"Yes, that must be avoided. What can be done?"

"I tell 'ee, sir. Leave three o' the wagons on the road, half a mile or so towards the village, where the road bends; I reckon Piet and Hans and me can keep any French patrol a-diddle-daddlen until the flag runs up. Then—do 'ee see, sir?—dragoons slip out of copse and trounce the Frenchmen, Piet and me and Hans draws the wagons across the road: and there be a barricade."

"A capital notion! I will leave that to you, then.—Ah! here is a man from the other direction. He may have news of the enemy."

A countryman, with his wife and family, had just driven up in a cart. From him Harry learnt that the French were sacking isolated farms on the road, and might be expected within the hour. Harry at once went back to the house, ran up the stairs, and again called for mademoiselle.

"May I go up to the roof and see if I can descry the enemy?" he asked.

"I will take you."

She led the way to the turret stair, and in a few moments Harry stood upon the roof, whence on fine days a clear prospect for many miles could have been obtained. The morning was somewhat overcast, and the haze limited his view. But in one quarter he seemed to see a blackness that could only arise from the smoke of burning houses. Between him and the cloud appeared the gables of a house larger than Madame de Vaudrey's chateau.

"That belongs to Monsieur de Polignac," said Adèle in reply to his question.

"The French will come to that first; that will gain a little time for us."

At that moment his eye caught the large barn-like building at the extremity of the Vaudrey estate, just beyond the ditch running into the canal. In a flash a new idea set his pulse leaping. Hitherto his only aim had been to delay or daunt the enemy until help could arrive from Breda or some nearer point. But the recollection of what he had seen when going round the estate on the previous evening suggested a daring scheme which made him tingle with excitement. Adèle looked at him in silent curiosity as he stood for a few moments pondering the situation. Then he turned suddenly to her.
