for the stipulation gives the enemy nothing which he had not before; the neutrality of a captive may be always secured by his imprisonment or death. He that is at the disposal of another may not promise to aid him in any injurious act, because no power can compel active obedience. He may engage to do nothing, but not to do ill.
There is reason to think that Cowley promised little. It does not appear that his compliance gained him confidence enough to be trusted without security, for the bond of his bail was never cancelled; nor that it made him think himself secure, for at that dissolution of government which followed the death of Oliver he returned into France, where he resumed his former station, and staid till the Restoration.
