"I don't suppose he will mind that," Ned said. "I should think he must have had enough of India to last for his life."

"Mr. Latham," Dick said presently to the officer in command of the cavalry, "will you tell us your adventures? We know all about each other's doings."

So they sat and talked until ten o'clock, when Mr. Latham went round to see that the sentries were properly placed and alert. When he returned the door was shut, to keep out the damp air, and the whole party, rolling themselves in their cloaks, and using their saddles for pillows, laid up for the night. Dick was some time before he slept. His imagination was active; and when he at last dozed off, he was thinking what they had best do were they attacked by the enemy.

It was still dark when with a sudden start the sleeping party in the tomb awoke and leaped to their feet. For a moment they stood bewildered, for outside was heard on all sides the crack of volleys of musketry, wild yells and shouts, and the trampling of a large body of cavalry.

"Surprised!" exclaimed the colonel. "The sentries must have been asleep!"

There was a rush to the door, and the sight that met their eyes showed them the extent of the disaster. The moon was shining brightly, and by her light they could see that a large body of rebel cavalry had fallen upon the sleeping troopers, while the heavy musketry fire showed that a strong body of infantry were at work on the other side of the mosque. Lieutenant Latham rushed down the steps with his sword drawn, but fell back dead shot through the heart.

"Back, back!" shouted Colonel Warrener. "Let us sell our lives here!"

CHAPTER XXIII.

A DESPERATE DEFENSE.

In an instant the door was closed and bolted, and the four set to work to pile barrels and boxes against it. Not a word was spoken while this was going on. By the time they had finished the uproar without had changed its character; the firing had ceased, and the triumphant shouts of the mutineers showed that their victory was complete. Then came a loud thundering noise at the door.
