Claiborne made no overt legal attempts to re-assert control over Kent Island during the commission's rule of Maryland, although a treaty concluded during that time with the Susquehannocks claimed that Claiborne owned both Kent and Palmer Islands. Claiborne's legal designs on Maryland were once again defeated when Oliver Cromwell returned Calvert to power in 1653, after the Rump Parliament ended. In 1654, Governor Stone of Maryland tried to reclaim authority for the proprietor and declared that Claiborne's property and his life could be taken at the Governor's pleasure. Stone's declaration was ignored and Claiborne and Bennett again overthrew him, creating a new assembly in which Catholics were not allowed to serve. Calvert, now angry at Stone for what he perceived as weakness, demanded that Stone do something, and in 1655 Stone reclaimed control in St. Mary's and led a group of soldiers to Providence (modern Annapolis). Stone was captured and his force defeated by local Puritan settlers, who took control of the colony. Given the new situation, Claiborne and Bennett went to England in hopes of convincing Cromwell to change his mind but, to their dismay, no decision was made and, lacking royal authority, the Puritans gave power over to a new governor appointed by Calvert. Going behind Claiborne's back, Bennett and another commissioner reached an agreement with Calvert that virtually guaranteed his continued control over Maryland through the remainder of the Protectorate.
