Richard was taken prisoner.

She then hastened to town, intending to seek him wherever he might be;
but on her arrival she learned from him that he would shortly be
brought to London, and he appointed a place near Charing Cross where
she should meet him. Their interview lasted only a few hours; after
which he was conveyed to Whitehall, and was closely confined there for
ten weeks, expecting daily to be put to death. The manner in which she
went secretly to his prison at four o'clock every morning, and her
unwearied zeal to alleviate his sufferings, afford a beautiful example
of female devotion; and it was owing to her exertions alone that he
was ultimately released on bail.

Illness induced Sir Richard to go to Bath, in August 1652, the greater
part of the winter of which year they passed at Benford, in
Hertfordshire; but having occasion to wait on the Earl of Strafford,
in Yorkshire, his Lordship offered him a house in Tankersley Park,
which he accepted. His family removed thither in March 1652, and
during his residence there he amused himself in literary pursuits, and
translated Luis de Camoens. The death of their favourite daughter
Anne, on the 23rd of July 1654, at the age of between nine and ten,
made them quit Tankersley, and they proceeded to Homerton, in
Huntingdonshire, the seat of Sir Richard Fanshawe's sister, Lady
Bedell, where they resided six months; when he being sent for to
London, and forbidden to go beyond five miles of it, his wife and
children removed to the metropolis. Excepting a visit to Frog Pool, in
Kent, the residence of Sir Philip Warwick, they remained in London
until July 1656, during which time Lady Fanshawe had two children, and
her husband suffered severely from illness.
