The camp of Boulogne contained at that time one hundred and fifty thousand infantry, with fifty thousand cavalry, so that its population was second only to Paris among the cities of France. It was divided into four sections, the right camp, the left camp, the camp of Wimereux, and the camp of Ambleteuse, the whole being about a mile in depth, and extending along the seashore for a length of about seven miles. On the land side it was open, but on the sea side it was fringed by powerful batteries containing mortars and cannon of a size never seen before. These batteries were placed along the edges of the high cliffs, and their lofty position increased their range, and enabled them to drop their missiles upon the decks of the English ships. It was a pretty sight to ride through the camp, for the men had been there for more than a year, and had done all that was possible to decorate and ornament their tents. Most of them had little gardens in front or around them, and the sun-burned fellows might be seen as we passed kneeling in their shirt-sleeves with their spuds and their watering-cans in the midst of their flower-beds. Others sat in the sunshine at the openings of the tents tying up their queues, pipe-claying their belts, and polishing their arms, hardly bestowing a glance upon us as we passed, for patrols of cavalry were coming and going in every direction. The endless lines were formed into streets, with their names printed up upon boards. Thus we had passed through the Rue d'Arcola, the Rue de Kleber, the Rue d'Egypte, and the Rue d'Artillerie Volante, before we found ourselves in the great central square in which the headquarters of the army were situated. The Emperor at this time used to sleep at a village called Pont de Briques, some four miles inland, but his days were spent at the camp, and his continual councils of war were held there. Here also were his ministers, and the generals of the army corps which were scattered up and down the coast came thither to make their reports and to receive their orders. For these consultations a plain wooden house had been constructed containing one very large room and three small ones. The pavilion which we had observed from the Downs served as an ante-chamber to the house, in which those who sought audience with the Emperor might assemble. It was at the door of this, where a strong guard of grenadiers announced Napoleon's presence, that my guardian sprang down from his horse and signed to me to follow his example. An officer of the guard took our names and returned to us accompanied by General Duroc, a thin, hard, dry man of forty, with a formal manner and a suspicious eye. 'Is this Monsieur Louis de Laval?' he asked, with a stiff smile. I bowed. 'The Emperor is very anxious to see you. You are no longer needed, Lieutenant.' 'I am personally responsible for bringing him safely, General.'
