During the short interval that elapsed between the death of Cromwell in September 1658 and the return of Charles II. in May 1660, the Tower contained many important prisoners. Among them were Lady Mary Howard, the daughter of the Earl of Berkshire, and another lady, a Mrs Sumner, both of whom appear to have been mixed up in Mordaunt’s conspiracy against Cromwell, as well as a Mr Ernestus Byron and a Mr Harlow for the same cause. Other Royalists then in the fortress were Lord Falkland, Lord Delaware, the Earl of Chesterfield, Lords Falconbridge, Bellasis, Charles Howard, and Castleton, who had all taken part in a Royalist rising in Cheshire under the leadership of Sir George Booth. None of these, however, suffered more than a short imprisonment. While the faction of the Parliament was making a desperate stand against the military party in the government of the country, an attempt was made by the former to seize the Tower. “The Lieutenant, Colonel Fitz, had consented that Colonel Okey, with 300 men, should be dispersed in the vicinity prepared for the enterprise, promising that on a certain day he would cause the gates to be opened at an early hour for the passage of the Colonel’s carriage, at which time Colonel Okey with his men, embracing the opportunity, might seize the guards and make themselves masters of the place. This plot, however, was discovered, and on the night before its intended execution Colonel Desborough being despatched from the Army, with a body of horse, changed the guards, seized the Lieutenant, and placed a fresh garrison in the Tower under the command of Colonel Miller” (Ludlow’s “Memoirs”). Shortly after this episode, and during a disturbance amongst the soldiers there, Lenthal, the Speaker of the House of Commons, proceeded to the Tower, and removing the Lieutenant, who had been appointed by the Committee of Safety, conferred the government of the fortress upon Sir Anthony Ashley Cooper. But when General Monk declared for the King, that officer seized the fortress in the name of his royal master, released many of the prisoners, and placed in it a garrison commanded by Major Nicholson. It was now the turn of the Royalists, and in the month of March 1660, Sir Arthur Hazelrigge and Colonel John Lambert were placed in the Tower because they had opposed Monk’s design for the restoration of the King, an event which showed the other members of the Committee in which direction the wind was blowing, and they made an attempt to secure the Tower by victualling the fortress, with the intention of standing a siege if it were necessary. Ludlow proposed that a force of two thousand men should join Colonel Morley’s regiment in the Tower, that the building itself should be stored with provisions for six months, and that two thousand sailors should also be placed within its walls as an additional security for its defence. This scheme, however, came to nothing.
