He knows his own plans best.

You are to come with me at once into his presence." Robert was immediately in a great stir.

He straightened out, and, with his hands, brushed his own clothing, smoothed his hair, intending, with his usual desire for neatness, to make the best possible appearance before the French leader.
After breakfast Langlade took him to the great marquee in which Montcalm sat, as the morning was cool, and when their names had been taken in a young officer announced that they might enter, the officer, to Robert's great surprise, being none other than De Galissonniere, who showed equal amazement at meeting him there.

The Frenchman gave him a hearty grasp of the hand in English fashion, but they did not have time to say anything.
Robert, walking by the side of Langlade, entered the great tent with some trepidation, and beheld a swarthy man of middle years, in the uniform of a general of France, giving orders to two officers who stood respectfully at attention.

Neither of the officers was St.Luc, nor were they among those whom Robert had seen at Quebec.
