Heavy armament would have availed the Lusitania nothing, even if the vessel had been so equipped, declared Captain Lake. Even if the Cunarder had been bristling with guns from bow to stern, she could have done no damage to the under-water craft that attacked her. She was doomed when the submarine approached her. The submarine with its periscope three feet under water could not have been seen fifty feet distant from the liner’s side, and the chances were she was 1,000 yards distant. No shot from the vessel could have located her, though aimed by trained officers. ATTACK ON LINER DESCRIBED The scenes on both the vessel and the little submarine may be pictured from a theoretical description given by Captain Lake as follows: “The great ship, knowing the lurking danger, is traveling at her best speed limit, changing the course from time to time in a zigzag manner. Waiting beneath the surface of the calm sea a big submarine, now said to be capable of discharging a torpedo at a distance of five miles, rolls idly in the underground swell. Her crew is sleeping or talking in the semi-fetid atmosphere that the compressed air tanks relieve from time to time. An officer sits with his eye glued to a periscope, which constantly revolves that he may discern the rising smoke of an approaching vessel. “On the deck of the Lusitania passengers are lolling in steamer chairs or leaning over the rails. They covertly fear attack, yet the horizon shows no sign of the impending calamity. “Suddenly the submarine commander focuses his periscope upon a faint and hazy line on the horizon. Closely he watches it move. An electric signal is given and the submarine crew is in place. Another and the boat swings silently and slowly on its course diagonal to that of the approaching vessel. The electric engines turn without noise. “The vessels near each other. An order is transmitted from the conning tower to the forward compartment of the submarine. The outside ports of two bow torpedo tubes are closed; compressed air drives out all water. Two inside ports are carefully opened and two one-ton torpedoes are lifted by means of chain tackle and swung carefully into the tubes. The inside ports are closed and the outside ports again opened. The air chamber between the torpedo and the breaches is filled with air compressed to nearly 1,200 pounds to the square inch--nearly the force of exploding dynamite. “Both vessels are closing together at right angles. On the bigger one all is gayety and hope of early and safe arrival at port. On the submarine all are alert. The bow is carefully trained toward a direct line over which the ship must travel. The speed and distance are carefully gauged by trained officers.
