At the point this study ends, the islands were about to be engulfed by events driven in large part by the crisis of the British monarchy during the 1640s. In 1642 internal dissention in Jersey saw a petition presented to the House of Lords against Sir Philip de Carteret. He claimed to be adopting a bipartisan approach, but on his return to the island, in the face of a possible French threat, he declared for the Crown; he and his supporters were soon confined to their garrisons in Mont Orgueil and Elizabeth Castle, before the island was recaptured by the royalists under George Carteret in November 1643, soon after Sir Philip's death. Similarly in Guernsey, the party loyal to the Crown was besieged, in Castle Cornet under Sir Peter Osborne, although in this case their opponents continued to hold the island through the succeeding years, dominated by Pierre de Beauvoir, Pierre Carey and James de Havilland. In 1641 Samuel de la Place and Jean de la Marche went to England, becoming part of the Westminster assembly of divines in 1642, and promoting the adoption of Presbyterianism. This activity sums up the situation of the islands: with their own distinctive social, religious and political dynamic, closely related to the fate of their neighbours in Normandy and Brittany, and yet intrinsically part of the processes which affected the other dominions of their sovereign lord.
