Early that same morning the "Minotaur" signalled to the "Maunganui": "I am ordered on another service; wish you the very best of success when you land in France. Give the Germans a good shake-up. It has been a great pleasure to escort such a well-disciplined force and convoy. Good-bye." The Triumph of Australia. The flagship's place ahead was now held by the "Melbourne," with the "Ibuki" to starboard and the "Sydney" to port. With the news of the Valparaiso battle and the departure of the "Minotaur" came word that the Cocos Islands would be passed during the night, and special precautions were ordered to be taken in regard to lights. The usual sharp look-out was kept, but the hours of darkness slipped by without incident. But at 6.30 a.m. the "Melbourne" turned to port and spoke for a few minutes to her sister ship. By this time all the transports were aware of the wireless messages from the Cocos Islands signalling "S.O.S.," "Strange warship approaching." The Australian transport "Karoo" and the New Zealand transport "Arawa" picked up the following: "PNX DE WSP DE PNX NE DE NGI PFB DEO," also, "S.O.S.--Strange warship at entrance. Ignores our remarks--S.O.S., S.O.S.," then a long message, apparently in Dutch. These mixed-up messages, obviously mutilated and jammed by the hostile Telefunken, provided knotty problems for those whose duty it was to fathom the mysteries of code and cypher. [Illustration: THE LAST OF THE "EMDEN." While the "Sydney" dealt with the "Emden," the "Ibuki" and "Melbourne" lay on the threatened quarter of the convoy. The action took place out of the sight and sound of the troops on the transports, which were over seventy miles away from the Cocos Group.] The captain of the "Melbourne," being in charge of the convoy, could not go to the Cocos Islands, sixty miles away, so ordered the "Sydney" on this service. By 7 a.m. the cruiser had worked up to her speed and was rapidly lost to sight. The "Melbourne" came down to the "Sydney's" place on the threatened flank, and then the attention of the whole convoy was rivetted on the Japanese cruiser coming across from starboard around the head of the convoy. As she forged ahead through the heavy swell a great white wave streamed over her bows, being made more conspicuous by her pitch black hull and the three black funnels belching enormous columns of dense black smoke. Tearing through the indigo Indian Ocean, with her great battle flags streaming blood-red in the breeze, she became the very personification of energy and power. With the two cruisers lying handy on the threatened flank, the troops waited anxiously for news. All realized that just across the horizon a life and death struggle was taking place. No sound of battle could be heard but the spluttering of the wireless, from which it was learned at 9.30 that the enemy had been brought to action.
