"Let us trust that nothing of the sort occurs," answered the officer. "Even as it is, I do not see that we can do anything to-night."

"What! is the attack on the city to be carried out to-night?" exclaimed George, incredulously.

"Those are the orders," replied his superior, simply.

George relapsed into silence, wondering even more at the ways of the Commander.

The sun was sinking, and they were now nearing their destination. Already in the distant haze they could see some of the spires of the city they were to take. Each man of that devoted little band realized that the critical moment was nearing, and each man braced himself for the effort that would be expected of him. The nightmare of it all was not yet passed, and the last stage, they knew, would be worse than its predecessors.

Six miles from the city a halt was made. The sun had already set, and the party that, at the start, had been a smart, compact, and fit body of troops, now trailed up to the halting-place in a scattered line, horses hardly able to put one foot before another, the men reeling and fainting with exhaustion in the saddle. It was a despairing sight to the officers in charge, with work to carry out that now seemed hopeless.

As each man rode up, the last flicker of discipline asserted itself, and they closed up their ranks in one long line, whilst the officer rode down inspecting them. After that the horses were off-saddled.

After a rest of two hours had been given, the men were called up and their Chief addressed them.

"It is," he said, "absolutely necessary to ride into Cairo to-night! Many men and horses are not fit to move, but the orders must be obeyed. I shall leave it to you yourselves to decide who can travel on. The officers will inspect their troops and assist in that decision."

After this, weary as they were, volunteers were not wanting, to a man they were all anxious; but on inspection it was found that one hundred and fifty only out of that nine hundred were fit to proceed further, and so it was decided that the gallant Major Watson should march in at the head of this infinitesimal force and demand the surrender of twenty thousand armed rebels.
