This must have been the day on which the boy-king records in his journal,--
"11 Oct., 1551. Sir Thomas Arrondel had ashuerid my Lord that the Towre was sauf."
The "my Lord" here must have related to Somerset, which the King heard of in his conversation with Northumberland.
"being Fryday, the Duke was again apprehended, and committed to the Tower, on a charge of high treason."
"This morning none was at Westminster of the conspiratours. The first was the Duke, who came later than he was wont, of himself. After diner he was apprehendid."
"and so after dinner, he (the Duke) was apprehended; Sir _Thomas Palmer_, Sir _Thomas Arundel_, _Hamonde_, _Nudigates_, _John Seymour_, and _David Seymour_, were also made prisoners, the Lord _Gray_ being newly come out of the country was attached. Sir _Ralph Vane_, being sent for, fled. Upon the first message it was reported that he said that his Lord was not stout, and that if he could get home he cared not for any; but upon pursuit he was found in his servant's stable at Lambeth covered with straw. He was a man of fierce spirit, both sudden and bold, of no evil disposition, saving he thought scantiness of estate too great an evil. All these were the same night sent to the Tower, except Palmer, Arundel, and Vane, who were kept apart in the Court, well guarded in chambers apart. After these followed Sir _Thomas Holdcroft_, Sir _Miles Partridge_, Sir _Michael Stanhope_ and others. The day following the Dutchess of _Somerset_ was sent to the Tower, also with her were committed one _Crane_, and his wife, and her own chamber woman. _Crane_ confessed for the most part as _Palmer_ had done, and further added that the Lord _Paget's_ house was the place, where the nobility being invited to a banquet, should have lost their heads, and that the Earl of _Arundel_ was made acquainted with the practice by Sir _Michael Stanhope_. This _Crane_ was a man, who having consumed his own estate, had armed himself to any mischief. All these were sworn before the Council, and forthwith upon the information of _Crane_, the Earl of _Arundel_, and Lord _Paget_ were sent to the Tower."
"1551, xvj. day of October, was had to the Towre, Sir Thomas Arundell and Lady (with many others)."
