The queen rejoined her husband, and she rendered him essential service in many ways. She had personal influence enough to raise both money and men for his armies, and so contributed very essentially to the strength of his party. At last she returned to the Continent again, and went to Paris, where she was still actively employed in promoting his cause. At one of the battles in which the king was defeated, the Parliamentary army seized his baggage, and found among his papers his correspondence with the queen. They very ungenerously ordered it to be published, as the letters seemed to show a vigorous determination on the part of the king not to yield in the contest without obtaining from the Parliament and their adherents full and ample concessions to his claims. [Sidenote: 1646.] [Sidenote: The royal cause declines.] [Sidenote: The Prince of Wales.] As time rolled on, the strength of the royal party gradually wasted away, while that of Parliament seemed to increase, until it became evident that the latter would, in the end, obtain the victory. The king retreated from place to place, followed by his foes, and growing weaker and more discouraged after every conflict. His son, the Prince of Wales, was then about fifteen years of age. He sent him to the western part of the island, with directions that, if affairs should still go against him, the boy should be taken in time out of the country, and join his mother in Paris. The danger grew more and more imminent, and they who had charge of the young prince sent him first to Scilly, and then to Jersey--islands in the Channel--whence he made his escape to Paris, and joined his mother. Fifteen years afterward he returned to London with great pomp and parade, and was placed upon the throne by universal acclamation. [Sidenote: Hopeless condition of the king.] At last the king himself, after being driven from one place of refuge to another, retreated to Oxford and intrenched himself there. Here he spent the winter of 1646 in extreme depression and distress. His friends deserted him; his resources were expended; his hopes were extinguished. He sent proposals of peace to the Parliament, and offered, himself, to come to London, if they would grant him a safe-conduct. In reply, they _forbade_ him to come. They would listen to no propositions, and would make no terms. The case, they saw, was in their own hands, and they determined on unconditional submission. They hemmed the king in on all sides at his retreat in Oxford, and reduced him to despair.
