As soon as Warwick ascertained that Edward had fled, he turned toward London, with nothing now to impede his progress. He entered London in triumph. Clarence joined him, and entered London in his train; for Clarence, though he had gone to England with the intention of making common cause with his brother, had not been able yet to decide positively whether it would, on the whole, be for his interest to do so, and had, accordingly, kept himself in some degree uncommitted, and now he turned at once again to Warwick's side. The queen--Elizabeth Woodville--with her mother Jacquetta, were residing at the Tower at this time, where they had King Henry in their keeping; for the Tower was an extended group of buildings, in which palace and prison were combined in one. As soon as the queen learned that Edward was defeated, and that Warwick and Clarence were coming in triumph to London, she took her mother and three of her daughters--Elizabeth, Mary, and Cecily--who were with her at that time, and also a lady attendant, and hurried down the Tower stairs to a barge which was always in waiting there. She embarked on board the barge, and ordered the men to row her up to Westminster. Westminster is at the upper end of London, as the Tower is at the lower. On arriving at Westminster, the whole party fled for refuge to a sanctuary there. This sanctuary was a portion of the sacred precincts of a church, from which a refugee could not be taken, according to the ideas of those times, without committing the dreadful crime of sacrilege. A part of the building remained standing for three hundred years after this time, as represented in the opposite engraving. It was a gloomy old edifice, and it must have been a cheerless residence for princesses and a queen. [Illustration: THE SANCTUARY.] In this sanctuary, the queen, away from her husband, and deprived of almost every comfort, gave birth to her first son. Some persons living near took compassion upon her forlorn and desolate condition, and rendered her such aid as was absolutely necessary, out of charity. The abbot of the monastery connected with the church sent in various conveniences, and a good woman named Mother Cobb, who lived near by, came in and acted as nurse for the mother and the child. The child was baptized in the sanctuary a few days after he was born. He was named Edward, after his father. Of course, the birth of this son of King Edward cut off Clarence and his son from the succession on the York side. This little Edward was now the heir, and, about thirteen years after this, as we shall see in the sequel, he became King of England.
