Suddenly the girl broke loose and ran to the bow of the ship, which was pointed out to the ocean.
The warship had a long bowsprit, and the President's daughter made her way to the extreme limit of this.
"Come back!" roared the Chinese officer, and ran after her.
"Let me be, or I will leap overboard!" screamed the unhappy maiden, and then, as the officer came closer, she made a dive and disappeared beneath the bosom of the ocean.
By this time Oscar had caught up one of his pistols.
His aim was true and the Chinese officer pitched headlong into the water, mortally wounded.
The officer was an admiral in the Chinese navy, and a howl went up when the fatal shot was fired, and all eyes were turned in the direction of the Holland XI.
"Quick, we must rescue Martha Adams, no matter what the cost!" cried Oscar. "Will you stand by me, men?"
"We will!" came from Andy and the others.
"Then forward at full speed to where she went down. But take care that the Holland XI. does not strike the young lady."
