great
restraint shown by Captain Campbell, in withholding fire as the
submarine passed her in a submerged condition, and the truly wonderful
discipline and steadiness and ingenuity which baffled so close an
examination of the ship were the outstanding features of this great
exploit.

On April 22, 1917, a decoy ship known as "Q22," a small sailing vessel
with auxiliary power, armed with two 12-pounder guns, and commanded by
Lieutenant Irvine, R.N.R., while in a position about fifty miles south
of Kinsale Head, sighted a submarine on the surface which opened fire
immediately at a range of about 4,000 yards. The fire was accurate and
the decoy ship was hit frequently, two men being killed and four wounded
in a few minutes and the vessel considerably damaged. As further
concealment appeared useless the guns were then unmasked and the fire
returned with apparently good results, several hits being claimed. The
enemy's fire then fell off in accuracy and she increased the range, and
after about one and a half hours' fighting the light became too bad to
continue the action. It was thought that the submarine was sunk, but
there was no positive evidence of sinking.
