Early in June the Wolf, while at anchor under the lee of an island in the Pacific, sighted the British steamship Wairuna, bound from Auckland, N. Z., to San Francisco with coal, Kauri gum, pelts, and copra. The Wolf sent over the seaplane which, flying low, dropped a canvas bag on the Wairuna's deck, containing the message, "Stop immediately; take orders from German cruiser. Do not use your wireless or I will bomb you." The Wairuna eased down, but did not stop until the seaplane dropped a bomb just ahead of her. By this time the Wolf had weighed anchor and proceeded to head off the Wairuna. A prize crew was put on board with orders to bring the ship under the lee of the island and anchor. All the officers, except the master, were sent on board the Wolf. The following day possibly a thousand tons of cargo were transferred. CAPTURE OF THE MATUNGA While the two vessels were anchored, the chief officer and second engineer of the Turritella let themselves over the side of the Wolf with the intention of swimming ashore. Later, the Wairuna was taken out and sunk by gunfire, the bombs which had been placed on board having failed to accomplish their purpose. The next captures were the American vessels, Winslow, Beluga, and Encore, which were either burned or sunk. For nearly a week following this the Wolf hove to, sending the seaplane up several times each day for scouting purposes. Apparently she had picked up some information by her wireless apparatus and was on the lookout for a vessel. On the third day the Wolfchen went up three times, and, on returning from its last flight, dropped lights. Early the next morning none of the prisoners was allowed on deck. A gun was fired by the Wolf, and it was afterward found that it was to stop the British steamer Matunga, with general cargo and passengers, including a number of military officers and men.
