This was the cruelest test of all. Paul, a victim to ever-increasing excitement, trembled with fever and rage.

"Come, Paul," said Bernard, "don't work yourself into such a state! We shall get there in time."

"In time for what?" he retorted. "To find her dead or wounded? Or not to find her at all? Oh, hang it, why can't our guns stop their damned row? What are they shelling, now that the enemy's no longer replying? Dead bodies and demolished houses! . . ."

"What about the rearguard covering the German retreat?"

"Well, aren't we here, the infantry? This is our job. All we have to do is to send out our sharpshooters and follow up with a good bayonet-charge. . . ."

At last the section set out again, reinforced by the remainder of the ninth company and under the command of the captain. A detachment of hussars galloped by, pricking towards the village to cut off the fugitives. The company swerved towards the château.

Opposite them, all was silent as the grave. Was it a trap? Was there not every reason to believe that enemy forces, strongly entrenched and barricaded as these were, would prepare to offer a last resistance? And yet there was nothing suspicious in the avenue of old oaks that led to the front court, not a sign of life to be seen or heard.

Paul and Bernard, still keeping ahead, with their fingers on the trigger of their rifles, searched the dim light of the underwood with a keen glance. Columns of smoke rose above the wall, which was now quite near, yawning with breach upon breach. As they approached, they heard moans, followed by the heart-rending sound of a death-rattle. It was the German wounded.

And suddenly the earth shook as though an inner upheaval had shattered its crust and from the other side of the wall came a tremendous explosion, or rather a series of explosions, like so many peals of thunder. The air was darkened with a cloud of sand and dust which sent forth all sorts of stones and rubbish. The enemy had blown up the château.

"That was meant for us, I expect," said Bernard. "We were to have been blown up at the same time. They were out in their calculations."
