This was the voice of the British battleship Queen Mary, which, taking directions from the Glasgow's aviator, had fired the opening shot, telling the Germans that their approach had been discovered and that the passage of the Skagerak would be contested.

Immediately the German fleet slowed down; for the German admiral had no means of knowing the strength of the British fleet at that point. Hurried orders flashed back and forth. A few moments later three aeroplanes, which had been hanging low above the German fleet, dashed forward.

They had been ordered forth to ascertain the strength of the British.

In almost less time than it takes to tell it they were directly above the British fleet, which, so far, consisted only of five ships of war— besides the Glasgow, an armored cruiser, the Albert and Victoria, torpedo boats, being the Queen Mary and Indefatigable.

As the Germans approached in the air, a hydroplane ascended from each of the British ships and British aviators gave chase to the enemy. One, which had come too close, was brought down; but the other two returned safely to the shelter of the German fleet, where the British dare not follow them because of the presence of a superior force of the enemy.

But the German aviators had learned what they had been sent to learn. They had discovered the strength of the British. Again sharp orders were flashed from the German flagship.

The fleet came on faster.

Captain Raleigh, because of his seniority, had taken command of the small British squadron. He had drawn his ships up in a semicircle, heads pointed to the foe. As his aviators signalled that the Germans were again advancing, Captain Raleigh gave the command that had been long eagerly awaited by the men—a command which the commander of the Queen Mary had delayed giving until the last moment because he desired to give his men all the rest he could.

"Clear for action!" he thundered.

Jack glanced at his watch and as he did so eight bells struck.
