After he had been there for three months he was one day led out and, with three other midshipmen, taken down to a prison in the town. He had no doubt that prisoners of more importance had arrived, and that he and the others had been moved to make way for them. A month later they were again taken out, and, having been joined by a hundred other prisoners under a strong guard, were marched out of the town. There were five officers among them, and the rest were seamen. All were glad of the change, though it was not likely to be for the better. Will was sorry, inasmuch as at Toulon he could always hope that if he escaped from prison he would be able to get hold of a boat and row out to the blockading squadron. Inland he felt that escape would be vastly more difficult. Even if he got out of prison he knew but little French, and therefore could hardly hope to make his way across country. They trudged along day after day, each according to his fancy, some sullen and morose, others making the best of matters and trying to establish some speaking acquaintance with their guards, who evidently regarded the march as a sort of holiday after the dull routine of life in a garrison town. Will, who had during his imprisonment at Toulon studied to improve his French to the best of his ability by the aid of some books he had obtained and by chatting with his jailer, worked his hardest to add to his knowledge of the language, and as the French soldiers were quite glad to beguile the time away by talking with their captives, he succeeded at the end of the journey, which lasted nearly a month, in being able to chat with a certain amount of fluency. Verdun was one of the four places in which British prisoners were confined. At that time France had fifteen thousand prisoners, England forty thousand. By an agreement between the governments these were held captive in certain prisons, so that they could, when occasion offered, be exchanged; but owing to the vastly greater number of English prisoners the operation went on very slowly. The health of the prison was bad, the large number confined in the narrow space, and the lack of sanitary arrangements, causing a vast amount of fever to prevail.
