Here they found the young King ready to pursue his journey, and after paying him their respects, remounted to escort him. But before they had left the town, they quarrelled with Lord Richard Grey, charging him and the Marquis of Dorset (who was in London) with allegations similar to those they had preferred against Earl Rivers. The poor young King was greatly distressed at this position of affairs, and said he could say nothing as to the Marquis of Dorset, but as for the others he could answer for their conduct, as they had been continually with him. To this Buckingham replied, that they had carefully concealed their designs from him, which however were not the less certain. Lord Grey, with Sir Thomas Vaughan and Sir Richard Hawke, who were in attendance on the King, were at once arrested, and together with Earl Rivers, either on the same day or the next, were sent northward in custody of several persons, and finally incarcerated in Pontefract Castle, whose Governor was Sir Richard Ratcliffe, a partisan of Gloucester. The young King himself was re-conducted back to Northampton, practically as much a prisoner as his uncle and half-brother, and reserved ultimately for a similarly cruel fate. Thus the first act of this atrocious tragedy was completed. The news of this _coup-de-main_ having reached the Queen-Mother, she was greatly terrified, for she saw at a glance its full significance, and she immediately with her son the Duke of York, her other children, the Marquis of Dorset, and the rest of her family, took sanctuary at Westminster, as their only available refuge.
