"Steady on there!" shouted the Commander. "What the deuce are you up to?"

Von Hauptwald had broken into a run across the quarter-deck. With a bound he cleared the stanchion-rails, and plunged head foremost into the sea.

He had realized that to remain on the cruiser meant arrest and ultimate death as a dangerous spy. Better by far to be drowned without further delay than to experience all the horrors of lying under sentence of death.

He had acted spontaneously, yet there was method in his madness. By running across to the other side of the ship there was little chance of the boats being able to pick him up ere he sank for the last time. Not until he rose to the surface did he realize his difficulty. He was a strong swimmer, and the natural instinct to strike out overpowered his determination to sink.

There was a rush of officers and men to the ship's side to see what was taking place. With two exceptions, they thought that the supposed seaman had suddenly lost his reason.

Two seamen, one a brawny specimen, the other a red-haired middle-weight, dived after the would-be suicide. Others were on the point of following when the Commander restrained them.

"Away sea-boat!" was the order.

The Oxford was now forging slowly through the water. During the rescue of the Tehuantepec Girl's people, she had drifted rather too close to the burning ship to be safe, should an explosion occur. Already von Hauptwald was fifty yards astern, with the two seamen swimming towards him with powerful strokes.

His efforts to drown were a failure. He simply couldn't keep his head under. His attempts to swallow quantities of salt water only increased the instinctive motion of the limbs to keep himself afloat. Bitterly he regretted that he had not picked up some heavy metal object during his career across the cruiser's quarterdeck.

The approach of his would-be rescuers made him realize the necessity of self-destruction. At the encouraging shout of "Cheer up, old mate, you're safe!" spluttered by the leading seaman, he dived, pressing his chest with both hands in the hope that he would be able to expel the air from his lungs.
