They watched the aide-de-camp deliver his message; but still Lord Lucan, who was in supreme command of the cavalry, made no move.

"What is he at?" cried Lord Raglan, testily. "He is very long about it."

"There is no time to lose, my lord," interposed the quartermaster-general, who had been intently watching the redoubts with his field-glasses. "I can see them bringing teams of horses into the redoubts. They evidently mean to carry off our guns."

The necessity for action was more than ever urgent and immediate.

"Lord Lucan must be made to move. Here, Airey! send him a peremptory order in writing."

The quartermaster-general produced pencil and paper from his sabretash, and wrote as follows:—

"Lord Raglan wishes the cavalry to advance rapidly to the front, and try to prevent the enemy from carrying away the guns. Immediate."

"That will do," said Lord Raglan. "Let your own aide-de-camp carry the order. He is a cavalry officer, and can explain, if required."

It was Nolan, the enthusiastic, ardent, devoted cavalry soldier, heart and soul, and overflowing now with joy at his mission, and the chances of distinction it offered the cavalry. A fine, fearless horseman, he galloped at a breakneck pace down the steep and rocky sides of the plateau, and quickly reached Lord Lucan's side.

The general read his orders, with lips compressed and lowering brow.
