and his fate for some time hung in the balance. He succeeded in escaping from the Tower of London, wading the moat once he had got over the walls, only to be betrayed by a Thames waterman, who had been engaged to row him from a hiding place at the Temple to one in Lambeth. He was again captured and was condemned to death by parliament, on 8 March 1649, and beheaded together with the Duke of Hamilton and the Earl of Holland. One of Lord Capell's last requests was for his heart to be buried with the body of King Charles I, and after his execution, Capell's heart was preserved in a silver box. The silver box was kept in the custody of the Bishop of Winchester, and was later presented, by the Bishop, to King Charles II. In 1703, a heart in a silver box was found at Hadham Hall, suggesting that the King sent the heart to Capell's son. It was later taken to Cassiobury, but since the dissolution and sale of the Cassiobury estate, the whereabouts of Capell's heart are now unknown. A memorial stone to Lord Capell was erected at St Cecelia's Church in Little Hadham, Hertfordshire. Works Capell wrote Daily Observations or Meditations: Divine, Morall, published with some of his letters in 1654, and reprinted, with a short life of the author, under the title Excellent Contemplations, in 1683. Marriage and children On 28 November 1627, Capell married Elizabeth Morrison, daughter and sole heiress of Sir Charles Morrison of Cassiobury, Hertfordshire, and Mary Hicks, who brought the Cassiobury estate, including Cassiobury House, into his family, making him one of the richest men in England. His lands were scattered across ten counties and brought him a reputed annual income of £7,000. By his wife, he had four daughters and five sons, including: Anne Capell, wife of John Strangways, MP. Mary Capell (1630–1715), wife of Henry Somerset, 1st Duke of Beaufort. Arthur Capell, 1st Earl of Essex (1631–1683), eldest son and heir, created Earl of Essex at the Restoration. When the Earl, facing charges of treason, committed suicide in 1683, King Charles II remarked that he should have known his life would be spared, for "his father died for mine". Elizabeth Capell (1633–1678), wife of Charles Dormer, 2nd Earl of Carnarvon. Henry Capell, 1st Baron Capell of Tewkesbury (1638–1696), a politician and founder of the Royal
