When a regular swept and buoyed channel was in use the enemy had little difficulty in deciding on the positions in which to lay mines by reason of the presence of the buoys. This fact constituted the principal disadvantage in the use of a buoyed channel, but in certain places where the traffic was heavy the procedure was inevitable, and it greatly simplified the work of the patrol craft and minesweepers; the only precautions possible lay in the use of alternative marked channels, and in the laying of defensive deep minefields outside the channel in which enemy submarines might compass their own destruction. As rapidly as our supply of mines admitted, this latter device was adopted in positions where the minefields could not constitute a danger to our own submarines. False buoyed channels with mined areas round them could also be laid in which to catch the submarine. Another device was that of altering the position of light vessels and buoys with the object of putting a submarine on to a shoal.
The situation with which our patrol and minesweeping craft had to deal having now been stated, it remains to speak of the magnificent manner in which they accomplished their task.
I regret very deeply that, in spite of a strong desire to undertake the task, I have neither the information nor the literary ability to do justice to the many deeds of individual gallantry, self-sacrifice and resource performed by the splendid officers and men who manned the small craft. No words of mine can adequately convey the intense admiration which I felt, and which I know was shared by the whole Navy, for the manner in which their arduous and perilous work was carried out. These fine seamen, though quite strange to the hazardous work which they were called upon to undertake, quickly accustomed themselves to their new duties, and the nation should ever be full of gratitude that it bred such a race of hardy, skilful and courageous men as those who took so great a part in defeating the greatest menace with which the Empire has ever been faced.
There are, however, just two cases in 1917, typical of many others, which I cannot forbear from mentioning. The first occurred off the East Coast of England.
On August 15 the armed fishing craft Nelson and Ethel and Millie were attacked by gunfire by a German submarine on the surface at a range of four to five miles.
The submarine first concentrated her fire on the Nelson, which immediately slipped her trawl and went to action stations. The third shot from the submarine pierced the trawler's bows, and, having established the range, the submarine poured a well-directed fire into the Nelson, under which she rapidly began to settle down.
The seventh shot struck the skipper, Thomas Crisp, D.S.C., R.N.R., taking off both his legs and partly disembowelling him.
In spite of the terrible nature of his injuries he retained consciousness and gave instructions to the mate, who was his son, to send a message by carrier pigeon to the senior officer of his base reporting that he was engaged with the enemy; he then bade him fight to the last.
The Nelson, armed with one small gun, replied to the enemy's fire until the heavy heel which she had assumed made it impossible to bring the gun to bear. As she was then on the point of sinking the mate decided to abandon her and take to the boat, and begged his father to give them leave to carry him. This, however, the old man sternly refused to do, and ordered his son to throw him overboard.
The nature of his wounds being such that he would have died if he had been moved, they deemed it best, after consultation, to leave him where he lay. Accordingly, yielding to his reiterated order to abandon the ship, they left this most gallant seaman lying in his blood, and embarked in the boat as the Nelson sank.
