“Gentlemen,” said he, “I have been asked to call for a volunteer from among you for a service which involves the greatest possible danger. I will not disguise from you that the matter is serious in the last degree, and that Marshal Lannes has chosen a cavalry officer because he can be better spared than an officer of infantry or of engineers. Married men are not eligible. Of the others, who will volunteer?”

I need not say that all the unmarried officers stepped to the front. The colonel looked round in some embarrassment.

I could see his dilemma. It was the best man who should go, and yet it was the best man whom he could least spare.

“Sir,” said I, “may I be permitted to make a suggestion?”

He looked at me with a hard eye. He had not forgotten my observations at supper. “Speak!” said he.

“I would point out, sir,” said I, “that this mission is mine both by right and by convenience.”

“Why so, Captain Gerard?”

“By right because I am the senior captain. By convenience because I shall not be missed in the regiments since the men have not yet learned to know me.”

The colonel's features relaxed.

“There is certainly truth in what you say, Captain Gerard,” said he. “I think that you are indeed best fitted to go upon this mission. If you will come with me I will give you your instructions.”
