All this time we were steaming in a northerly and westerly direction. When we arrived at the southernmost end of New Guinea we stopped and lay to for a couple of days. I soon learned that we were waiting for a steamer and expected her any minute. During these days the _Wolf's_ hydroplane would go up to reconnoitre three times a day. It would travel fifty or sixty miles on clear days, and from a height of three thousand metres it had a vision of ninety miles, so the Germans claimed. One of the German sailors told me that in another day or so we should have plenty of beer--that they had picked up a wireless message stating that the Australian steamer _Matunga_ would soon arrive in Rabul with five hundred tons of coal and three hundred tons of foodstuffs, so many hundred cases of beer, etc., for the Government. Sure enough, on the morning of August 4th I was awakened by my orderly with the usual supply of cotton batting for our ears. Shortly thereafter there was a bang from one of the cannons and the _Matunga_ stopped. Lieut. Rose and the prize crew went on board and took charge. In about an hour the launch came back with the _Matunga's_ captain, Donaldson, and his officers and crew, also sixteen Australian soldiers who were en route to the Islands. Both steamers then proceeded north, arriving on August 10th at a place in northern New Guinea that we named Pirate Cove. [Illustration: SHOWING 4.7 "ORDINARY" PORTSIDE GUN FORWARD ON "WOLF." LIEUT. ROSE WITH BINOCULARS.] On the way to Pirate Cove Commander Nerger practised all kinds of naval manoeuvres with the _Wolf_ and the _Matunga_. At one time he would engage her in battle and finally after a fierce encounter, by superior manoeuvring he would destroy her. The next time the _Matunga_ would be an enemy's merchant vessel and the _Wolf_ would sneak up to her, suddenly dropping her ports, and make the capture. This manoeuvre was carried out quite realistically, the boarding crew supposedly meeting resistance and finally taking charge of her after a fight on deck, in which the boarding crew's bayonet drill would come in handy. At another time the _Matunga_ would be a German cruiser and Nerger would direct her attack against the enemy. At this time he was probably anticipating being made an Admiral on his return to Germany and was getting what practice he could.
