In 1657, he visited England, and in his absence, he appointed Dr. Luke Barber Sr. (c. 1615–1668) to administer the government. Barber had been the household physician of Oliver Cromwell, the Lord Protector. Fendall returned February 26, 1658, and brought back an agreement from Cecil Calvert, 2nd Baron Baltimore (1605–1675). This agreement stated that the government was definitely restored to the proprietor, Governor Fendall, as well as a new commission curtailing his power as governor, with Philip Calvert (1626–1682), a younger brother of Cecil, as advisor. As a result of reading the Articles of Agreement from Lord Baltimore on March 23, Capt. William Fuller and the other commissioners formally surrendered the Provisional Government to Josias Fendall.
