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. On April 30, 1917, a decoy ship--H.M.S. _Prize_--a small schooner with auxiliary power, armed with two 12-pounder guns and commanded by Lieutenant W.E. Sanders, R.N.R., a New Zealand officer, sighted, when in position Lat. 49.44 N., Long. 11.42 W., a submarine about two miles away on the port beam at 8.30 P.M. At 8.45 P.M. the submarine opened fire on the _Prize_ and the "abandon ship" party left in a small boat. The submarine gradually approached, continuing to pour in a heavy fire and making two hits on the _Prize_ which put the motor out of action, wrecked the wireless office, and caused much internal damage besides letting a great deal of water into the ship.
