Two torpedoes passed close to the _DeKalb_ from port to starboard, one about 30 yards ahead of the ship and the other under her stern, as the ship was turning to the northward. Captain Gherardi stated that at 10:25 the wake of a torpedo was sighted directly across the _DeKalb's_ bow. A second torpedo wake was reported ten minutes later by the after lookouts. The torpedoes fired at the _Havana_ passed from starboard to port about 40 yards ahead of the ship, leaving a distinct wake which was visible for 400 or 500 yards. The submarine sighted by the _Seattle_ was seen by the _Wilkes_ and passed under that ship, Lieutenant Van Metre reported, stating that the oscillator gave unmistakable evidence of the presence of a submarine. The radio operator at the receiver reported, "Submarine very close to us." As the U-boat passed, it was followed by the _Wilkes_, which ran down between the columns, chasing the enemy. The _Birmingham_, leading the second group, encountered two submarines, the first about 11:50 a. m., June 26, in latitude 47° 01´ N. longitude 06° 28´ W., about a hundred miles off the coast of France, and the second two hours later. The _Wadsworth_ investigated the wake of the first without further discovery. The _Cummings_ sighted the bow wave of the second at a distance of 1,500 yards, and headed for it at a speed of 25 knots. The gun pointers at the forward gun saw the periscope time and again, but as the ship was zigzagging, it disappeared each time before they could fire at it. The _Cummings_ passed about 25 yards ahead of a mass of bubbles which were coming up from the wake and let go a depth-charge just ahead. Several pieces of timber, quantities of oil, bubbles and debris came to the surface. Nothing more was seen of the submarine. The attacks on the second group occurred about 800 miles to the eastward of where the attacks had been made on the first group. The voyage of the third group, Admiral Gleaves reported, was uneventful; but the _Kanawha_, with the fourth group, on June 28th, fired on what was believed to be a submarine. The _Kanawha's_ commander saw the object; and a minute or two later the port after gun's crew reported sighting a submarine, and opened fire. The lookouts said they saw the U-boat under the water's surface, about where the shots were landing. Lieutenant (junior grade) Lee C. Carey, in charge of the firing, reported that he saw the submarine fire two torpedoes in the direction of the convoy, which sheered off when the alarm was sounded. "All the officers and men aft had observed the torpedoes traveling through the water and cheered loudly when they saw a torpedo miss a transport," reported the _Kanawha's_ commander. When he was in Paris Admiral Gleaves was shown a confidential bulletin of information issued by the French General Staff, dated July 6, which contained the following:
