The effective use of rapid-fire guns mounted on submarines in bona fide efforts to halt merchant steamers for purpose of visit and search is the important factor in the situation. A submarine not so equipped would find it difficult, if not impossible, to apply the rule of visit and search. Without the outside guns such a submarine would possess no other effective weapon than the torpedo. The submarine that carried no exterior armament could not compel obedience to its mandate for the merchant Captain to stop without firing a torpedo and thus risking the destruction of life with the sinking of the steamer, and a submarine with no outside armament might run the risk, as frequently contended by the German Admiralty, of bomb attack from the rails of the merchant steamer when going alongside of such a vessel.
A submarine like the U-38, which sank the Armenian, carrying one or more outside guns, capable of discharging various kinds of shell, from blank shots to shrapnel, represents an important evolution in the development of marine warfare. Such a craft has the equipment to enable her to visit and search a passing merchantman, and to provide for the safe removal of officers, crew or passengers from a challenged steamer, before the destruction of the vessel. It is only necessary for such a submarine to fire her torpedoes as a last resort for the destruction of the steamer. With her exterior guns a submarine like the U-38, upon meeting a merchant vessel, may fire one or more warning shots, as Captain Trickey of the Armenian says the U-38 did.[1] The raider, he said, fired two warning shots, and when he turned away from her and put on speed, the submarine's guns opened fire on him with shrapnel.
THE ANGLO-CALIFORNIAN
Like the Armenian, the British merchantman Anglo-Californian refused to lie-to when signaled by a German submarine on July 2. Her crew of ninety-five included fifty Americans and Canadians. A Queenstown dispatch of July 5 gave the following account of the action:
The Anglo-Californian left Montreal for the British Isles on June 24. The submarine was sighted at 8 o'clock last Sunday morning. Captain Parslow ordered full steam ahead and wireless calls for aid were sent out. The submarine on the surface proved to be a far speedier craft than the steamer and rapidly overhauled her, meanwhile deluging her with shells. One shot put the wireless apparatus on the Anglo-Californian out of action. Finding that he could not escape by running for it Captain Parslow devoted his attention to manœuvring his ship so as to prevent the submarine from using torpedoes effectively.
"Our Captain was a brave man," said one of the narrators. "He kept at his post on the bridge, coolly giving orders as the submarine circled around us vainly seeking to get a position from which it could give us a death blow with a torpedo. All the while the under-water boat continued to rain, shot and shell upon us, and at times was so close that she was able to employ rifle fire effectively.
"At last one shell blew the Captain off the bridge, killing him outright and terribly mutilating him. Just before that he had given orders to launch the boats, but this was very difficult under the shell fire. Several men were struck down while working at the davits. Ultimately four boats were got overboard and were rowed away until picked up."
The son of Captain Parslow, serving as second mate, was standing by his father's side when the Captain was killed. The son was knocked down by the violence of the explosion. Springing to his feet, he seized the wheel, and, as ably as his father had done, continued dodging the submarine. Another shell burst alongside him, shattering one of the spokes of the wheel, but young Parslow retained his post.
The wireless SOS calls that had been sent out at the first alarm had reached those able to give more than passive assistance, however, and British destroyers appeared. On their approach the submarine abandoned the attack and submerged. Young Parslow was still at the wheel when the destroyers came up.
