The emperor was no tactician, but he knew the human heart. He knew that at any cost France must lead off with a victory, not only for the sake of the little man in the red trousers, but to impress watching Europe, and perhaps snatch an ally from among the hesitating powers. And the result was Saarbrück. The news of it filtered through to Colonel Gilbert, who was now quartered in the grey, picturesque Watrin barracks at Bastia, which jut out between the old harbour and the plain of Biguglia. The colonel did not believe half of it. It is always safe to subtract from good news. But he sat down at once and wrote to Denise Lange. He had not seen her, had not communicated with her, since he had asked her to marry him, and she had refused. He was old enough to be her father. He had asked her to marry him because she would not sell Perucca, and he wanted that estate; which was not the right motive, but it is the usual one with men who are past the foolishness of youth—that foolishness which is better than all the wisdom of the ages.

From having had nothing to do, Colonel Gilbert found himself thrown into a whirl of work, or what would have been a whirl with a man less calm and placid. Very much at ease, in white linen clothes, he sat in his room in the bastion, and transacted the affairs of his command with a leisurely good nature which showed his complete grasp of the situation.

With regard to Denise, this middle-aged, cynical Frenchman grasped the situation also. He was slowly and surely falling in love with her. And she herself had given him the first push down that facile descent when she had refused to be his wife.

“Mademoiselle,” he wrote, “to quarrel is, I suppose, in the air of Corsica, and when we parted at your gate some time ago, I am afraid I left you harbouring a feeling of resentment against me. At this time, and in the adverse days that I foresee must inevitably be in store for France, none can afford to part with friends who by any means can preserve them. In our respective positions, you and I must rise above small differences of opinion; and I place myself unreservedly at your service. I write to tell you that I have this morning good news from France. We have won a small victory at Saarbrück. So far, so good. But, in case of a reverse, there is only too much reason to fear that internal disturbances will arise in France, and consequently in this unfortunate island. It is, therefore, my duty to urge upon you the necessity of quitting Perucca without delay. If you will not consent to leave the island, come at all events into Bastia, where, at a few minutes' notice, I shall be able to place you in a position of safety. I trust I am not one who is given to exaggerating danger. Ask Mademoiselle Brun, who has known me since, as a young man, I had the privilege of serving under your father, a general who had the gift of drawing out from those about him such few soldierly qualities as they might possess.”

Denise received this letter by post the next morning, and, after reading it twice, handed it to Mademoiselle Brun, who was much too wise a woman to ask for an explanation of those parts of it which she did not comprehend. Indeed, she was manlike enough to pass on with an unimpaired understanding to the second part of the letter, whereas most women would have been so consumed by curiosity as to be unable to give more than half their mind to the colonel's further news.

“And—?” inquired mademoiselle—a Frenchwoman's way of asking a thousand questions in one. Mademoiselle Brun knew all the conversational tricks that serve to economize words.

“It is all based upon supposition,” said the erstwhile mathematical instructress of the school in the Rue du Cherche-Midi. “It will be time enough to arrive at a decision when the reverse comes. The Count de Vasselot or the Abbé Susini will, no doubt, warn us in time.”

“Ah!” said Mademoiselle Brun.

“But, if you like, I will write to the Count de Vasselot,” said Denise, in the voice of one making a concession.

Mademoiselle Brun thought deeply before replying. It is so easy to take a wrong turning at the cross-roads of life, and assuredly Denise stood at a carrefour now.
