After capturing the schooner from the mutineers, a prisoner was found on board, who proved to be a British secret service agent. The boys released him, and then, with Lord Hastings, who had come to Africa in his yacht, succeeded in striking such a blow at the Triple Alliance that Italy refused to throw her support to German arms in spite of the strongest pressure the Kaiser could bring to bear.
So valuable was the service the boys rendered in this matter, that when they expressed their intentions of joining the British navy, Lord Hastings, who had taken an immense liking to them, secured them commissions as midshipmen. Later they were assigned to duty on his yacht, the Sylph, which, in the meantime, had been converted into a scout cruiser.
The lads had already played an important part in the war. Through them, a plot to destroy the whole British fleet had been frustrated and the English had been enabled to deliver a smashing blow to the German fleet at Heligoland.
In Lord Hastings the boys had found an excellent friend. Although apparently but a commander of a small scout cruiser—unknown to but a very few—he was one of the most trusted of British secret agents. He was a distant relative of the English monarch and, as the boys had already learned, had more power in naval affairs than his officers and associates surmised. This fact had been proved more than once, when he had given commands to men apparently much higher in rank.
Following the brilliant victory of the British fleet off Heligoland, in which a number of the Kaiser's most powerful sea fighters had been, sent to the bottom, the Sylph had returned to London for repairs. Here Frank and Jack had been personally presented to King George, who had thanked them for their bravery and loyalty and raised them to the rank of Fourth Lieutenant.
Lord Hastings had been ill, but his illness had been of short duration; and so it was not long before the two lads once more found themselves pacing the deck of the Sylph, going they knew not where; nor did they care much, so long as it took them where there was fighting to be done.
It was on the very day that the Sylph lifted anchor for her second cruise, that London heard of the prowess of the German cruiser Emden, a swift raider which later caused so much damage to British shipping as to gain the name "Terror of the Sea." The news received on the day in question told of the sinking of an English liner by this powerful enemy.
When Frank and Jack sought to learn the destination of the Sylph from Lord Hastings, he had put them off with a laugh.
"You'll know soon enough," he said with a wave of his hand.
"Are we likely to see action soon?" asked Jack.
