The drama beneath them was rapidly approaching its climax.  The Halfa Corps was well up, and a ring of smoke and flame surrounded the clump of kneeling Dervishes, who answered it as best they could.  Many of them were already down, but the rest loaded and fired with the unflinching courage which has always made them worthy antagonists.  A dozen khaki-dressed figures upon the sand showed that it was no bloodless victory for the Egyptians.  But now there was a stirring bugle call from the Sarras men, and another answered it from the Halfa Corps.  Their camels were down also, and the men had formed up into a single, long, curved line.  One last volley, and they were charging inwards with the wild inspiriting yell which the blacks had brought with them from their central African wilds.  For a minute there was a mad vortex of rushing figures, rifle butts rising and falling, spear-heads gleaming and darting among the rolling dust cloud.  Then the bugle rang out once more, the Egyptians fell back and formed up with the quick precision of highly disciplined troops, and there in the centre, each upon his sheepskin, lay the gallant barbarian and his raiders.  The nineteenth century had been revenged upon the seventh.

The three women had stared horror-stricken and yet fascinated at the stirring scene before them.  Now Sadie and her aunt were sobbing together.  The Colonel had turned to them with some cheering words when his eyes fell upon the face of Mrs. Belmont.  It was as white and set as if it were carved from ivory, and her large grey eyes were fixed as if she were in a trance.

“Good Heavens, Mrs. Belmont, what is the matter?” he cried.

For answer she pointed out over the desert.  Far away, miles on the other side of the scene of the fight, a small body of men were riding towards them.

“By Jove, yes; there’s some one there.  Who can it be?”

They were all straining their eyes, but the distance was so great that they could only be sure that they were camel-men and about a dozen in number.

“It’s those devils who were left behind in the palm grove,” said Cochrane.  “There’s no one else it can be.  One consolation, they can’t get away again.  They’ve walked right into the lion’s mouth.”

But Mrs. Belmont was still gazing with the same fixed intensity, and the same ivory face.  Now, with a wild shriek of joy, she threw her two hands into the air.  “It’s they!” she screamed.  “They are saved!  It’s they, Colonel, it’s they!  Oh, Miss Adams, Miss Adams, it is they!” She capered about on the top of the hill with wild eyes like an excited child.
