Harry, who was rather bewildered with the din and turmoil of the fight, did as the rest, and followed two or three of the men into one of the houses, whose door had been broken open. They were assailed as they entered by a fire of musketry from the Parliament men within. Those in front fell, and Harry was knocked down by the butt of a pike. When he recovered he found himself in a boat drifting down the stream, a prisoner of the Roundheads. For a long time Harry could hear the sounds of the guns and cannon at Brentford, and looking round at the quiet villages which they passed on the banks, could scarce believe that he had been engaged in a battle and was now a prisoner. But little was said to him. The men were smarting under their defeat and indulged in the bitterest language at the treachery with which, after negotiations had been agreed upon, the advance of the Royalists had been made. They speedily discovered the youth of their captive, and, after telling him brutally that he would probably be hung when he got to London, they paid no further attention to him. The boat was heavily laden, and rowed by two oars, and the journey down was a long one, for the tide met them when at the village of Hammersmith, and they were forced to remain tied up to a tree by the bank until it turned again. This it did not do until far in the night, and the morning was just breaking when they reached London. It was perhaps well for Harry that they arrived in the dark, for in the excited state of the temper of the citizens, and their anger at the treachery which had been practiced, it might have fared but badly with him. He was marched along the Strand to the city, and was consigned to a lock-up in Finsbury, until it could be settled what should be done to him. In fact, the next day his career was nearly being terminated, for John Lilburn, a captain of the Train Bands, who had been an apprentice and imprisoned for contumacy, had been captured at Brentford, and after being tried for his life, was sentenced to death as a rebel. Essex, however, sent in word to the Royalist camp that for every one of the Parliament officers put to death, he would hang three Royalist prisoners. This threat had its effect, and Harry remained in ignorance of the danger which had threatened him. The greatest inconvenience which befell him was that he was obliged to listen to all sorts of long harangues upon the part of the Puritan soldiers who were his jailers. These treated him as a misguided lad, and did their best to convert him from the evil of his ways. At last Harry lost his temper, and said that if they wanted to hang him, they might; but that he would rather put up with that than the long sermons which they were in the habit of delivering to him. Indignant at this rejection of their good offices, they left him to himself, and days passed without his receiving any visit save that of the soldier who brought his meals. CHAPTER IV.
