After the death of Colonel Wall with more and more Parliamentary soldiers streaming into the breaches, the Royalist resistance at the walls collapsed.

Very pretty and plentiful entertainment, could not get away till nine at night, and so home. My coach cost me 7s.
Note 1. Colonel Williams-"Cromwell that was"-appears to have been Henry Cromwell, grandson of Sir Oliver Cromwell, and first cousin, once removed, to the Protector. He was seated at Bodsey House, in the parish of Ramsey, which had been his father's residence, and held the commission of a colonel. He served in several Parliaments for Huntingdon [Map]shire, voting, in 1660, for the restoration of the monarchy; and as he knew the name of Cromwell would not be grateful to the Court, he disused it, and assumed that of Williams, which had belonged to his ancestors; and he is so styled in a list of knights of the proposed Order of the Royal Oak. He died at Huntingdon [Map], 3rd August, 1673. (Abridged from Noble's "Memoirs of the Cromwells", vol. i., p. 70.) B.
Note 2. The date 3rd August, 1673 quoted in Note 1 appears to be incorrect. He died on 23 Mar 1674.
